INTRODUCTION This report provides a summary of HIV/AIDS cases reported in Orange County through December 31, 2010. It is our hope that in providing accurate and timely information, we can assist in reducing the spread and impact of HIV throughout Orange County. This report supplements the information given through the annual HIV/AIDS Fact Sheet, data requests, website reports and presentations, and oral presentations at public meetings. HIV/AIDS Surveillance Program Orange County s HIV/AIDS surveillance is conducted through active surveillance to identify and collect information on cases of HIV and AIDS diagnosed at hospitals, clinics, private physician offices, laboratories, and community-based organizations (CBOs). Mandated reporters, including laboratories and health care providers, submit reports of HIV cases to the. HIV/AIDS Surveillance Communicable Disease Investigators (CDIs) then contact and visit sites to facilitate the completion of HIV/AIDS case reports. Case reports are entered into the County s HIV/AIDS registry. Until May 2009, the HIV/AIDS Surveillance and Monitoring Program of the Orange County Health Care Agency maintained the Centers for Disease Control and Prevention s (CDC) HIV/AIDS Reporting System (HARS) registry. The HARS registry included all reported cases of HIV and AIDS who were residents of Orange County at the time of diagnosis. In June 2009, the California Office of AIDS (OA) transitioned to the electronic HIV/AIDS Reporting System (ehars) and began maintaining data for the local health jurisdictions (LHJs). Because of this change, the Orange County HIV/AIDS Surveillance and Monitoring Program began relying on the HIV Case Registry (Registry), a local database containing information on individuals receiving care in Orange County, including those who reside outside of the county. However, all cases described in this report are only of those individuals who resided in Orange County at the time of their initial HIV or AIDS report. The Registry database is dynamic due to the nature of HIV disease reporting, and data extracted from the Registry is considered provisional. The database is updated as duplications are resolved and additional information is added. Therefore, a snapshot of the database is extracted at the end of each calendar year and is used to present data up until that point in time. The most current extraction will be the most up-to-date number for previous years; and therefore data reported each year will be different from that reported previously. The data in this report was extracted on December 31, 2010. This will be indicated with the note Data as of December 31, 2010. It is also important to note that while the Registry includes a comprehensive record of individuals who have been diagnosed and reported by name with HIV/AIDS, the Registry does not include individuals who have not been diagnosed with HIV and/or reported by name but are living with the disease. The Centers for Disease Control and Prevention (CDC) estimates that 21% of all individuals living with HIV/AIDS are undiagnosed and do not know their status. 1 Using the CDC recommended Estimated Back Calculation Methodology 2, as of December 31, 2010 there were an estimated 1,752 undiagnosed persons living with HIV/AIDS in Orange County who are not represented in this report. Update on Name-Based HIV Case Reporting Orange County AIDS case surveillance is a core public health activity that began in Orange County in 1981. Non-AIDS HIV case surveillance, which mandates laboratory reporting of confirmatory HIV tests, began in California in July 2002. Between July 2002 and April 16, 2006, 2,155 cases of HIV were reported in Orange County using a non-named, coded case reporting system. Based on recommendations by the CDC, in April 2006, California law was revised to require the reporting of HIV cases by name rather than by non-named code. 1 ML Campsmith, P Rhodes, HI Hall, and others. HIV Prevalence Estimates -- United States, 2006. Morbidity and Mortality Weekly Report. 57(39):1073-1076. October 3, 2008. 2 CDC s Estimated Back Calculation = 0.21/0.79 x 6,591 reported persons with HIV disease as of December 31, 2010. 1

As of December 31, 2010, a total of 3,099 named non-aids HIV cases have been reported; this includes 2,014 or 93.5% of Orange County cases initially reported by non-named code that have been converted to a named HIV/AIDS case. CDC considers an area s name-based reporting to be mature after four years of reporting to allow for stabilization of data collection and for adjustment of the data in order to monitor trends. 3 Therefore, Orange County considers its name-based HIV reporting system to be representative of reported cases in the county. HIV Disease In an effort to better track the progression of the HIV/AIDS epidemic and conform to new guidelines presented by the CDC, this report will focus on HIV disease. The term HIV disease is used to describe the entire HIV spectrum, from initial HIV infection to advanced HIV disease (also known as AIDS). An AIDS (Acquired Immune Deficiency Syndrome) diagnosis is given to an HIV-positive person who has a CD4 count of less than 200/mm 3 (or under 14%) or a history of an "AIDS-defining illness." The HIV disease data presented in this report combines all AIDS cases reported and all HIV cases reported by name since April 17, 2006. For comparison purposes and to more fully understand the HIV epidemic, Appendix I breaks down HIV disease by HIV (non- AIDS) and AIDS diagnoses, by year reported and diagnosed. 3 Centers for Disease Control and Prevention, Diagnoses of HIV infection and AIDS in the United States and Dependent Areas, 2008 2

EXECUTIVE SUMMARY Since reporting began (1981 for AIDS cases and 2006 for HIV cases), Orange County has reported 10,846 HIV Disease cases to the Centers for Disease Control and Prevention (CDC) as of December 31, 2010. Of these, 7,747 have been diagnosed with AIDS and 4,255 have died. Orange County cases represented 5% of California AIDS cases and 7% of California HIV cases. Orange County ranks fifth highest among California s 58 counties in number of AIDS cases reported and fourth highest in the number of HIV cases reported. Chapter 1: HIV Disease in Orange County Of the 10,846 HIV Disease cases reported by Orange County between 1981 and 2010, a total of 6,591 (60.8%) were living as of December 31, 2010. This translates to a rate of 207.1 persons living with HIV Disease (PLWHD) per 100,000 Orange County population. In 2010, there were 261 HIV Disease (185 HIV (non-aids) and 76 AIDS) cases 1 diagnosed in Orange County residents, for a rate of 8.2 cases per 100,000 Orange County population. This number is preliminary, as cases diagnosed in 2010 will continue to be reported in 2011 and beyond. By gender: o 5,742 PLWHD are male (87.1%), 815 female (12.4%), and 34 (0.5%) are transgender male to female. o Of cases diagnosed in 2010, 239 (91.6%) were male, 20 (7.7%) female, and fewer than five were transgender male to female. By race/ethnicity: o 3,302 PLWHD are White (50.1%), 2,630 are Hispanic (39.9%), 346 are Black (5.2%), and 280 (4.2%) are Asian/Pacific Islander (API). o In 2010, 125 (47.9%) of cases diagnosed were Hispanic, 94 (36.0%) were White, 29 (11.1%) were API, and 13 (5.0%) were Black. By age: o The majority of PLWHD is currently age 40 years and over (4,762 or 72.3%) and is overrepresented in comparison to Orange County s population (44.1%). Persons under the age of 20 years account for 43 (0.7%) of PLWHD, and persons age 20-39 years account for 1,786 (27.1%) of PLWHD. o Of cases diagnosed in 2010, 165 (63.2%) were age 20-39 years at diagnosis, 87 (33.3%) were age 40 years and over, and 9 (3.4%) were under age 20 years. By mode of transmission o The majority of PLWHD are men who have sex with men (MSM) (4,791 or 72.7%), followed by persons infected through heterosexual contact (669 or 10.2%), persons who injected drugs (IDU) (598 or 9.1%), and MSM/IDU (289 or 4.4%). o In 2010, 223 (85.4%) of cases diagnosed were MSM, followed by heterosexual contact (18 or 6.9%), and IDU and MSM/IDU equally (9 or 3.4% each). Progression to AIDS o 1,548 or 45.6% of persons diagnosed with AIDS after 1995 were concurrently diagnosed with HIV. o Persons with the highest percentage of concurrent diagnoses were: Males (1,357 or 45.9%) API (77 or 52.4%) MSM (1,090 or 46.0%) 1 By year of HIV diagnosis. There were an additional 47 AIDS cases diagnosed with AIDS during 2010 but with HIV prior to 2010. 3

o o 666 (19.6%) of persons diagnosed with AIDS after 1995 were diagnosed within one year of their HIV diagnosis. Persons with the highest percentage of transitioning to AIDS within one year of their HIV diagnosis were: Males (586 or 19.8%) API (35 or 23.8%) Persons infected through heterosexual contact (82 or 22.8%) HIV Disease Survival o 2,035 (81.7%) of persons diagnosed with AIDS between 1996 and 2005 were still alive within five years of their AIDS diagnosis. o Persons with the highest survival rates were: Females 264 (82.5%) Hispanics 929 (84.1%) Persons infected through heterosexual contact 238 (88.8%) HIV Disease Mortality o Deaths of persons diagnosed with HIV disease peaked in 1992 with 373 deaths, regardless of cause, occurring that year. o This coincides with the peak in deaths due to HIV/AIDS. In 1992 there were 301 HIV/AIDS deaths, for an age-adjusted death rate of 11.9 deaths per 100,000 Orange County population. Chapter 2: Geography of HIV Disease in Orange County The most populous cities in Orange County are Santa Ana and Anaheim, with over 300,000 residents. These cities both have the largest numbers (between 454 and 1,372) of PLWHD at time of diagnosis. By rate, Laguna Beach is the city most heavily impacted by HIV Disease in Orange County. There are 453 PLWHD in Laguna Beach, which translates to 18 PLWHD for every 1,000 residents. In comparison, there are four PLWHD for every 1,000 persons in Santa Ana and three per 1,000 in Anaheim. In 2010, there are 23.7 new diagnoses for every 100,000 persons living in Laguna Beach, followed by 18.7 per 100,000 in Santa Ana and 12.2 per 100,000 in Anaheim. By gender: o 445 (98.2%) of PLWHD in Laguna Beach are male. o 760 (83.6%) of PLWHD in Anaheim are male. o 1,135 (82.7%) of PLWHD in Santa Ana are male. By race/ethnicity: o 398 (87.9%) of PLWHD in Laguna Beach are White, 36 (7.9%) Hispanic, 11 (2.4%) Black, and 6 (1.3%) API. o 928 (67.6%) of PLWHD in Santa Ana are Hispanic, 324 (23.6%) are White, 78 (5.7%) Black, and 36 (2.6%) API. o 513 (56.4%) of PLWHD in Anaheim are Hispanic, 298 (32.8%) are White, 52 (5.7%) Black, and 40 (4.4%) API. By age: o 238 (52.5%) of PLWHD in Laguna Beach are age 50 years and over; 214 (47.2%) ages 20-49 years. o 652 (71.7%) of PLWHD in Anaheim are ages 20-49 years, 248 (27.3%) age 50 years and over, and 9 (1.0%) under age 20. o 936 (68.2%) of PLWHD in Santa Ana are ages 20-49, 427 (31.1%) are age 50 years and over, and 9 (0.7%) under age 20. 4

By mode of transmission o 412 (90.9%) of PLWHD in Laguna Beach were infected through MSM, 22 (4.9%) MSM/IDU, and 8 (1.8%) IDU or were infected through heterosexual contact. o 866 (63.1%) of PLWHD in Santa Ana were infected through MSM, 207 (15.1%) IDU, 171 (12.5%) were infected through heterosexual contact, and 70 (5.1%) MSM/IDU. o 627 (69.0%) of PLWHD in Anaheim were infected through MSM, 117 (12.9%) were infected through heterosexual contact, 91 (10.0%) IDU, and 34 (3.7%) MSM/IDU. Chapter 3: Pediatric HIV Disease in Orange County Between 1991 and 1995, there were 17 pediatric HIV Disease cases diagnosed in Orange County, the peak five-year time period since the first pediatric case was diagnosed in 1984. This number had decreased to five by 2006-2010. Overall, 60 pediatric cases have been diagnosed. As of December 31, 2010, 42 of the 60 children diagnosed before the age of 13 were living (70.0%) By gender: o Females account for 23 (54.8%) of PLWHD who were diagnosed as a child; males 19 (45.2%). By race/ethnicity: o 24 (57.1%) of pediatric PLWHD are Hispanic, 9 (21.4%) are White, 6 (14.3%) are Black, and less than five persons are API. By age: o 12 (28.6%) of persons diagnosed as a child are currently still under the age of 13. 17 (40.5%) are currently age 13-19 years, and 13 (30.9%) are age 20 years and over. By mode of transmission o 39 (92.9%) of perinatal PLWHD were infected perinatally. Chapter 4: HIV Counseling and Testing The Orange County Health Care Agency provides support for HIV counseling and testing services in Orange County through the provision of HIV rapid test kits funded by the California Department of Public Health, Office of AIDS. Counseling and Testing (C&T) sites receiving kits include: 17 th Street Testing and Treatment, AIDS Services Foundation (ASF), the Health Care Agency Risk Reduction, Education, and Community Health (REACH) Program, and The Center Orange County. In 2010, 9,003 persons were tested at Orange County Counseling and Testing sites. Of these, 88 (1.0%) tested positive for HIV. By gender: o 80 (1.2%) of males tested positive, while only 6 (0.3%) of females tested positive. By race/ethnicity: o 51 (1.2%) of Hispanics, 23 (0.8%) of Whites, and 8 (0.8%) of APIs tested positive. There were fewer than five positive tests among Blacks. By age: o 38 persons age 20-29 years and 23 persons age 30-39 years had positivity rates of 1.0%, while persons age 40-49 years had a positivity rate of 1.2% (17 positive tests). 5

By mode of transmission: o 68 (2.7%) of persons who indicated that they were MSMs tested positive, while only 8 (0.2%) of persons with heterosexual contact tested positive. By substance use in the past two years: o 30 (1.9%) of persons who reported the use of alcohol, 9 (1.8%) of persons who used marijuana, 15 (1.3%) of persons who used amphetamines, and 5 (1.1%) of persons who used cocaine tested positive. Chapter 5: Ryan White Act and Orange County The Ryan White Act was first authorized in 1990 and is the largest piece of federal legislation that offers funding for the care and treatment of PLWHD who have no other source for care. Three main goals of the Ryan White Act are: o To lessen the burden of treatment and care in areas most affected by HIV. o To foster a coordinated approach to core treatment and support of HIV services. o To build a community-based, strategic response to HIV from local organizations and advocates, as well as local public entities. There are three Eligible Metropolitan Areas (EMAs) and six Transitional Grant Areas (TGAs) in California. o An EMA is an area that has reported at least 2,000 AIDS cases in the most recent five years and has a population of at least 50,000 persons. o A TGA is an area that has 1,000 to 1,999 new AIDS cases in the most recent five years and has a population of at least 50,000 persons. Orange County is a TGA. Los Angeles, San Francisco, and San Diego (EMAs) have 40,669, 17,325, and 11,636 PLWHD, respectively. Orange County ranks third among the TGAs, with 6,591 PLWHD. Other TGAs include: o Inland Empire (8,399 PLWHD) o Oakland (7,105 PLWHD) o Sacramento (3,397 PLWHD) o Santa Clara (3,068 PLWHD) o Santa Rosa (1,252 PLWHD) 6

CHAPTER 1: HIV DISEASE IN ORANGE COUNTY Overall HIV Disease Case Reporting: Since reporting began (1981 for AIDS cases and 2006 for HIV cases), Orange County has reported 10,846 HIV disease cases to the Centers for Disease Control and Prevention (CDC) as of December 31, 2010. Of these, 7,747 have been diagnosed with AIDS and 4,255 have died. The overall case rate of HIV disease in Orange County is 8.2 per 100,000 residents. Orange County cases represented 5% of California AIDS cases and 7% of California HIV cases. Orange County ranks fifth highest among California s 58 counties in number of AIDS cases reported and fourth highest in the number of HIV cases reported. Summary of HIV and AIDS Prevalence and Incidence: The following section provides an overview of: HIV Incidence: Individuals with a current diagnosis of HIV (non-aids) who resided in Orange County at time of diagnosis. This does not include persons now diagnosed with AIDS. AIDS Incidence: Individuals with a current diagnosis of AIDS and resided in Orange County at time of diagnosis. Figure 1.1 (below) shows the number of PLWHD as of December 31 of each year between 2001 and 2010. As of December 31, 2010, there were an estimated 6,591 persons living with HIV disease (PLWHD) in the county. Of these: 3,716 were diagnosed with AIDS 2,875 were diagnosed with HIV (non-aids) 4,228 4,497 4,757 5,038 5,294 5,539 5,843 6,119 6,365 6,591 1:1

The term HIV disease is used to describe the entire HIV spectrum, from initial HIV infection to advanced HIV disease (also known as AIDS). Acquired immune deficiency syndrome (AIDS) first became reportable in 1981; an AIDS diagnosis is given to an HIVpositive person who has a CD4 count of less than 200/mm 3 (or under 14%) or a history of an "AIDS-defining illness." HIV infection, by name, without an AIDS diagnosis, first became reportable in California in 2006. The HIV disease data presented in this report combines all AIDS cases reported and all HIV cases reported by name since April 17, 2006. Figure 1.3 (next page) shows the number of HIV disease cases diagnosed by the earliest reported HIV diagnosis year 1 and the number of persons living with HIV disease (PLWHD) each year. 2 Table 1.1 at the end of this chapter corresponds to Figure 1.3 shown below. As shown: Trends in Incidence: The number of new cases peaked in the late 1980s and are currently approximately 325 to 375 cases each year. With 261 new cases diagnosed in 2010, the incidence rate of HIV disease in 2010 was 8.2 per 100,000 population. However, as 2010 diagnosed cases are considered provisional due to normal reporting delays, throughout this document, incidence for the past two years (2009-2010) are used when looking at disease trends in Orange County. Trends in Prevalence: The number of PLWHD has increased by about four to five percent each year. In 1995, highly active antiretroviral therapy (HAART) was introduced. Since then, the number of PLWHD increased 115% from 3,060 persons to 6,591, while the number of new cases decreased by about 33%. 1 HIV disease cases by year are by the year of their HIV diagnosis, regardless of what year their AIDS diagnosis was for cases diagnosed with AIDS. 2 The earliest diagnosis year shown is typically the year the person was diagnosed with HIV; in cases where the HIV date is missing or the HIV test was performed sometime after the AIDS diagnosis, the year of AIDS diagnosis is shown. 1:2

HIV Disease by Gender Persons diagnosed with HIV disease may self-report their gender in four different categories: (1) male; (2) female; (3) transgender male to female; or (4) transgender female to male. Due to the small number of transgender PLWHD, unless indicated, 3 transgender HIV disease cases are not included in the male or female category of figures in this section. Tables 1.2a-1.4 at the end of this chapter correspond to figures in this section. P revalence by Gender: Of the 6,591 PLWHD diagnosed in Orange County as of December 31, 2010, 5,742 male, 815 female, and 34 were transgender male to female. Figure 1.4 (right) shows the number of PLWHD as of December 31, 2010 compared to Orange County s 2010 population by gender. There were 5,742 male PLWHD and 815 female PLWHD. As shown: Males accounted for 87.1% of PLWHD compared to 49.6% of the population. Females are under-represented with 12.4% of PLWHD and 50.4% of the population. Transgender male to female 4 information is available for PLWHD. However, Orange County population for transgender persons is not available. Percent 100% 80% 60% 40% 20% Figure 1.4.

White males have the next highest rate at 430.4 per 100,000. Hispanic females have the second highest rate amongst females at 65.7 per 100,000. APIs have lowest rate among males and females. Figure 1.6 (right) shows the number of PLWHD cases per 100,000 Orange County residents by gender and current age. As shown: Among males and females, the highest rate of HIV disease is among persons age 40-49 years for both genders.

Mode of Transmission among Males: The vast majority (83.0%) of males living with HIV disease reported being exposed through men who have sex with men (MSM), followed by injection drug use (IDU), men who have sex with men who use injection drugs (MSM/IDU), and heterosexual contact. Mode of Transmission among Females: The majority (68.3%) of females living with HIV disease reported being exposed through heterosexual contact, followed by IDU (23.2%). Females were also more likely to be reported as having been exposed through other or unknown means, which includes blood transfusions.

HIV Disease Surveillance Statistics, 2010 Incidence by Gender: Figure 1.8 (below) displays the rate of HIV disease cases per 100,000 population by gender diagnosed each year between 1984 (the first year a female was diagnosed) and 2010. As shown, case rates of HIV disease among males have been much higher than among females. The highest rate of HIV disease diagnosis occurred in 1988 for both males (59.7 per 100,000) and females (5.7 per 100,000) and have since declined. In 2010, there were 239 new cases of HIV disease diagnosed among males and 20 new cases among females. Rate per 100,000 population 70 60 50 40 30 20 10 Figure 1.8.

Rates for 2010 are provisional due to reporting delays. Transgender cases are excluded from Figure 1.8 because they have fewer than five cases diagnosed in any given year. Mortality by Gender: Figure 1.9 (below) shows the death rate (due to any cause) per 100,000 population by gender per year in persons reported with HIV disease between 1987 (the first year with a female death) and 2010. Table 1.4 at the end of this chapter shows the number of deaths in each year for each gender. Since the beginning of the epidemic in 1980, 3,914 males and 338 females diagnosed with HIV disease have died. Death Rates among Males: The highest death rate among males was in 1992, with 28.0 deaths per 100,000 males in Orange County. Since the introduction of Highly Active Antiretroviral Therapy (HAART) in 1995, the death rate of PLWHD has decreased significantly.

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency HIV Disease by Race/Ethnicity: This section describes trends in HIV disease by race/ethnicity. HIV reporting complies with guidelines provided by the Federal Office of Management and Budget. 7 Persons diagnosed with HIV or AIDS are asked to report their race and ethnicity. To determine ethnicity, persons are asked whether they identify as Hispanic. Individuals are then asked to choose one or more of the following race categories: (1) American Indian or Alaskan Native (AI/AN); (2) Asian; (3) Black or African-American; (4) Native Hawaiian or Other Pacific Islander (NHOPI); and (5) White. For the purposes of this report, persons who indicate that they are Hispanic are shown as Hispanic regardless of race chosen. The remaining racial categories capture the race of persons who indicate that they are not Hispanic. Individuals who are Black or African-American are referred to as Black throughout this report. Due to the small numbers of NHOPIs, this category has been combined with Asians and both groups are included in the Asian/Pacific Islander (API) category. Due to their small numbers, individuals identifying as AI/AN are included in the Other/Unknown category along with non-hispanic individuals who identified with more than one racial category. Tables 1.2a, 1.2b, 1.5, 1.6, and 1.7 at the end of this chapter correspond to Figures 1.10 to 1.14 in this section. Prevalence by Race/Ethnicity: Of the 6,591 PLWHD in the county as of December 31, 2010, 3,302 were White, 346 were Black, 2,630 were Hispanic, and 280 were API. The remaining 33 were either American Indian/Alaskan Native (AIAN), more than one race, or were of unknown race. Figure 1.10 (below) compares PLWHD by race/ethnicity to the 2010 Orange County population. As shown: Whites are over-represented with 50.1% PLWHD versus comprising 44.0% of the population. Blacks are over-represented with 5.2% PLWHD versus comprising 1.4% of the population. Hispanics are over-represented with 39.9%, PLWHD versus comprising 35.9% of the population. APIs are under-represented at 4.2% PLWHD as compared to their representation in the population (16.4%). 100% 80% Figure 1.10.

As shown: Blacks in all age groups have the highest rate of PLWHD. Hispanics have the second highest rate per 100,000 population in all age groups of PLWHD. Whites, Hispanics, and APIs have higher rates of PLWHD in the age groups 30-39 years, 40-49 years, and 50-59 years than persons of all ages.

Figure 1.12 (next page) shows the distribution of PLWHD by mode of transmission 8 among each race/ethnicity. Mode of Transmission among Whites: A large majority (77.4%) of Whites reported being exposed through MSM followed by IDU, heterosexual contact, and MSM/IDU. Mode of Transmission among Blacks: Black PLWHD are the only racial/ethnic group that did not have a single exposure category reported as the major mode of transmission. Almost half (45.7%) of Black PLWHD reported being exposed through MSM. Compared to other groups, a larger proportion of Black PLWHD reported heterosexual contact (24.6%) and IDU (19.7%) as their mode of transmission. Mode of Transmission among Hispanics: 69.1% of Hispanic PLWHD reported being exposed through MSM, followed by heterosexual contact (13.3%), IDU (9.6%), and MSM/IDU (3.1%). Mode of Transmission among APIs: A large majority (71.7%) of API PLWHD reported being exposed through MSM, followed by heterosexual contact (13.1%). Compared to other racial/ethnic groups, a large proportion (8.4%) of API reported other/unknown as their mode of transmission. 8 See the HIV disease by Mode of Transmission section on page 1:12 for description of mode of transmission reporting. 1:7

Figure 1.13 (next page) shows the number of newly diagnosed HIV disease cases per 100,000 Orange County population by race/ethnicity and year of diagnosis. Due to the low number of cases diagnosed in most race/ethnicities between 1980 and 1984, this figure begins in 1985. Case rates peaked in 1988 for Whites, 1989 for Hispanics, and 1991 for Blacks, and have since continued to decline. In 2010, Blacks had the highest case rate (29.0), followed by Hispanics (10.8), Whites (6.6), and APIs (5.5). Since the beginning of the epidemic in Orange County, Blacks have been the most highly impacted by HIV disease with case rates ranging from 76.5 per 100,000 in 1991 to 24.1 per 100,000 in 2006. 9 In 1992, Hispanics became the racial/ethnic group with the second highest case rate and have remained so since. Prior to 1992, Whites had the second highest HIV disease case rates in the county. Case rates among APIs have been the lowest among all racial/ethnic groups and have remained relatively constant since the beginning of the epidemic. 9 Due to the small number of Black cases diagnosed each year, case rates in this community can appear to shift significantly from year to year. 1:8

Since the beginning of the epidemic, 3,029 Whites, 209 Blacks, 930 Hispanics, and 72 API diagnosed with HIV disease have died. Table 1.7 at the end of this chapter shows the number of deaths in each year for each race/ethnicity. Death rates among all racial/ethnic groups shown have declined since their peak in the early 1990s. Black PLWHD have consistently had the highest death rates among all race/ethnicities in Orange County. 8 Prior to 1995, Whites had the second highest death among all race/ethnicities. Since 1996 death rates among White and Hispanics began to look increasingly similar. The number of API deaths is not displayed due to the low number of deaths (fewer than five) in most years.

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency HIV Disease by Age: This section describes trends in HIV disease by age groups. When describing individuals currently living with HIV disease (prevalence), the current age of the individual is used. When describing trends in the number of new cases (incidence), the age of diagnosis is used. Age groups for which there are fewer than five cases in each subgroup are not shown. Tables 1.2a, 1.2b, 1.8, 1.9, and 1.10 at the end of this chapter correspond to Figures 1.15 to 1.18 in this section. See Chapter 3 for a more detailed description of pediatric HIV/AIDS (HIV disease among children under age 13 at time of diagnosis) in Orange County. Prevalence by Current Age: Of the 6,591 PLWHD in the county as of December 31, 2010, 12 were under 12 years of age, 31 were between ages 13-19, 500 were between ages 20-29, 1,286 were between ages 20-29, 2,464 were between ages 40-49, 1,688 were between ages 50-59, and 610 were age 60 or over. Figure 1.15 (below) compares the current age of PLWHD to the 2010 Orange County population. As shown, the vast majority (82.5%) of PLWHD are between the ages of 30 and 59 compared to Orange County s population (42.2%). 100% 80% Figure 1.15.

See Figure 1.11 on page 1:6 to see the rate per 100,000 of PLWHD by race/ethnicity and current age. Figure 1.16 (next page) shows the distribution of PLWHD by mode of transmission 10 for five different age groups (by current age). Those currently under the age of 13 are discussed in Chapter 3. Mode of Transmission among 13-19 year-olds: 41.9% of persons currently age 13-19 have MSM as a mode of transmission, while 54.8% have a pediatric mode of transmission. Mode of Transmission among 20-29 year-olds: The vast majority (78.5%) of 20-29 year-old PLWHD reported being exposed through MSM, followed by heterosexual contact (8.8%). This is the age group with the highest proportion of PLWHD who reported exposure through MSM and the lowest proportion of PLWHD who reported being exposed through IDU. Mode of Transmission among 30-39 year-olds: The majority (72.0%) of PLWHD ages 30-39 reported being exposed through MSM, followed by heterosexual contact (13.3%). This age group had the largest percentage of individuals who reported heterosexual contact as a mode of transmission and the lowest percentage who reported other/unknown as a mode of transmission. 10 See the HIV disease by Mode of Transmission section on page 1:12 for description of mode of transmission reporting. 1:10

HIV Disease Surveillance Statistics, 2010 Mode of Transmission among 40-49 year-olds: For persons currently ages of 40-49, 72.6% reported being exposed through MSM, followed by heterosexual contact (10.3%), and IDU (9.1%). Mode of Transmission among 50-59 year-olds: Though the largest proportion of 50-59 year-old PLWHD reported being exposed through MSM, this was the smallest percentage of all age groups to report MSM as a mode of transmission. This age group also had the highest proportion who reported IDU as a mode of transmission (14.5%) compared to all other age groups. Mode of Transmission among Individuals Over 60 Years: For PLWHD currently ages 60 or older, 74.4% reported being exposed through MSM, followed by heterosexual contact (10.7%), and IDU (6.6%).

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency Incidence by Age at Diagnosis: Of the 590 new cases of HIV disease diagnosed in 2009-2010, 194 were between ages 20-29, 157 were between ages 30-39, 142 were between ages 40-49, and 79 were age 50 or over at time of diagnosis. Figure 1.17 (below) shows the rate per 100,000 population by age at diagnosis of cases diagnosed each year within each age group. In general, case rates have declined since their peak in 1988 for all age groups. Until 2006, persons aged 30-39 consistently had the highest case rates. Until 1998, persons aged 40-49 had the second highest case rates. Persons 50 years or older have consistently had the lowest case rates among age groups shown.

Mortality by Age at Diagnosis: Figure 1.18 (below) shows the death rate (due to any cause) per 100,000 population by age groups (by age at diagnosis) per year in persons reported with HIV disease. Since the beginning of the epidemic, 784 of those diagnosed between the ages of 20-29, 1,799 of those diagnosed between the ages of 30-39, 1,013 of those diagnosed between the ages of 40-49, and 630 of those diagnosed between at age 50 or over have died. Table 1.10 at the end of this chapter shows the number of deaths in each year for each age group. Death rates among all age groups were highest in the early 1990s and have since continued to decline. In general, death rates have been highest among 30-39 year-olds, followed by 40-49 year-olds, 20-29 yearolds, and lowest among those over 50 years of age. Around 1998, death rates among all age groups have become increasingly similar. Rate per 100,000 population 40 30 20 10 Figure 1.18.

HIV Disease Surveillance Statistics, 2010 HIV Disease by Mode of Transmission: This section describes trends in HIV disease by mode of transmission. The term mode of transmission is used to summarize a person s possible HIV risk factors. Individuals diagnosed with HIV or AIDS are asked to report potential modes of transmission. The Orange County HIV/AIDS reporting system uses a hierarchy established by the Centers for Disease Control and Prevention (CDC), in determining the primary mode of transmission for each HIV disease case. Persons with more than one reported risk factor for HIV infection are classified in the transmission category listed first in the hierarchy. The following are modes of transmission listed in hierarchical order for adults: (1) men who have sex with men (MSM); (2) injection drug use (IDU); (3) men who have sex with men who use injection drugs (MSM/IDU) (4) treatment for hemophilia (5) heterosexual contact (with person known to have or at high-risk for HIV); (6) received transfusion of blood or blood components/transplant; (8) adult, confirmed other risk; (9) cannot be classified in above categories. Modes of transmission for pediatric cases (children under age 13 at time of diagnosis), listed in hierarchical order, include: (1) treatment for hemophilia; (2) mother has HIV/AIDS or has had sex with someone with or at-risk for HIV; (3) received transfusion of blood or blood components/transplant; (4) pediatric other risk; (5) pediatric, confirmed other risk; and (6) cannot be classified in above categories. For the purposes of this report, persons whose mode of transmission could not be classified in any of the transmission categories will be shown as Unknown. Due to their small numbers (fewer than five cases), many of the mode of transmission categories are not shown in this report or are shown as Other. See Chapter 3 for more detailed description of pediatric HIV/AIDS in Orange County. Tables 1.2a, 1.2b, 1.11, and 1.12 at the end of this chapter correspond to Figures 1.19 to 1.21 in this section. Prevalence by Mode of Transmission: Of the 6,591 PLWHD in the county as of December 31, 2010, 4,791 were MSM, 669 were reported to be infected through heterosexual contact, 598 were IDU, 289 were MSM/IDU, and 244 were infected through other or unknown means. Figure 1.19 (below) displays the proportion of PLWHD by reported mode of transmission. As shown, MSM accounted for the largest proportion of prevalent cases (72.7%), followed by persons infected through heterosexual contact (10.1%) and IDU (9.1%). MSM/IDU accounted for 4.4% of prevalent cases, and the remaining 0.8% of cases were attributed to transfusion or hemophiliac (T/H), unknown adult risk category, and pediatric cases. Figure 1.19. PLWHD by Reported Mode of Transmission, Orange County T/H, 0.8% Heterosexual, 10.2% Unknown, 2.2% Pediatric, 0.7% MSM/IDU, 4.4% IDU, 9.1% MSM, 72.7% See Figure 1.7 on page 1:4 to see PLWHD by gender and mode of transmission. See Figure 1.12 on page 1:7 to see PLWHD by race/ethnicity and mode of transmission. See Figure 1.16 on page 1:10 to see PLWHD by current age and mode of transmission. 1:13

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency Incidence by Mode of Transmission: Figure 1.20 (below) presents cases diagnosed by mode of transmission by year of diagnosis. 11 Exposure through MSM has consistently been reported as the highest mode of transmission. Since 1996, the second highest reported mode of transmission has been heterosexual contact; prior to that, IDU was the second highest mode of transmission in Orange County. Cases reported as acquired through a transfusion, transplant, or by a hemophiliac have declined since the beginning of the epidemic, as have cases in pediatric cases (persons infected under the age of 13). 600 500 Figure 1.20.

Mortality by Mode of Transmission: Figure 1.21 (below) shows the number of deaths per year in persons reported with HIV disease between 1987 and 2010 by age at diagnosis. 10 Those reported as exposed through MSM have consistently had the highest number of deaths among individuals diagnosed with HIV disease; the number of deaths peaked in 1992 for this group. IDU has generally been the exposure group with the second highest number of deaths. Deaths among those exposed through MSM/IDU had been the mode of transmission group with the third highest number of deaths until 1997 when the number of deaths became increasingly similar to those found among those reported to be exposed through heterosexual contact. 300 Figure 1.21.

HIV Disease Surveillance Statistics, 2010 Progression from HIV to AIDS The introduction of HAART in 1996 has substantially prolonged the interval between the diagnosis of HIV infection and the development of AIDS. 12 Since 1996, Orange County has reported 3,405 AIDS cases. HIV infection, by name, without an AIDS diagnosis, first became reportable in California in 2006. Due to the relative newness of HIV (non-aids) reporting compared to AIDS reporting, the dates of HIV (non-aids) diagnosis are sometimes unknown or incomplete, especially for individuals diagnosed well before 2006. There are 10 individuals diagnosed with AIDS after 1995 for which an HIV diagnosis date is unknown. This section describes the time between diagnosis of HIV infection and AIDS diagnosis for these 3,395 persons for which an HIV and AIDS diagnosis date is known. Transgender male to female are included in the female percentage in Figures 1.22 through 1.24 due to the small number of cases. Table 1.13a at the end of this chapter correspond to Figures 1.22 and 1.23 in this section. Figure 1.22 (below) shows the proportion of individuals who were diagnosed with HIV at the same time (concurrently) as AIDS for persons who received their diagnoses after 1995 (since the introduction of HAART). The proportion of all individuals who were concurrently diagnosed with HIV and AIDS 45.6%. The proportion of males, Hispanics, API, and those who reported transmission through heterosexual contact received concurrent HIV and AIDS diagnoses compared to the overall proportion. 100% Figure 1.22.

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency HIV Disease Survival The widespread use of HAART beginning in 1996 in the United States has resulted in a large reduction in mortality rates among HIV infected persons. HIV/AIDS is now conceptualized as a chronic illness, to be managed in similar ways to diseases like diabetes, where a major goal of therapy is to prevent later complications and ensure quality of life. This section describes the characteristics of the 2,492 individuals who were diagnosed with AIDS between 1996 and 2005. Table 1.13b at the end of this chapter correspond to Figure 1.24 in this section. Figure 1.24 (below) shows the proportion of individuals surviving five or more years after receiving an AIDS diagnosis for persons diagnosed with AIDS between 1996 (since the introduction of HAART) and 2005. The overall five-year survival after AIDS for persons diagnosed with AIDS between 1996 and 2005 is 81.7%. Differences in survival occurred across gender, race/ethnicity, and mode of transmission categories. By Gender: The proportion of males surviving five or more years after an AIDS diagnosis is almost the same as the overall proportion, while the proportion of females and transgender male to female with fiveyear survival exceeded the overall proportion. By Race/Ethnicity: The proportion of Whites, Blacks, and API who have survived five or more years since receiving their AIDS diagnosis is lower than the overall proportion. By Mode of Transmission: The proportion of IDU who have survived five or more years since receiving their AIDS diagnosis is lower than the overall proportion. Figure 1.24.

A date of death may be reported through the following sources: (1) a death notice from an Orange County HIV service provider; (2) a death certificate provided by County of Orange Vital Records; (3) an update from the State Office of AIDS; or (4) through matching living cases with the annual file of death certificates certified by Orange County Vital Records. Persons diagnosed with HIV disease may die of any cause, although the majority of deaths are due to HIV disease. When a death notification is received, the date of the person s death is added to the HIV Case Registry and their vital status is changed to deceased. Though these modes are meant to capture all instances in which a person may be deceased, there are instances when death notifications do not occur (e.g. if the person moves out of the country and no death records exist in the United States). Therefore, it is possible that some of the persons counted as living with HIV disease may actually be deceased. Table 1.4 at the end of this chapter corresponds to Figure 1.25 in this section. 1:16

HIV Disease Surveillance Statistics, 2010 Figure 1.25 (below) shows the number of deaths of persons reported with HIV disease as residents of Orange County between 1981 and 2010, regardless of cause of death. As shown, there was a dramatic decrease in deaths after the introduction of HAART in 1995. As of December 31, 2010, the cumulative number of deaths reported was 4,255, which represented 39% of the 10,846 cases reported with HIV disease during the same time period.

The 9 th Revision of this code (ICD-9) applied to deaths that occurred from 1979 until 1998; the 10 th Revision (ICD-10) applied to deaths since 1999. The figure includes deaths due to HIV disease in Orange County as indicated by the ICD-9 between 1987 (the first year HIV disease deaths were reported) and 1998 and deaths due to HIV disease as coded by the ICD-10 since 1999.The ICD-10 included 1.1 times as many deaths coded as due to HIV disease as ICD-9. 14 The age-adjusted death rate considers the number of deaths occurring in a specified age group divided by the midyear population of the age group. Age-adjusted death rates allow comparison of mortality risk among groups or over time within a particular age group. 1:17

HIV Disease Surveillance Statistics, 2010 HIV Disease Rates by City The overall HIV disease rate in Orange County in 2010 was 8.2 per 100,000. This rate is based on the number of new cases per 100,000 population. Because it considers the population of an area, disease rates may provide a better depiction of the impact of a disease on the population. Figure 2.4 (below) shows a map of the PLWHD per 100,000 population based on city of residence at time of diagnosis. Figure 2.5 (below) shows the 10 cities with the highest HIV Disease rate. As shown: Laguna Beach is the city most heavily impacted by HIV Disease in Orange County. There are 453 PLWHD in Laguna Beach (as shown in Figure 3), which translates to nearly 1,800 PLWHD for every 100,000 residents. Aliso Viejo, Anaheim, Costa Mesa, Dana Point, Laguna Niguel, Santa Ana, and Tustin are the next most heavily impacted areas with between 216.1 to 383.7 PLWHD per 100,000 residents. Figure 2.4.

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency HIV Disease in Select Cities: Anaheim, Laguna Beach, and Santa Ana This section provides the demographics of persons who live in the three cities in Orange County with the highest number of PLWHD at time of diagnosis: Anaheim, Laguna Beach, and Santa Ana. Anaheim The city of Anaheim is located in the northern region of Orange County. Home to 353,643 residents 6, Anaheim is the second most populous city in Orange County. Anaheim is also home to the second highest number of PLWHD at time of diagnosis (909 PLWHD) and has the fifth highest rate of PLWHD (257.0 per 100,000). Laguna Beach Laguna Beach is a coastal city located in the south west region of the county and is home to 25,354 residents 6. Since the beginning of the epidemic, Laguna Beach has been the city most heavily impacted by HIV Disease in the county when looking at the number of cases for the size of the population. Laguna Beach is home to the third highest largest number of PLWHD at time of diagnosis (453 PLWHD). Due to the small number of residents in Laguna Beach, the city has, by far, the highest rate of PLWHD per 100,000 (1,786.7 per 100,000 population). Santa Ana Located in central Orange County, Santa Ana is the most populous city in the county with 357,754 6 residents. Santa Ana is challenged by some of the highest hardship indicators in the county; almost one in five (19.8%) residents in the city live below 100% of the federal poverty level compared to almost one in 10 (9.9%) 7 in Orange County. Santa Ana is home to the largest numbers of PLWHD at time of diagnosis (1,373 PLWHD) and has the second highest rate of PLWHD (383.8 per 100,000 population). Incidence in Select Cities: Figure 2.6 (below) shows the number of newly diagnosed HIV Disease cases per 100,000 population in Anaheim, Laguna Beach, Santa Ana, and Orange County by year of diagnosis. Anaheim: HIV Disease case rates peaked in 1988 (38.5 cases per 100,000) and have since declined to an average of 15 cases per 100,000 for the past five years, which has been slightly higher than rates in the county. Laguna Beach: Since the beginning of the epidemic in Orange County, Laguna Beach has been the most most highly impacted city by HIV Disease with case rates over 350 per 100,000 population between 1987 and 1989, dropping to an average of 38 cases per 100,000 in the past five years. Santa Ana: Since 1987 HIV Disease case rates in Santa Ana have consistently been higher than the Orange County average. Rates peaked in 1988 and have since dropped to an average of 21 cases per 100,000 (five year average). Rate per 100,000 population 400 300 200 100 Figure 2.6.

HIV Disease Surveillance Statistics, 2010 Prevalence in Select Cities by Gender 8 : Figures 2.7.a-2.7.d (below) show the distribution of PLWHD by gender in Orange County (Figure 2.7.a), and the cities of Anaheim (Figure 2.7.b), Laguna Beach (Figure 2.7.c), and Santa Ana (Figure 2.7.d). As shown, Anaheim and Santa Ana have slightly higher proportions of female PLWHD compared to Orange County while Laguna Beach has a much higher proportion of male PLWHD. Anaheim (Figure 2.7.b): The majority (83.6%) of PLWHD diagnosed while residents of Anaheim are male. However, compared to Orange County, there is a slightly higher proportion of female PLWHD (15.6% in Anaheim vs. 12.4% in Orange County) and transgender male to female PLWHD (0.8% in Anaheim vs. 0.5% in Orange County) who were diagnosed while residents of Anaheim. Laguna Beach (Figure 2.7.c): The vast majority (98.2%) of PLWHD who were diagnosed while residents of Laguna Beach are male. This is much higher than the county-wide proportion of male PLWHD. Santa Ana (Figure 2.7.d): The majority (82.7%) of PLWHD diagnosed while residents of Santa Ana are male. However, compared to the county overall, there is a higher proportion of female PLWHD (16.3% in Santa Ana vs. 12.4% in Orange County) and transgender male to female PLWHD (0.9% in Santa Ana vs. 0.5% in Orange County) who were diagnosed while residents of Santa Ana.

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency Prevalence in Select Cities by Race/Ethnicity 9 : Figures 2.8.a-2.8.d (below) show the distribution of PLWHD by race/ethnicity in Orange County (Figure 2.8.a), and the cities of Anaheim (Figure 2.8.b), Laguna Beach (Figure 2.8.c), and Santa Ana (Figure 2.8.d). As shown, the racial/ethnic makeup of the epidemic varies greatly from city to city. Anaheim (Figure 2.8.b): The majority (56.4%) of PLWHD diagnosed while residents of Anaheim are Hispanic, while 32.8% are White. There is a greater proportion of Hispanic PLWHD and a smaller proportion of White PLWHD as compared to Orange County as a whole. The proportion of Black, API, and Other/Unknown PLWHD is also slightly higher than that in Orange County. Laguna Beach (Figure 2.8.c): The vast majority (87.9%) of PLWHD who were diagnosed while residents of Laguna Beach are White. This greatly contrasts with Orange County where only half of PLWHD are White. Santa Ana (Figure 2.8.d): A large majority (67.6%) of PLWHD diagnosed while residents of Santa Ana are Hispanic, while almost one in four (23.6%) are White. PLWHD diagnosed while residents of Santa Ana are much more likely to be Hispanic (67.6% compared to 39.9% of Orange County) and much less likely to be White (23.6% compared to 50.1%). PLWHD diagnosed while residents of Santa Ana are also slightly more likely to be Black (5.7% compared to 5.2% in the county). White 50.1% Figure 2.8.a.

HIV Disease Surveillance Statistics, 2010 Prevalence in Select Cities by Current Age 10 : Figures 2.9.a-2.9.d (below) show the distribution of PLWHD by current age in Orange County (Figure 2.9.a), and the cities of Anaheim (Figure 2.9.b), Laguna Beach (Figure 2.9.c), and Santa Ana (Figure 2.9.d). Anaheim (Figure 2.9.b): The largest percent of PLWHD diagnosed while residents of Anaheim are between the ages of 40 and 49. The proportion of PLWHD under age 39 diagnosed while residents of Anaheim is higher compared to Orange County as a whole, while the proportion who are age 50 years or over is lower. Laguna Beach (Figure 2.9.c): The two largest age groups of PLWHD diagnosed while residents of Laguna Beach are 40-49 year-olds (36.6%) and 50-59 year-olds (36.2%), while those age 60 years and over make up 16.3% of PLWHD. PLWHD diagnosed while residents of Laguna Beach are older compared to those in diagnosed in Orange County; over half (52.5%) of PLWHD diagnosed while residents of Laguna Beach are age 50 years or over, compared to just over one-third of Orange County PLWHD. Santa Ana (Figure 2.9.d): Those in the 40-49 age group make up the largest proportion (37.0%) of PLWHD diagnosed while residents of Santa Ana. PLWHD diagnosed while living in Santa Ana are much more likely to be in the 30-39 age group compared to PLWHD diagnosed in Orange County (23.7% compared to 19.5%) and less likely to be 50 years of age or older.

HIV Disease Surveillance Statistics, 2010, County of Orange, Health Care Agency Prevalence in Select Cities by Mode of Transmission 11 : Figures 2.10.a-2.10.d (below) show the distribution of PLWHD by mode of transmission in Orange County (Figure 2.10.a), and the cities of Anaheim (Figure 2.10.b), Laguna Beach (Figure 2.10.c), and Santa Ana (Figure 2.10.d). Anaheim (Figure 2.10.b): A large majority (69.0%) of PLWHD diagnosed while residents of Anaheim reported being exposed through men who have sex with men (MSM) followed by heterosexual contact, injection drug use (IDU), and MSM/IDU. These proportions generally reflect those of Orange County as a whole. Laguna Beach (Figure 2.10.c): The vast majority (90.9%) of PLWHD diagnosed while residents of Laguna Beach reported exposure through MSM. This is much higher than the proportion of PLWHD who reported exposure through MSM diagnosed in Orange County. Santa Ana (Figure 2.10.d): For PLWHD diagnosed while residents of Santa Ana, 63.1% reported being exposed through MSM, followed by IDU (15.1%), and heterosexual contact (12.5%). Compared to Orange County as a whole, PLWHD diagnosed in Santa Ana are less likely to report MSM as a mode of transmission and much more likely to report heterosexual contact and IDU as a mode of transmission.

CHAPTER 3: PEDIATRIC HIV DISEASE IN ORANGE COUNTY Overview of Pediatric HIV Reporting This section describes trends in HIV Disease for pediatric cases (children under the age of 13 at time of diagnosis). As of December 31, 2010, there have been a total of 60 pediatric cases (children under the age of 13) reported in Orange County. This represents less than 1% of total HIV Disease cases reported in the county. Most (82%) of these pediatric cases are attributed to perinatal transmission, or transmission from mother to child during pregnancy, labor, or delivery. Due to the small numbers of pediatric cases, reported each year 1 data is presented in five or ten year periods. In this report, when describing individuals currently living with HIV Disease (prevalence), the current age of the individual is shown. When describing trends in the number of new cases (incidence), the age of diagnosis is used. Age groups for which there are fewer than five cases in each subgroup will not be shown in this section. Incidence Figure 3.1 (below) displays the number of pediatric cases diagnosed (by age at diagnosis) since 1986 in fiveyear periods by the earliest date of diagnosis. As shown, between 1996-2000 and 2001-2005, there was a significant decrease in the number of pediatric cases. This is likely due to decreases that began in 1994 after research showed that zidovudine (ZDV) given to pregnant women infected with HIV and their newborns reduced the risk for this type of HIV transmission. Since then, the testing of pregnant women and treatment for those who are infected have resulted in a dramatic decline in the number of children perinatally infected with HIV nationally. Cases diagnosed in 1986-1990 were due to perinatal transmission, a child receiving treatment for hemophilia, and children who were infected due to a blood transfusion. By 1996 until 2010, all the pediatric cases diagnosed have been due to perinatal transmission. By 2006-2010, 40.0% of the cases were in children born in the United States and not those infected because they were born in an endemic country. Figure 3.1.

HIV Disease Surveillance Statistics, 2010 Prevalence This section provides information on the 42 children living with HIV Disease (PLWHD) who were under age 13 at time of diagnosis. Comparisons are made to All PLWHD or the 6,591 PLWHD as of December 31, 2010 regardless of age at diagnosis and Orange County s total 2010 population. Prevalence by Gender Figure 3.2 (below) shows the proportion of pediatric PLWHD compared to Orange County s 2010 population by gender. As shown, the distribution of pediatric PLWHD is generally reflective of Orange County s population and does not reflect the disproportionate impact among males seen in PLWHD overall. Figure 3.2.

CHAPTER 4: HIV COUNSELING AND TESTING Overall HIV Counseling and Testing: The Orange County Health Care Agency provides support for HIV counseling and testing services in Orange County through the provision of HIV rapid test kits funded by the HIV Prevention Services Branch of the California Department of Public Health, Office of AIDS. Counseling and Testing (C&T) sites receiving kits include: 17 th Street Testing and Treatment, AIDS Services Foundation (ASF), the Health Care Agency Risk Reduction, Education, and Community Health (REACH) Program, and The Center Orange County. Tests conducted at private provider offices and other sites not listed here are not included in this chapter. This chapter describes the trends and demographics of those who received tests and those who tested positive for HIV at C&T sites between 2006 and 2010. C&T sites provide counseling and testing services at no cost to individuals. An individual may take more than one test in a single year or over multiple years. Therefore, the numbers in this chapter should not be considered an unduplicated count of individuals. Though no one is refused testing at these sites, it is important to note that the C&T sites target outreach to high-risk populations such as men who have sex with men, substance users, and partners of infected individuals. Therefore, positivity rates shown here are likely higher than those expected in the general population. Figure 4.1 (below), displays the number of tests provided each year at all of the C&T sites between 2006 and 2010. As shown, during this time, a total of 43,357 tests were conducted, with an average of 8,671 tests conducted each year.

CHAPTER 5: RYAN WHITE ACT AND ORANGE COUNTY Overview of Ryan White Act First authorized in 1990, the Ryan White Act is the largest piece of federal legislation that offers funding for the care and treatment of persons living with HIV disease (PLWHD) who have no other source for care. Three main goals of the Ryan White Act are: To lessen the burden of treatment and care in areas most affected by HIV. To foster a coordinated approach to core treatment and support of HIV services. To build a community-based, strategic response to HIV by local organizations and advocates, as well as local public entities. The Ryan White Act is administered by the U.S. Department of Health and Human Services (HHS), Health Resources and Services Administration (HRSA), HIV/AIDS Bureau (HAB). Federal funds are awarded to agencies located around the country, which in turn deliver care to eligible individuals under funding categories called Parts, as outlined below. The Ryan White legislation created a number of programs, called Parts, to meet the needs for different communities and populations affected by HIV/AIDS. Each is described below. Orange County receives funding from Ryan White Parts A, B, and C, as well as MAI to provide primary medical care and support services to HIVpositive individuals. Part A provides emergency assistance to Eligible Metropolitan Areas (EMAs) and Transitional Grant Areas (TGAs) that are most severely affected by the HIV/AIDS epidemic. A map of the EMAs and TGAs in California is shown on the next page. Orange County receives Ryan White Part A funds directly through the federal government as a TGA. The Orange County Health Care Agency (HCA) HIV Planning and Coordination Unit acts as Orange County s grantee for these funds. The Orange County HIV Planning Council acts as the planning body for Ryan White Part A funding. Part B provides grants to all 50 States, the District of Columbia, Puerto Rico, Guam, the U.S. Virgin Islands, and 5 U.S. Pacific Territories or Associated Jurisdictions. Orange County receives Ryan White Part B funds through the California Office of AIDS. Part C provides comprehensive primary health care in an outpatient setting for people living with HIV disease. The HCA s HIV Ambulatory Care Clinic (known as 17 th Street Care) receives Part C funds directly from the federal government to provide outpatient ambulatory medical care. Part D provides family-centered care involving outpatient or ambulatory care for women, infants, children, and youth with HIV/AIDS. Part F provides funds for a variety of programs: The Special Projects of National Significance Program grants fund innovative models of care and supports the development of effective delivery systems for HIV care. The AIDS Education and Training Centers Program supports a network of 11 regional centers and several National centers that conduct targeted, multidisciplinary education and training programs for health care providers treating people living with HIV/AIDS. The Dental Programs provide additional funding for oral health care for people with HIV. The Minority AIDS Initiative (MAI) provides funding to evaluate and address the disproportionate impact of HIV/AIDS on African Americans and other minorities. Orange County receives MAI funds directly through the federal government. 5:1
