3 This report presents an analysis of HIV and AIDS surveillance data as of the end of 2004 within the Cook County Department of Public Health (CCDPH) jurisdiction. This region includes all of suburban Cook County, excluding the municipalities of Evanston, Oak Park, and Skokie, which have their own state-certified local health departments. By December , a cumulative total of 2,813 reported cases of AIDS and 1,040 cases of HIV were received by CCDPH. Based on these figures, the total number of persons living with AIDS at the end of 2004 was 1,341, and the total number of persons living with HIV was 1,018. Figure 1 presents the number of new cases of HIV and AIDS since Figure 2 presents the number of people living with HIV and AIDS for the same period. Because of a lag in reporting time, all cases diagnosed in 2003 and 2004 may not have been reported by the end of 2004, and therefore caution should be used when interpreting these data.

The proportion of female cases of AIDS has increased. For females accounted for 22% of reported cases or 1 in 5 cases. For , females represented 26% of newly reported AIDS cases or 1 in every 4 cases. Racial and ethnic disparities continue to be seen in AIDS incidence rates. The rate of AIDS in Blacks for (22.8 per 100,000) was 9.5 times higher than the rate in Whites (2.4 per 100,000). The rate in Hispanics (6.0 per 100,000) was 2.5 times the rate in Whites. The lower average incidence rate for (5.7 per 100,000) compared to (7.2 per 100,000) most likely reflects both a lag in reporting and improvements in treatment that slow progression from HIV to AIDS. AIDS-related mortality remains low, with an average rate of 2.3 deaths per 100,000 population for Since 1997, the mortality rate has remained fairly stable. 4

Since 1999, the annual number of reported HIV cases has averaged 133. There was a slight increase (5.6%) in the average annual number of male HIV cases cases for compared to 90 cases for By race/ethnicity, only Black HIV cases increased from an annual average of 47 for to an average of 52 for HIV cases that have MSM as their primary risk factor comprised the largest proportion of cases, averaging 37% of new cases in and 40% of cases in The average number of cases in the year old age group rose slightly for (34 cases) over the previous three-year period (28 cases). The largest numbers of cases for both periods were in the year age group. Due to the manner in which HIV is reported in Illinois -- by code number, a substantial proportion of cases lack risk behavior information and therefore, remain under investigation. For , these cases accounted for an average of 19% of reports; for , these cases averaged 27% of reports received annually. 6

For , the mean number of new AIDS cases reported was 127 cases per year. This compares to an average of 161 cases per year for As previously noted, this is most likely due in part to a lag in reporting. It may also reflect a true decrease in AIDS incidence due to improved HIV treatment. The proportion of female AIDS cases increased slightly to more than one-quarter of all cases for ; at the same time, the proportion of cases with heterosexual exposure rose above 25%. In 2004, more than half of all reported AIDS cases in CCDPH jurisdiction were Black (55%), continuing a trend seen since the year The distribution of AIDS cases by age remained essentially unchanged. 7

For , HIV cases in Blacks annually averaged 1.5 times the number of cases in Whites (68.8 vs. 46.6). During 2004, there were 34 Black male HIV cases reported, which was more than twice the number of White male cases (15). Black MSM cases (16) exceeded White MSM cases (10). This varies from the , where the average number of White MSM cases at 25.4 per year was greater than that for Black MSM cases at 19.8 per year. The number of IDU cases was highest among Black males with 7 cases in 2004; this is comparable to the annual number reported during The number of HIV cases among Black females (n=19) was nearly four times that of White cases (n=5). For , Black female cases have averaged 23.6 cases per year compared to only 9.4 cases per year for White females. 8

In 2004, the number of Black AIDS cases (47) was over twice the number of White cases (20), yielding a Black:White case ratio of 2.4:1. This represents a larger disparity than the Black:White case ratio for , which was 1.6:1. The number of Black male AIDS cases (35) for 2004 was slightly more than double the number of White male cases (17). Similarly, there were 19 MSM cases among Blacks, compared to 11 MSM cases among Whites. This varies from , where the average number of White MSM cases at 27.2 per year was similar to the average number of Black cases at 27.8 per year. Among females, there were 12 cases in Blacks compared to only 3 in Whites. In comparison, for the Black to White ratio of average annual female cases was 2.7 :1. Hispanic AIDS case data were lower than that for Whites. Data for 2004 were also lower than averages. 9

The average number of persons living with HIV more than doubled since the year 2000, from 492 to 1017 persons. The mean proportion of males and females living with HIV remained stable from The proportion of Hispanics living with HIV remained the same (13%) from The proportion of Blacks living with HIV continued to increase slowly from 42% of cases in 1999 to 47% of cases in Changes in transmission risk group data are difficult to assess due to the high proportion of cases still under investigation -- without a known risk behavior. Among cases with known risk behaviors, the proportion of cases with IDU as their primary risk has decreased from 17% of cases in 1999 to 13% of cases in This decrease may reflect a decrease in incidence or possibly a disparity in progression to AIDS for this particular sub-population. All age groups had relatively similar mean proportions of people living with HIV, with the highest proportion in the year age group. 10

The mean proportion of male and female persons living with AIDS (PLWA) remained stable from 1999 to By race ethnicity, very little change was seen in the distribution of persons living with AIDS. While apparent increases in Black PLWA and concurrent decreases in the White PLWA, none of these changes were statistically significant. Among transmission groups, the proportion of PLWA with Injection Drug Use (IDU) declined significantly from 23% in 1999 to 18% in This decline may reflect a reduction in the number of new cases with IDU. It may also represent a decrease in survival of PLWA in this risk behavior group. No significant change in the distribution of cases by age group was seen between 1999 and
