1 Licking County Health Department 212 INFECTIOUS DISEASE REPORT

2 Narrative The Licking County Health Department (LCHD) made several improvements in 212 related to surveillance, investigations, case reports, and evaluations of infectious diseases. The changes have allowed investigators to respond to infectious disease reports more efficiently and have made collaboration with partnering agencies much easier. Infectious Disease Manual: The LCHD Infectious Disease Manual was updated in 212. The following sections were revised or added to the document: Public Information and Press Release Laboratory Access After Action Reports and Evaluations Non compliance of Healthcare Provider for Communicable Disease Reporting and Template Foodborne Disease Outbreak Investigations Infectious Disease Evaluations: A new template was developed in 212 and is being used to assess the investigations of LCHD staff responding to infectious disease reports. Case Notes: Infectious disease investigators have developed a more descriptive and organized method to document case notes within the Ohio Disease Reporting System (ODRS). This approach provides more information than what is required in ODRS and allows other investigators to better comprehend each situation. Disease Thresholds: LCHD applied a new technique in 212 using historical data to set thresholds for diseases of questions and estimate if an outbreak was occurring to prompt an investigation. Epi Team: The LCHD Epi Team implemented a process to send alerts to members when a significant infectious disease event was occurring. This provided members with information on the status of each investigation. The LCHD Epi Team also added a representative from Licking Memorial Hospital to discuss emerging issues at each meeting. STD Task Force: LCHD formed a task force to address the rising rates of Chlamydia and Gonorrhea in the county. A partner notification project was developed to help treat both individuals and prevent reinfection.

9 STDs In 212, the rates for Chlamydia and Gonorrhea increased significantly compared to 211. Early projections estimated that Chlamydia was on the rise and as a result the Licking County Health Department decided to form an STD Task Force. The group addressed several issues and worked on a partner notification process to reduce rates. STD surveillance identified a large proportion of reinfections which prompted the targeting of partners for treatment. Figure 11: Chlamydia Figure 12: Gonorrhea In 212, the percentage of reinfection for Chlamydia was at 29.4% and 1.3% for Gonorrhea. This could imply that around 1 out of 3 people who have a positive test for Chlamydia will test positive again in Licking County. If an individual is diagnosed with an STD it s extremely important for the partner to be notified and tested. This needs to happen in order to prevent reinfection and lower STD rates in the county. The number of Gonorrhea cases for 212 was following a similar pattern to 211 until September when an increase was identified. Chlamydia was the primary focus of the STD Task Force but due to the late increase in Gonorrhea, both STDs will be addressed by the group. Syphilis information was made available in the Ohio Disease Reporting System in early 212 and will be tracked with the rest of the STDs. HIV/AIDS information is maintained by the Ohio Department of Health and the most current stats published were from 211.

A couple of unofficial reports of HFM were suspected in the county but could not be confirmed. H3N2v: Four confirmed cases of H3N2v were detected in Licking County. The Licking County Health Department prepared and collaborated with local partners to limit the spread of H3N2v which affected areas across the state. Norovirus: A total of five Norovirus outbreaks were identified throughout Licking County in 212. The virus caused illness in all ages and in different settings. The positive lab specimens from each outbreak contained the strain Norovirus GII.4_New Orleans. Pertussis: Several cases of Pertussis were reported in a timeframe which exceeded the health departments threshold and indicated the possibility of an outbreak. During the investigation, a number of cases were epidemiologically linked to one another which confirmed the existence of an outbreak. Salmonellosis: The laboratory results on a Licking County Salmonella case matched a multistate outbreak being tracked by the CDC. The strain responsible for the outbreak has been linked to hedgehogs. Unknown: There were two outbreaks where the causative agent could not be identified because lab specimens were unable to be collected. Notes:

Varicella Licking Rate Table 21: Top 5 Reportable Disease Ranking Change Comparison ( ) Reportable Disease Licking Rate Rate Change Pertussis % Meningitis aseptic/viral % Varicella % Mycobacterial disease % Three of the top 5 reportable diseases in Licking County from 211 were again in the same positions for 212. Hepatitis C chronic was the leading infectious disease reported in the county and in Ohio for 212 (not including STDs). Campylobacteriosis was again the second leading reportable infectious disease in Licking County and in 212 the rate decreased by 22.4%. An important consideration for Campylobacteriosis would be the status of the case classification and the type of test used to detect the bacteria. 75% of the cases reported in Licking County for 212 were classified as suspected due to the use of an antigen test. Studies have been conducted to evaluate the effectiveness of antigen tests to truly detect Campylobacter and the results have shown a high number of false positives. If Licking County just used the number of confirmed Campylobacter cases for 212 then the county rate would be at 7.8 and in the middle tier for the region. Discussion will take place to see if the antigen test can be used as a screening tool followed up by a culture to confirm the presence of Campylobacter in Licking County. A Pertussis outbreak contributed to an increased rate in 212 and placed third on the list for the leading reportable diseases in the county. Salmonellosis ranked fourth on the list with a 12.6% increase from 211. Varicella replaced Mycobacterial disease from 211 for the fifth place spot.

21 Conclusion Due to the increased rates of Chlamydia and Gonorrhea, STD Task Force members are working on new ideas to help educate and treat the people of Licking County. The group is still focusing on partner notification and treatment to bring rates down in 213. Influenza is no longer a reportable disease but LCHD staff are committed to tracking the number of cases in the county to provide information to the public. The Influenza Reporting Improvement System (IRIS) and participation by area providers makes this all possible. A weekly influenza report is published on LCHD s website which started in late 212. The IRIS report contains all of the data collected for the week and compares it to past years. Several outbreaks were reported in 212 and LCHD staff were able to respond to these events to limit their spread. Education was also provided to staff members where these outbreaks took place to assist with early detection and control measures for the future. Norovirus was an issue for the entire state in 212 and Licking County had 5 confirmed outbreaks. All of these outbreaks were controlled once the reporting location notified LCHD and provided recommendations. The Licking County Health Department will continue to conduct disease surveillance to help protect the people of Licking County.
