Data and Statistics

The following tables and reports provide data on new diagnoses of HIV infection, persons living with diagnosed HIV infection and deaths among persons with an HIV infection. Diagnoses of HIV infection include persons with a diagnosis of HIV infection (not AIDS), a diagnosis of HIV infection and a later AIDS diagnosis, and concurrent diagnoses of HIV infection and AIDS. Persons living with diagnosed HIV infection represent all persons ever diagnosed and reported with an HIV infection who have not been reported as having died by December 31 of the reporting year. Deaths among persons with an HIV infection represent deaths attributed to any cause among persons reported with a diagnosis of HIV infection.

Guidance for Users of Ohio HIV/AIDS Surveillance Data

Explanation of Terms

Ohio’s HIV/AIDS surveillance data tables provide useful information on new diagnoses of HIV infection, persons living with an HIV infection, and deaths among person with an HIV infection reported to the ODH from physicians, hospitals, outpatient facilities and labs. A diagnosis of HIV infection refers to persons newly diagnosed and reported with an HIV infection in a particular year, regardless of the stage of disease at initial diagnosis. This includes persons newly diagnosed with HIV (not AIDS), persons previously diagnosed with HIV who are now newly diagnosed with AIDS, and persons concurrently diagnosed with HIV and AIDS at initial diagnosis. Persons living with diagnosed HIV infection represent all persons ever diagnosed and reported with an HIV infection since the beginning of the epidemic living in Ohio who have not been reported as having died. Deaths among persons with an HIV infection represent deaths attributed to any cause among persons reported with a diagnosis of HIV infection.

Reporting Delays/Lags

A key consideration for the analysis of HIV/AIDS surveillance data requires the factoring in of reporting delays. A reporting delay – the time between diagnosis of HIV and/or AIDS and report of the case to the public health authority – can differ among exposure, geographic, racial/ethnic, age, sex and vital status categories. In some instances, reporting delays for mode of exposure (i.e., risk factor) can be several years, even with active follow-up to obtain this key information.

All population-based disease surveillance systems experience reporting lags and incomplete reporting. The reporting lags for Ohio’s HIV/AIDS surveillance data range from 6-18 months. This is an acceptable range and is recognized as meeting the CDC national quality standards for HIV/AIDS reporting. This allows states time to collect more complete and accurate information so that the data can be used to accurately identify trends in HIV transmission and populations at risk.

Representativeness and Limitations of Data

HIV infection surveillance data represents confidential reports of HIV infection and AIDS diagnoses, though not all persons with an HIV infection. The distinction here is that HIV diagnosis data represent the earliest date of diagnosis reported to the ODH HIV/AIDS Surveillance Program. The earliest date reported may not be the earliest date an individual became aware of their HIV infection. Individuals may have previously tested anonymously or were diagnosed out-of-state prior to being confidentially tested and reported to Ohio. HIV infection surveillance data may underestimate the level of recently infected persons because some infected persons do not know they are infected as they have not sought testing or have sought testing but did not respond to learn their test results. Reporting of behavioral risk information may not be complete as some persons diagnosed with an HIV infection may be reluctant to disclose their sexual and drug use history.

Due to the long and variable period from initial HIV infection to the development of AIDS; trends in AIDS surveillance do not represent recent HIV infections. Asymptomatic HIV-infected persons are not represented by AIDS case data. In addition, incomplete HIV or CD4+ t-cell testing may interfere with the representativeness of reporting. Widespread use of HAART complicates the interpretation of AIDS case surveillance data and estimation of the HIV/AIDS epidemic in an area. Newly reported AIDS cases may reflect treatment failures or the failure of the health care system to halt progression of HIV infection to AIDS. AIDS cases represent late-stage HIV infection.

Ohio Data

Detailed tables are presented for the most current year available, with data presented by selected characteristics and transmission categories for Ohio. A summary report includes a trend graph to visually display history of HIV and AIDS in Ohio since the beginning of the epidemic. The annual report provides descriptive summary reports analyzing HIV/AIDS surveillance data including new diagnoses of HIV infection, persons living with diagnosed HIV infection, and deaths among persons with an HIV infection presented by sex, age, race/ethnicity, transmission and exposure categories and geographic area in Ohio. A Power Point presentation describing the epidemiology and scope of HIV infection in Ohio is also included. Additionally, a HIV Continuum of Care report provides information regarding linkage to care and other continuum of care measures for persons diagnosed with HIV in Ohio.

Age Group
Census data for Race/Ethnicity groups for certain age groups (<13 and 13-14 years) are no longer available. Age groups in the reports will include 0-9 and 10-14 years. Trend data has been updated to reflect this change.

AIDS Diagnoses
Previously, diagnoses of AIDS included only persons diagnosed with AIDS while living in Ohio who had also initially been diagnosed with HIV infection while living in Ohio. This methodology has been changed to include persons diagnosed with AIDS while living in Ohio, regardless of where they were living at time of initial diagnosis of HIV infection. Trend data has been updated to reflect this change.

Persons Living With Diagnosed HIV Infection
In a continued effort to ensure accuracy of data, some historical records have been reconciled with other states, resulting in a decrease in prevalence numbers in some geographical areas, when it is determined the person is living outside of Ohio. Trend data has been updated to reflect this change.

Regional Data

Data Tables and Care Continuum Reports are presented for the HIV Prevention Planning Regions.

County Data

Data Tables are presented for Ohio counties with the greatest HIV disease. The HIV surveillance data included in the Ohio county reports is based upon cases of HIV infection diagnosed and reported to the Ohio Department of Health. The HIV surveillance data included in each Ohio county report may differ.

  • Reports are included for both new reported diagnoses of HIV infection and persons living with diagnosed HIV infection for Ohio counties with a population of greater than 200,000 and at least 5 new reported diagnoses. Data suppression rules are applied for case counts <5 where the relevant substrata category has fewer than 100 persons. Zeros are displayed.

  • Reports are included for persons living with diagnosed HIV infection for Ohio counties that do not meet the minimum population and number of new reported diagnoses described above that have at least 100 reported persons living with diagnosed HIV infection. Data suppression rules are applied for case counts <5 where the relevant substrata category has fewer than 100 persons. Zeros are displayed.

  • For counties not meeting either criteria described above, total case counts are included in the Ohio tables.

Age Group
Census data for Race/Ethnicity groups for certain age groups (<13 and 13-14 years) are no longer available. Age groups in the reports will include 0-9 and 10-14 years. Trend data has been updated to reflect this change.

Special Population Highlights

Brief written overviews of HIV/AIDS surveillance data with graphics, tables and narrative focusing on different at-risk populations to highlight disparities in HIV diagnoses in Ohio.

End the HIV Epidemic

The Ohio Department of Health (ODH) will use funds awarded from the Centers for Disease Control and Prevention (CDC) to strategically partner with local public health departments, community service agencies, and HIV healthcare providers in the three Ohio counties identified by CDC – Cuyahoga, Franklin and Hamilton – to plan and implement localized activities to support an End the HIV Epidemic (EtHE) Plan. The goal of the EtHE plan is to reduce new HIV infections by 90% by 2030 by implementing strategies related to the four pillars of the EtHE initiative: Diagnose, Treat, Prevent, and Respond.

The ODH HIV Surveillance Program led the development of Epidemiologic Profiles for these counties by convening a workgroup of internal and external stakeholders. These Epidemiologic Profiles will serve as a key focal point to guide state and local HIV planning, implementation, and evaluation of the EtHE Plan. Epidemiologic Profiles will increase understanding of data among local prevention and care planning bodies and community partners, and guide local planning activities in the three counties.

Epidemiologic Profile

The comprehensive epidemiologic profile is produced quinquennially (every five years) and provides detailed information on the current status of the HIV/AIDS epidemic in Ohio. It serves as a valuable resource for state and local HIV Prevention and Ryan White HIV Care Services programs for planning and evaluation. This report describes the general population of Ohio, persons with HIV infection in Ohio, persons at risk for HIV infection in Ohio and service utilization patterns among HIV-infected persons in Ohio. The profile includes extensive analysis and discussion of HIV/AIDS-related data from numerous data sources including general socio-demographic characteristics of Ohio's general population.

Special Analysis

Special analyses include reports of HIV/AIDS surveillance data and other data sources focusing on different at-risk populations in Ohio.
