▶ Information about HIV and STIs: HIV & STIs 101
Annual STI Diagnoses & HIV Prevalence Report
This annual report provides the diagnoses during the most recent calendar year for reportable sexually transmitted infections (STIs), including chlamydia, syphilis, and gonorrhea. It includes geographic and demographic breakdowns and highlights disparities in case distribution. All data come from the Michigan Disease Surveillance System.
This report focuses on persons living with HIV December 31 of the given year. It includes geographic and demographic breakdowns, information regarding HIV Stage 3 (previously known as AIDS), HIV transmission rates, STI coinfections, and historic prevalence estimates. The slides highlight important information found in the tables. The tables include assessments of Michigan as a whole, as well as of the Detroit Metro Area (DMA) and the Detroit Local Health Department (LHD) jurisdiction.HIV & STI Diagnosis Trend Reports
This report includes 10-year trend analyses for Michigan residents diagnosed with an STI (syphilis, chlamydia, or gonorrhea). Trends are standardized for changing population, and diagnosis rate changes are evaluated for statistical significance using negative binomial regression. Breakdowns are geographic and demographic.
This report includes 10-year trend analyses (negative binomial and Poisson) of persons diagnosed with HIV in Michigan. Geographic, demographic, and linkage to care breakdowns are analyzed. It also includes minimal HIV testing information. The slides highlight important information found in the tables. The tables include analyses of Michigan as a whole, the Detroit Metro Area (DMA), and the Detroit Local Health Department (LHD) jurisdiction.HIV Care Reports
HIV Care Continuum Report, 2019 (data as of April 2020)
![A total of16,281 PLWH were diagnosed before Jan. 1, 2019 and still alive Dec. 31, 2019. 84% of those diagnosed PLWH were considered to be In Care during the year (defined as PLWH with at least one CD4, viral load, or genotype lab test during the year). 88% of the diagnosed PLWH in care (73% of diagnosed PLWH overall) were considered to be Virally Suppressed during the year (defined as PLWH with less than 200 copies of HIV virus per milliliter of blood [<200c/mL], according to their last viral load lab test during 2019). 58% of the diagnosed PLWH who were virally suppressed (43% of diagnosed PLWH overall) were considered to be Maintained Undetectable during the year (defined as PLWH who maintained viral load levels <200c/mL for at least 4-8 months).](/images/mdhhs/HIV_Continuum_of_Care_705267_7.png)
The Continuum of Care was developed by Centers for Disease Control and Prevention (CDC) to assess gaps in care. The report includes geographic and demographic breakdowns for persons living with HIV during the entire year (diagnosed before January 1 and still living with HIV December 31). The slides highlight important information found in the tables, which include assessments of Michigan as a whole, the Detroit Metro Area (DMA), and the Detroit Local Health Department (LHD) jurisdiction.Care Continuum and Housing, 2018 (created 2019)
This report compares care disparities among individuals with stable vs temporary or unstable housing. In all of Michigan's Public Health regions, persons with temporary of unstable housing experience poorer care outcomes.
Link-Up Michigan Outcome Report, 2019 (data as of July 2020)
This report contains information pertaining to the Link-up Michigan program for the city of Detroit and Michigan counties. The report details demographics for not in care residents, outcomes of Link-up investigations, care status for those who accepted care, Link-up investigation contact attempts, and barriers to receiving care. For more information regarding Link-up Michigan, please visit Link-Up MI.

Coinfections and Co-Diagnoses
This annual report looks at HIV prevalence among people diagnosed with new syphilis, gonorrhea, or chlamydia infections during 2019, as well as the rate of STI diagnoses among all people living with HIV in Michigan. The slides highlight the priority populations who are disproportionately affected by coinfection, while the tables show details by race and sex, age, transmission risk, and local health department. Data comes from the Michigan Disease Surveillance System (MDSS) and from the HIV/AIDS registry (eHARS).See Hepatitis B and C Annual Surveillance Report for data on people with hepatitis who are also living with HIV.

- HIV Mortality in Michigan, 2014
(data as of 2016)
The final 2020 NHAS Report will likely be delayed at least one year due to COVID-19. Most indicators are measured using HIV lab data. Due to the decrease of in-person medical appointments, a significant drop in HIV laboratory reports occurred during 2020. Therefore, new diagnoses and care rates observed during 2020 are low. Revisiting these indicators after 2021 will paint a more accurate picture of Michigan's progress toward the NHAS goals.

Interactive Vital Records Tables
This MDHHS Vital Records and Health Statistics Section website reports statistics for three types of sexually transmitted infections (STIs): chlamydia, gonorrhea, and syphilis. Syphilis is grouped by all syphilis, or as primary and secondary syphilis. Primary and secondary syphilis reports represent initial stages of syphilis, when transmission is most likely to occur. The website offers 20 years of information for each infection, with data divided into trend tables and yearly tables by gender, age, counties, and health districts.
National Data
Data Notes
- STI data comes from the Michigan Disease Surveillance System (MDSS). STI cases are dated using onset date, when available, then specimen collection date, if available, and then date referred to the MDSS if both other dates are missing. Cases included in reports are probable and confirmed based on CDC case definitions.
- HIV data comes from enhanced HIV/AIDS Reporting System (eHARS), CAREWare, and Evaluation Web. In Michigan, mandatory HIV lab reporting began in 2006. Therefore, diagnoses and care measures, in general, are based on laboratory reports.
- eHARS is a browser-based,Center for Disease Control and Prevention (CDC)-developed application that assists health departments with reporting, data management, analysis, and transfer of data to CDC. This system contains basic demographic information (age, race, gender, transmission risk, location) and HIV-related laboratory reports. Advantages: includes all PLWH who have resided in Michigan; entry/edit rights are restricted to a very small group of staff, ensuring clean and consistent data. Limitations: updates after diagnosis are limited to information included in laboratory reports. eHARS does not capture socio-economic information. Other notes: Prevalence is based on last known address. Major changes to last known address occurred in 2014 and 2020; therefore, reports published since 2020 may not be comparable to previous reports.
- CAREWare is a web-based, electronic health and social support services information system for the Health Resources and Services Administration’s (HRSA's) Ryan White HIV/AIDS Program recipients and providers. This system contains basic demographic information (date of birth, race, gender, transmission risk, location), socioeconomic factors (income, housing status, and health insurance provider), and Ryan White services received. Advantages: includes socioeconomic elements, and care service information not dependent on laboratory reports. Limitations: only includes persons receiving Ryan White and related services (not all persons living with HIV); the type of data entry/edits depends on the needs of the agency, which may result in more up-to-date, but less consistent, data, compared to eHARS. Other notes: CAREWare is used to produce federal reports, such as the Ryan White HIV/AIDS Program Services Report(RSR) and the AIDS Drug Assistance Program Data Report (ADR), and supplement eHARS-based reports, such as the Continuum of Care Report.
- Evaluation Web is a direct-entry database, developed by Luther Consulting, that contains 18-1802-funded HIV testing information and Partner Services data. This system contains demographic information, test results, risk information, and intervention referrals for persons tested for HIV in the State of Michigan. Advantages: includes positive and negative test results, and Partner Service networks not available in other systems. Limitations: restricted to PS18-1802-funded tests. Other notes: Much of the data collected in Eval Web is based on self-report.
- Population data comes from the U.S. Census Bureau and the National Center for Health Statistics. These data are used as the denominator in rate calculations so that HIV and STI outcomes can be compared across groups and geographies. Each year, the Census Bureau’s Population Estimates Program (PEP) uses current data on births, deaths and migration to calculate population change since the most recent decennial Census and produces a time series of estimates of population. The Census Bureau, however, does not release estimates by single-year of age at the county level due to concerns about the reliability of these estimates, so they are provided to us via the National Center for Health Statistics to meet programmatic needs (e.g., the creation of age groupings that differ from the standard groupings used by the Census Bureau). The Census Bureau’s American Community Survey (ACS) provides annual "5-year" estimates, which represent data collected over a period of time. Using the ACS 5-year estimates rather than the 1-year estimates for less populated areas and small population subgroups provides increased statistical reliability. Thus, these estimates are generally used for calculating rates for cities and race, sex, and age subgroups within cities.
