  • HIV & STI Diagnosis Trend Reports

    STI Diagnosis Trends

    STI Diagnosis Trends, 2016-2025 (data as of July 2026)
    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.

    The overall trend in the P&S syphilis rate (per 100,000 population) within Michigan is rising.

    HIV Diagnosis Trends

    HIV Diagnosis Trends, 2016-2025 (data as of July 2026)
    This report includes 10-year trend analyses (negative binomial and Poisson) of people diagnosed with HIV in Michigan. Geographic and demographic breakdowns are analyzed. The slides highlight important information found in the tables. The tables include analyses of Michigan as a whole, the Detroit Eligible Metro Area (DEMA) and the Detroit Health Department (HD) jurisdiction.

    The rate of new HIV diagnoses significantly declined among residents of the Detroit Local Health Department (LHD) jurisdiction, the Detroit Metro Area (DMA), and the state of Michigan as a whole. There was no significant change in the Outstate region as a whole. New diagnoses decreased an average of 2.1% per year in the Detroit LHD and 1.9% per year in the DMA. The significant drop among Detroit City residents drove these declines, along with a significant decrease among Oakland County residents. Because the majority of persons diagnosed with HIV in Michigan reside in the DMA, the decrease at the state level is primarily due to the decrease in the DMA. However, outstate counties also contributed, with significant declines observed in Berrien and Ingham counties.

     

    HIV Diagnosis Trends - 2020 Special Report (data as of July 2021)
    This special report briefly explains why the sharp decline in new HIV diagnoses during 2020 was likely due to a lack of testing rather than a decrease in HIV transmission.

  • Medical Monitoring Project (MMP)

  • 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 Aphirm. 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 people with HIV 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 people receiving Ryan White and related services (not all people 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.
      • Aphirm 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 people 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 Aphirm 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.
