Data for three types of sexually transmitted diseases (STDs), divided into four groups, are shown at this website: chlamydia, gonorrhea, primary and secondary syphilis (P&S syphilis) and all syphilis. Information for these diseases is presently available for the years 1996 through 2012. This information is divided into trend tables (2000-2012) and yearly tables (2000-2012) by gender, age, counties and health districts.

To view detailed information for your community, you may select from a variety of available tables. For yearly tables (2000-2012), you may select tables for cases ranked by county, rates, and data by age and gender. For trend tables (2000-2012), you may select tables for selected STDs, trends by age and gender, and comparisons of 2007 through 2011 information with 2012.

Please note that the information is obtained from health care facilities providing testing to individuals with sexually transmitted diseases. Therefore, it is complete only in so far as individuals have sought testing and records of such testing have been reported to the Michigan Department of Community Health. It is likely that the number of cases reported under represents the incidence of sexually transmitted diseases in the population. For chlamydia and gonorrhea, this under representation may be substantial.

It is important to note that there is no state requirement that individuals requesting services at family planning, WIC, MIC and other state sponsored outpatient clinics be tested for chlamydia. Although the state does provide testing support in some clinics, testing for chlamydia may be an additional expense for many service providers. Therefore some clinics in many counties may not routinely test clients for chlamydia. In addition, local municipalities may apply funds for such testing at their own discretion. This may lead to increased numbers of chlamydia cases being reported as greater funds are released for testing. Counties and local health departments where greater funds are made available for testing may show greater rates of chlamydia cases simply because they have been able to test more individuals.
