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 2011. This information is divided into trend tables (2000-2011) and
yearly tables (2000-2011) 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 (2000-2011), you may select tables for cases ranked by
county, rates, and data by age and gender. For trend tables (2000-2011), you may select tables
for selected STDs, trends by age and gender, and comparisons of 2006 through 2010
information with 2011.
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.
