The Department of Health (DOH) collects information on sexually transmitted infections (STIs) in Washington State. This data comes from electronic laboratory and case reporting systems, as well as disease investigation services.
Why Is STI Data Important?
STIs affect the physical and mental health of people living with them. DOH saw over 40,000 cases of chlamydia, gonorrhea, and syphilis in 2022. STIs are curable and treatment options are available. STI data provide information that helps guide programs to reduce and treat infections. It can show which areas and populations are most affected, so they can be focused on.
What’s Here
The dashboards contain data on chlamydia, gonorrhea, and syphilis in Washinton for 2019-2022. This information can be filtered to show metrics based on race, sex, and year of diagnosis. The dashboards present rates and case counts at the Local Health Jurisdiction (LHJ) and regional levels.
Under DOH’s small numbers guidance, case counts less than 10 are suppressed, as well as rates associated with case counts less than 16. This protects Washington residents’ privacy by making sure they can’t be identified through the data we publish.

Get Tested
Anyone who is under the age of 25 and sexually active should get tested each year. Whatever age you are, if you think you may have been exposed to an STI, you and your sex partner(s) should visit a health clinic, hospital, or doctor for testing and treatment.
