There were 0 new HIV diagnoses in Lincoln County in 2020. HIV is the one infection where how soon you test changes which test you need — an RNA test detects it far earlier than a standard antibody test.

Lincoln County reported 179 chlamydia cases in 2023, a rate of 276.7 per 100,000 residents. Most people who have chlamydia or gonorrhea have no symptoms at all, so waiting for something to feel wrong is not a strategy.

Prevention & treatment

PrEP, DoxyPEP & Online Treatment

A test result is the start, not the end. If you are negative and want to stay that way, PrEP and DoxyPEP cut the risk of a future infection. If you are positive, most STIs can be treated without setting foot in a clinic. Both are available to people in Troy by video visit, prescribed by clinicians licensed in Missouri.
