As a suburb of Seattle, Renton shares that city’s STD problems to some degree. In 2017, there were 6,798 people living with HIV or AIDS in King County, with a prevalence rate of 323.6 per 100K people. Along with exposure from sexual partners (use of protection has decreased), health officials in the county blame injection drug use, particularly heroin and meth, for the high rates.
Chlamydia is particularly prevalent among young women aged 15–24. In 2016, the chlamydia rate among this group only was 2,543.4 per 100K people in King County (among all groups together, the rate was 445).
Chlamydia is asymptomatic in the early stages, but it can lead to infertility if left undetected and untreated. It is imperative that every sexually active person be tested regularly, even if they are not experiencing symptoms. King County’s gonorrhea rate for 2016 was 162.8.
There are a few clinics in Renton, and more scattered across King County, including a women’s clinic that offers STD testing as part of their well woman exam. Some women may qualify for free STD testing there; they may need to bring proof of income to make sure.
King County Public Health has some STI clinics, including teen clinics, but not in Renton. The closest one to you is probably in Kent. The AFC Urgent Care in Kent also does STI testing.
