The San Francisco Bay area is known for high STD rates, but there’s a big difference between San Francisco itself and the surrounding cities. In 2015, there were 1,115 people living with HIV or AIDS in Solano County, with a prevalence rate of 307 per 100K people, under California’s rate of 376 and a small fraction of San Francisco’s HIV prevalence rate.
But health officials are more worried about bacterial STD rates, which are going up sharply. In 2017, 2,618 people in Solano County were diagnosed with chlamydia, at a rate of 598.7 per 100K people, which is actually higher than California’s rate of 552.2. The gonorrhea and syphilis rates were 181.8 and 10.3. The group with the highest STD rates is 20–24-year-olds.
Health officials stress that sexually active people must use protection every time and get tested often.
You can be tested for STIs at Solano County Family Health Services on Courage Dr. Planned Parenthood is located on Travis Blvd. They test for STIs and treat all except HIV, and the fee is on a sliding scale. There are even more options the closer you get to San Francisco, and you will probably be able to find free STD testing there.
