STDs & HIV in San Francisco County: the local picture
Here's how reported STI rates in San Francisco County — the county that includes San Francisco — compare with California and U.S. averages, based on the most recent 2023 surveillance data.
An estimated ~30% of San Francisco County residents are aged 15–34 (ACS) — the age group with the highest reported chlamydia and gonorrhea rates nationally, which is why local screening access matters here.
Lower chlamydia rate than 2% of the state's 58 counties (ranked #2)

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread — a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.

Among San Francisco County residents living with HIV, 95.5% know their status · 80.8% are in care · 75.7% are virally suppressed.
Early, routine testing is what moves these numbers — it is the entry point to PrEP, treatment, and viral suppression.

Congenital syphilis — passed from parent to baby in pregnancy — is the fastest-rising STI in the country.
U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023.

These are the federal Medicare reference prices for processing each lab test. Public clinics and the
community health centers serving San Francisco often test free or on a sliding scale; private labs and at-home kits
bundle several tests into one fee. Use this as a per-test benchmark before you pay out of pocket, or see the full

Prevention & treatment
PrEP, prevention & online treatment
Testing is one step. For residents of San Francisco, telehealth covers the rest of the picture — HIV-prevention
medication (PrEP) and DoxyPEP to lower future risk, and discreet online treatment if a result comes back
positive. All prescribed by licensed U.S. clinicians.
Prevent (PrEP & DoxyPEP)
Daily or on-demand medication that prevents HIV — and DoxyPEP, which lowers the risk of syphilis, chlamydia and gonorrhea.

Privacy
Confidentiality & consent in California
The questions San Francisco residents ask most before testing, answered under California law — which sets confidentiality and consent the same way statewide. Prefer to keep your name off the record? See our guide to anonymous STD testing.
Can a minor consent?
In California, minors aged 12 and older can consent to confidential STI testing and treatment on their own — no parental permission is required.
Will it show on my insurance?
If you use health insurance, an Explanation of Benefits (EOB) may be mailed to the policyholder. Under HIPAA you can ask your insurer in writing to send communications confidentially. To keep a test fully private, choose a self-pay private lab, an at-home kit, or a public health clinic — none of these bill your insurance.
Anonymous & no-insurance options
Public health clinics and at-home kits let you test without involving insurance or your regular doctor. Many California health departments offer free or low-cost STI testing, and several sites provide anonymous HIV testing.
Can my partner be treated too?
Yes. California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication to pass to your partner — no separate exam or appointment needed for them.
