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 Diego County residents living with HIV, 84.6% know their status · 72% are in care · 60.9% are virally suppressed.

Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
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. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for San Diego County tests for syphilis.

National City Boulevard cuts straight through the heart of this city, and a clinic visit from the stretch near Kimball Park rarely means more than a few minutes on the road. That proximity matters most for the younger adults who make up a substantial slice of National City's population, people in their late teens and twenties navigating early relationships, often on tight schedules. With nearly two-thirds of residents renting and a typical monthly rent around $1,163, discretionary spending gets parsed carefully.
A testing visit that costs real money or burns a weekday afternoon off work creates a real obstacle, especially for the roughly one in fifteen residents who are currently out of work and balancing job searches alongside everything else. It can happen between errands, close to home, on a week when nothing else goes as planned.

Confidentiality & consent in CaliforniaMinor consent and partner treatment (EPT) under state law, plus how to test privately
Two things that actually depend on California law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
Can a minor consent on their own?
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
