STD stats & rates
How reported STI rates in San Mateo County, the county that includes Millbrae, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~22% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#26 of 58 California counties for chlamydia, a higher rate than 55% of the state
| Infection | San Mateo County | California | United States |
|---|---|---|---|
| Chlamydia | 360.4 2,618 cases ▼ 27% | 491.1 | 492.2 |
| Gonorrhea | 125.3 910 cases ▼ 34% | 190.2 | 179.5 |
| Syphilis (P&S) | 9.2 67 cases ▼ 44% | 16.3 | 15.8 |
| Syphilis (early) | 11.6 84 cases ▼ 39% | 19.1 | 16 |

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.
Between 2020 and 2023 in San Mateo County, chlamydia has risen from 263.1 to 360.4 per 100,000 (37%), gonorrhea has risen from 108.3 to 125.3 per 100,000 (16%), and P&S syphilis has fallen from 12.3 to 9.2 per 100,000 (25%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in San Mateo County.
Local HIV snapshot
San Mateo County HIV care continuum (2023)
San Mateo County recorded 12.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among San Mateo County residents living with HIV, 75.4% are in care · 55.4% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
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 Mateo County tests for syphilis.

Data & references
Local context
El Camino Real runs straight through Millbrae, and the clinics listed on this page sit close enough that most residents are looking at a short drive rather than a cross-county trip, which matters when a Tuesday afternoon is already accounted for three times over. That schedule pressure is real here: with nearly two-thirds of working-age residents in the labor force and unemployment low, most households are running on a tight clock, not a loose one. What shapes daily life further is that Millbrae leans heavily toward ownership, with a solid majority holding mortgages on homes worth well into seven figures, yet the roughly one-in-three households who rent are managing some of the steepest monthly costs in the Bay Area.
When rent runs that high, out-of-pocket health expenses get weighed carefully, so the fee tiers and insurance options shown on the clinic cards on this page carry genuine weight for a portion of residents. The city's younger adults, people in their late teens and twenties who are statistically in the years when STI transmission peaks, live alongside a community that skews toward married couples and larger household sizes averaging more than three people.
Getting there
At 9.65/20 on the EPA walkability index, day-to-day errands in Millbrae generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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).
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
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.
