STD stats & rates
How reported STI rates in Marin County, the county that includes Lagunitas-Forest Knolls, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~14% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#38 of 58 California counties for chlamydia, a higher rate than 34% of the state
| Infection | Marin County | California | United States |

| Chlamydia | 294.4 749 cases ▼ 40% | 491.1 | 492.2 |
| Gonorrhea | 97.1 247 cases ▼ 49% | 190.2 | 179.5 |

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 Marin County, chlamydia has risen from 214.2 to 294.4 per 100,000 (37%), gonorrhea has risen from 50.7 to 97.1 per 100,000 (92%), and P&S syphilis has fallen from 6.9 to 5.1 per 100,000 (26%).

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 Marin County.
Local HIV snapshot
Marin County HIV care continuum (2023)
Marin County recorded 10.8 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Marin County residents living with HIV, 74.8% are in care · 71% 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 Marin County tests for syphilis.

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.
