STD stats & rates
How reported STI rates in Tuolumne County, the county that includes Long Barn, compare with California and U.S. averages, based on the most recent 2023 surveillance data.
#51 of 58 California counties for chlamydia, a higher rate than 12% of the state
| Infection | Tuolumne County | California | United States |
|---|---|---|---|
| Chlamydia | 167.9 91 cases ▼ 66% | 491.1 | 492.2 |
| Gonorrhea | 42.4 23 cases ▼ 78% | 190.2 | 179.5 |
| Syphilis (P&S) | 9.2 5 cases ▼ 44% | 16.3 | 15.8 |
| Syphilis (early) | 7.4 4 cases ▼ 61% | 19.1 | 16 |

Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Tuolumne County, chlamydia has fallen from 214 to 167.9 per 100,000 (22%), gonorrhea has fallen from 113.3 to 42.4 per 100,000 (63%), and P&S syphilis has fallen from 12.6 to 9.2 per 100,000 (27%).

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 Tuolumne County.
Local HIV snapshot
Tuolumne County HIV care continuum (2020)
Tuolumne County recorded 0 new HIV diagnoses per 100,000 (2020), against 14.9 statewide and 13.7 nationally. Among Tuolumne County residents living with HIV, 63.6% are in care · 50% 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 Tuolumne 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.
