Mendocino Community Health Clinic in Ukiah tests for HIV, syphilis, chlamydia, gonorrhea, herpes, hepatitis C, and TB on a sliding scale with donations accepted; appointments are required, bacterial infections are treated same visit, and care is delivered in Spanish.
Clinical care at Mendocino Community Health Clinic is conducted in Spanish, which means conversations about treatment plans, medication adherence, and follow-up happen without a relay. The provider and patient are working from exactly the same information at every step.
Testing-only HIV programs leave ongoing medical management to chance and patchwork resources. Mendocino Community Health Clinic's Ryan White funding changes that, HIV care here runs from initial testing through sustained medical treatment, with medication adherence counseling built into the continuum.
Many STI clinics handle testing without touching HIV prevention prescriptions. At Mendocino Community Health Clinic, both PrEP and PEP are prescribed directly, and PrEP is available for uninsured patients, so prevention doesn't stall waiting on an outside provider.

STD stats & rates
How reported STI rates in Mendocino County, the county that includes Boonville, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~16% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#35 of 58 California counties for chlamydia, a higher rate than 40% of the state
| Infection | Mendocino County | California | United States |
|---|---|---|---|
| Chlamydia | 306.4 273 cases ▼ 38% | 491.1 | 492.2 |
| Gonorrhea | 67.3 60 cases ▼ 65% | 190.2 | 179.5 |
| Syphilis (P&S) | 30.3 27 cases ▲ 86% | 16.3 | 15.8 |
| Syphilis (early) | 13.5 12 cases ▼ 29% | 19.1 | 16 |
| Syphilis (late/unknown) | 19.1 17 cases ▼ 59% | 46.7 | 29.5 |

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 Mendocino County, chlamydia has fallen from 411.6 to 306.4 per 100,000 (26%), gonorrhea has fallen from 163.8 to 67.3 per 100,000 (59%), and P&S syphilis has risen from 7.6 to 30.3 per 100,000 (299%).

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 Mendocino County.
Local HIV snapshot
Mendocino County HIV care continuum (2020)
Mendocino County recorded 6.5 new HIV diagnoses per 100,000 (2020), against 14.9 statewide and 13.7 nationally. Among Mendocino County residents living with HIV, 84% are in care · 71.6% 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 Mendocino County tests for syphilis.

Data & references
Local context
Boonville's rhythm turns on the vineyard calendar and the trades that keep the valley running: pruning seasons, harvest weeks, the steady work of hospitality and skilled labor that draws people in and keeps them rooted. Life here moves fast enough that a health appointment can feel like one more thing to squeeze in, yet health care that respects your privacy shouldn't require a special trip or a cover story. STI testing in and around Boonville, listed on this page, sits within reach of residents who value both efficiency and discretion. The valley draws young adults building careers and households, some establishing roots alongside parents or extended family, others striking out on their own. That mix means different life stages and different reasons to get screened: before a new relationship, as part of routine care, or simply because staying informed feels like basic self-respect.
The clinics and providers serving the area understand that confidentiality isn't negotiable; test results stay sealed between you and your health record, separate from any workplace or family network. Whether you're heading toward The Corners, working the vineyards along CA 128, or living deeper in Bear Wallow, confidential testing is available without fanfare or delay. A straightforward appointment, clear results, and privacy that holds. That's what matters when you're living a full life in a close-knit place.

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.
