Tests offered
MACT Health Board in San Andreas covers gonorrhea, chlamydia, syphilis, HIV, hepatitis C, and TB on a sliding-scale fee accepted alongside Medicaid, Medicare, and private insurance. Appointments are required, bacterial infections treated same visit, and vaccines for HPV, hepatitis A, and hepatitis B are available.
Standalone STI clinics rarely hold a substance-use treatment program, those referrals typically go somewhere else entirely. At MACT Health Board, both services live within the same organization, so a visit that starts with a syphilis test can also open a door to addiction care without routing you to a separate provider.
The four-infection panel (HIV, syphilis, gonorrhea, chlamydia) is where many clinics stop. MACT Health Board extends testing to hepatitis C as well, and with on-site hepatitis A and B vaccination available, the full picture of hepatitis exposure and prevention is handled in a single setting.

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 Calaveras County, chlamydia has risen from 17.7 to 100.9 per 100,000 (470%), gonorrhea has fallen from 66.2 to 30.1 per 100,000 (55%), and P&S syphilis has risen from 2.2 to 4.3 per 100,000 (95%).

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 Calaveras County.
Local HIV snapshot
Calaveras County HIV care continuum (2022)
Calaveras County recorded 0 new HIV diagnoses per 100,000 (2022), against 14.9 statewide and 13.7 nationally. Among Calaveras County residents living with HIV, 77.6% are in care · 57.1% 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 Calaveras County tests for syphilis.

Data & references
Local context
Fort Mountain anchors the eastern edge of Rail Road Flat's geography, and the community that lives in its shadow is one where most households own their homes and well over half of adults are married. Conditions that tend to push health decisions toward the practical and the shared rather than the spontaneous. When a couple or a family weighs a medical errand, it often comes down to schedules, distance, and what the week actually allows. Both of those factors press hard here. Labor-force participation is low and unemployment is notably high, which sounds like it should free up time, but irregular work and stretched budgets have a way of making a long drive feel like a luxury.
For younger adults still forming relationships (the group most likely to encounter chlamydia, gonorrhea, or the other infections Calaveras County tracks) that planning step is often the whole obstacle. Calaveras County's STI figures reflect a place where transmission doesn't announce itself loudly, which is precisely why staying current matters. For someone whose nearest testing option is a real drive away, a routine check isn't a minor errand. It's the kind of thing that works best when it's already on the calendar before a reason appears.
Getting there

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.
