Fees & payment
Sierra Family Medical Clinic in Nevada City brings STI testing into a family practice, where appointments connect the standard bacterial and viral panel (gonorrhea, chlamydia, syphilis, HIV, and hepatitis) with sliding-scale fees, same-visit bacterial treatment, and care available in Spanish.
Clinical staff at Sierra Family Medical Clinic conduct STI visits in Spanish, which means the conversation about symptoms, history, and next steps runs in the same language as the answers. Nothing is filtered through a secondary layer before it reaches the provider.
Sierra Family Medical Clinic offers substance-use treatment alongside its STI services, so a patient managing both concerns schedules within one practice rather than coordinating between separate systems. Reducing the friction that often causes one issue to go unaddressed.
Sierra Family Medical Clinic tests for herpes, hepatitis A, hepatitis B, and hepatitis C in addition to the core four: a seven-infection panel that surfaces conditions often missed when a clinic limits its screening to gonorrhea, chlamydia, syphilis, and HIV alone.

STD stats & rates
How reported STI rates in Yuba County, the county that includes Challenge-Brownsville, 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.
#31 of 58 California counties for chlamydia, a higher rate than 47% of the state
| Infection | Yuba County | California | United States |
|---|---|---|---|
| Chlamydia | 324.3 278 cases ▼ 34% | 491.1 | 492.2 |
| Gonorrhea | 108.5 93 cases ▼ 43% | 190.2 | 179.5 |
| Syphilis (P&S) | 16.3 14 cases ≈ the state average | 16.3 | 15.8 |
| Syphilis (early) | 11.7 10 cases ▼ 39% | 19.1 | 16 |
| Syphilis (late/unknown) | 49 42 cases ▲ 5% | 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 Yuba County, chlamydia has fallen from 360.4 to 324.3 per 100,000 (10%), gonorrhea has fallen from 240.3 to 108.5 per 100,000 (55%), and P&S syphilis has fallen from 77.2 to 16.3 per 100,000 (79%).

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 Yuba County.
Local HIV snapshot
Yuba County HIV care continuum (2023)
Yuba County recorded 7.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Yuba County residents living with HIV, 79% are in care · 44.8% 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 Yuba 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.
