A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Tests offered
Mountain Valleys Health Centers in Burney tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding-scale fee accepted by Medicaid, Medicare, and most insurance. Appointments are required, and bacterial STIs are treated the same visit. Care is delivered in Spanish.
The panel at Mountain Valleys Health Centers includes herpes alongside gonorrhea, chlamydia, syphilis, and HIV. infections rather than four. That fifth test matters because herpes screening is what clinicians use to distinguish active infection from asymptomatic shedding, informing treatment decisions that a narrower panel simply cannot support.
Mountain Valleys Health Centers offers substance-use treatment as a standing service alongside STI care, which means a patient managing both doesn't lose ground on one while addressing the other. Continuity between the two programs supports medication adherence across the board.
Spanish-language care at Mountain Valleys Health Centers is delivered directly: meaning clinical conversations, counseling, and medication education happen in Spanish through the staff providing the care. Treatment plans, adherence guidance, and STI prevention education are all conducted without a language gap in the clinical exchange itself.

STD stats & rates
How reported STI rates in Shasta County, the county that includes Cassel, compare with California and U.S. averages, based on the most recent 2023 surveillance data.
#40 of 58 California counties for chlamydia, a higher rate than 31% of the state
| Infection | Shasta County | California | United States |
|---|---|---|---|
| Chlamydia | 287.2 518 cases ▼ 42% | 491.1 | 492.2 |
| Gonorrhea | 100.4 181 cases ▼ 47% | 190.2 | 179.5 |
| Syphilis (P&S) | 42.1 76 cases ▲ 158% | 16.3 | 15.8 |
| Syphilis (early) | 9.4 17 cases ▼ 51% | 19.1 | 16 |
| Syphilis (late/unknown) | 29.4 53 cases ▼ 37% | 46.7 | 29.5 |
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 Shasta County, chlamydia has fallen from 347 to 287.2 per 100,000 (17%), gonorrhea has fallen from 203.7 to 100.4 per 100,000 (51%), and P&S syphilis has fallen from 59.8 to 42.1 per 100,000 (30%).

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 Shasta County.
Local HIV snapshot
Shasta County HIV care continuum (2023)
Shasta County recorded 7.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Shasta County residents living with HIV, 86% are in care · 75.4% 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 Shasta County tests for syphilis.

Data & references
Local context
Renting in Cassel is relatively rare, with most residents owning their homes and a lower proportion of the population under 35 than many California communities, the town has a settled, rooted feel. But that younger slice of the population is exactly where new relationships, first-time living arrangements, and shifting insurance coverage tend to land at once, making routine screening easy to let slide without meaning to. Nearly three in eight households here earn above six figures, and unemployment sits remarkably low, yet a high share of residents aren't in the active workforce at all. Suggesting schedules that don't always follow a predictable nine-to-five, which can cut either way when it comes to finding time for a clinic visit.
What does cut clearly one direction is geography. Getting tested means planning a trip, and the options listed on this page exist precisely because that planning shouldn't have to be complicated. Shasta County's STI picture makes access worth the effort. For younger adults still sorting out who their primary-care provider even is, a listed clinic with clear hours and fees removes the part that usually stops people: not knowing where to start.
Getting there
At 5.4/20 on the EPA walkability index, day-to-day errands in Cassel generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
