Tehama County Health Services Agency in Corning provides STI testing (rapid HIV, syphilis, gonorrhea, chlamydia, and hepatitis C) at no fee, with sliding-scale options and Medicaid and private insurance accepted. Appointments are required, bacterial infections are treated same visit, and hepatitis A and B vaccines are on-site.
When a fee stands between a person and care, the untreated infection is the real outcome. Delayed treatment, ongoing transmission, compounding risk. At Tehama County Health Services Agency, every service carries no charge, so cost never becomes the reason a diagnosis waits.
When care can't be given in a person's own language, misunderstood instructions and missed follow-through are the predictable result. Not a language barrier so much as a care gap. Tehama County Health Services Agency delivers services directly in Spanish, so nothing clinically important gets lost in translation.
For someone managing substance use and facing an STI, Tehama County Health Services Agency holds both tracks. Substance-abuse treatment and full STI care are offered at the same clinic, so addressing one doesn't mean pausing the other.

Ampla Health in Los Molinos runs by appointment, so each visit is structured to cover the full standard panel (HIV, syphilis, gonorrhea, chlamydia) plus treatment for bacterial infections the same day. Fees follow a sliding scale accepted alongside Medicaid, Medicare, and private insurance.
Ampla Health carries Spanish-language care as a native clinical capability, backed by interpretation services for additional languages: meaning documentation, counseling, and treatment discussion all operate without a communication gap. That coverage applies across every service the clinic delivers, not only at intake.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Ampla Health tests for herpes, hepatitis B, and hepatitis C. Infections that a narrower panel would leave undetected. TB testing and treatment are on the same roster, extending the diagnostic scope well past the default four-infection baseline.

STD stats & rates
How reported STI rates in Tehama County, the county that includes Corning, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~31% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#37 of 58 California counties for chlamydia, a higher rate than 36% of the state
| Infection | Tehama County | California | United States |
|---|---|---|---|
| Chlamydia | 300.5 195 cases ▼ 39% | 491.1 | 492.2 |
| Gonorrhea | 86.3 56 cases ▼ 55% | 190.2 | 179.5 |
| Syphilis (P&S) | 26.2 17 cases ▲ 61% | 16.3 | 15.8 |
| Syphilis (early) | 7.7 5 cases ▼ 60% | 19.1 | 16 |
| Syphilis (late/unknown) | 44.7 29 cases ▼ 4% | 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 Tehama County, chlamydia has fallen from 338.8 to 300.5 per 100,000 (11%), gonorrhea has fallen from 151.9 to 86.3 per 100,000 (43%), and P&S syphilis has fallen from 34.9 to 26.2 per 100,000 (25%).

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 Tehama County.
Local HIV snapshot
Tehama County HIV care continuum (2023)
Tehama County recorded 13 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Tehama County residents living with HIV, 73.5% are in care · 40.8% 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 Tehama County tests for syphilis.

Local resources & officials
Data & references
Local context
Northside Park anchors a neighborhood where large households are common and roughly half of residents are renters keeping monthly costs well under a thousand dollars. That financial reality, paired with an unemployment rate that leaves a meaningful share of working-age adults piecing together irregular schedules, shapes how people here think about health appointments: something has to be worth the trip, the time off, and sometimes the co-pay. Corning's younger adults, the late-teens-and-twenties crowd who statistically see the sharpest STI rates, feel that calculation most acutely.
When nearly four in ten households have no six-figure earner and average households run to more than three people, a medical visit that costs little and fits a lunch break or an afternoon gap matters more than it might elsewhere. The options listed on this page span enough variety in fees and hours that most people can find one that doesn't require burning a full work shift or a tank of gas on I-5. That range is what turns a routine screening from a hassle into something a person living here can realistically act on.
Getting there
At 6.53/20 on the EPA walkability index, day-to-day errands in Corning generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
