STD stats & rates
How reported STI rates in Colusa County, the county that includes College City, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#44 of 58 California counties for chlamydia, a higher rate than 24% of the state
| Infection | Colusa County | California | United States |
|---|---|---|---|
| Chlamydia | 249.6 55 cases ▼ 49% | 491.1 | 492.2 |
| Gonorrhea | 49.9 11 cases ▼ 74% | 190.2 | 179.5 |
| Syphilis (P&S) | 18.2 4 cases ▲ 12% | 16.3 | 15.8 |
| Syphilis (early) | 9.1 2 cases ▼ 52% | 19.1 | 16 |
| Syphilis (late/unknown) | 18.2 4 cases ▼ 61% | 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 Colusa County, chlamydia has risen from 238.1 to 249.6 per 100,000 (5%), gonorrhea has fallen from 114.5 to 49.9 per 100,000 (56%), and P&S syphilis has risen from 9.2 to 18.2 per 100,000 (98%).

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 Colusa County.
Local HIV snapshot
Colusa County HIV care continuum (2023)
Among Colusa County residents living with HIV, 85% are in care · 45% 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 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 Colusa County tests for syphilis.

Data & references
Local context
Getting tested in College City means working with what's actually here: clinics and urgent care nearby, but nothing that feels abundant. The young adult population, late teens through their thirties, makes up a genuine presence in town, and for that group especially, STI screening fits into the practical rhythm of staying healthy without fanfare. Testing services listed on this page cluster within or just beyond College City's reach, accessible enough that distance alone doesn't become the reason to skip it. What matters most here is that screening happens quietly.
A positive result doesn't ripple through a small-town grapevine; a negative one stays yours alone. That privacy isn't incidental, it's the foundation that makes people actually show up. Whether you're between jobs, settled into work, or managing school and other obligations, the ability to get tested without broadcast shapes whether you actually do it. The clinics and providers serving College City understand that routine screening is ordinary preventive care, not crisis intervention.
Walk in with a question, get an answer, and move forward. That straightforwardness, the absence of drama or judgment, is what turns testing from something people avoid into something they simply do.
Getting there
At 6.71/20 on the EPA walkability index, day-to-day errands in College City 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.
