NorthBay Health in Vacaville tests for gonorrhea, chlamydia, syphilis, herpes, and HIV on a sliding-scale fee, with PrEP covered for the uninsured and no appointment required. Spanish-language care available throughout.
Herpes screening routinely gets dropped from STI panels at many clinics, leaving patients to seek it separately. NorthBay Health includes it alongside gonorrhea, chlamydia, syphilis, and HIV. One visit covers the full picture rather than leaving a visible gap in the workup.
NorthBay Health prescribes both PrEP and PEP directly, meaning ongoing HIV prevention doesn't require a separate specialist appointment. A patient can move from testing to a prevention prescription within the same clinical relationship.
Many clinics offer a language line as the extent of their Spanish-language support, placing a third party between patient and provider at the moments that matter most. At NorthBay Health, Spanish is a working clinical language: conversations about exposure, treatment, and prevention happen directly, without the delay of a relay.

STD stats & rates
How reported STI rates in Solano County, the county that includes Vacaville, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#14 of 58 California counties for chlamydia, a higher rate than 76% of the state
| Infection | Solano County | California | United States |
|---|---|---|---|
| Chlamydia | 471.9 2,120 cases ▼ 4% | 491.1 | 492.2 |
| Gonorrhea | 137.6 618 cases ▼ 28% | 190.2 | 179.5 |
| Syphilis (P&S) | 24.3 109 cases ▲ 49% | 16.3 | 15.8 |
| Syphilis (early) | 14.9 67 cases ▼ 22% | 19.1 | 16 |

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 Solano County, chlamydia has fallen from 503.4 to 471.9 per 100,000 (6%), gonorrhea has fallen from 222.5 to 137.6 per 100,000 (38%), and P&S syphilis has risen from 14.3 to 24.3 per 100,000 (70%).

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 Solano County.
Local HIV snapshot
Solano County HIV care continuum (2023)
Solano County recorded 15 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Solano County residents living with HIV, 76.1% are in care · 69.7% 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 Solano County tests for syphilis.

Data & references
Local context
Eastbound on Peabody Road past the Shell station at Hume Way, the drive to most clinics listed here runs under fifteen minutes. A real advantage in a city where I-80 can compress or stretch any errand depending on the hour. That kind of short hop matters most to younger adults in their late teens and twenties, who statistically face the steepest STI risk yet often absorb the cost in time and awkwardness most acutely. The household picture here adds texture to that reality.
Nearly two in five residents rent, and at Vacaville's typical monthly rent, budgets run tight enough that an unexpected fee becomes a genuine reason to postpone something. At the same time, a substantial share of households clear six figures annually, so the barrier isn't always money. It's more often the schedule. With a large share of the city employed and household sizes running larger than the California norm, a lot of people are coordinating around kids, partners, and shift times rather than managing a solo calendar.
Leisure Town residents heading up Elmira Road or cutting through to Peabody can reach clinics without setting foot on the freeway. Testing options gives Vacaville something most comparable cities don't: genuine choice. Whether that means a walk-in slot on a Wednesday lunch break or a low-cost appointment that fits a renter's month, the options are there, and Hawkins Park is closer to several of them than most people realize.
Getting there
Vacaville scores 13.31/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
