Davis Sexual Health Clinic, DaSH, operates on a sliding-scale fee structure, accepts Medicaid and most insurance, and tests for HIV (rapid), gonorrhea, chlamydia, and syphilis with same-visit treatment for bacterial infections; walk-ins are welcome and Spanish is spoken on-site.
DaSH carries Spanish-language capacity directly within the clinic and extends interpretation services to other languages, a standing resource that matters for anyone who navigates medical decisions in a language other than English. Health history, dosing instructions, and prevention counseling land in full rather than filtered.
DaSH prescribes DoxyPEP, doxycycline taken after a potential bacterial STI exposure, alongside both PrEP and PEP, covering the full current range of biomedical HIV and bacterial STI prevention tools. Uninsured patients have a dedicated pathway for PrEP access, and HIV medical management is handled on-site.

CommuniCare OLE in Davis runs on a sliding scale accepting Medicaid, Medicare, and private insurance, with donations accepted for those who prefer that route. Walk-ins are welcome for HIV, syphilis, gonorrhea, chlamydia, and herpes testing, with same-visit treatment for bacterial infections and full care delivered in Spanish.
CommuniCare OLE conducts testing, results, counseling, and treatment entirely in Spanish. Not through an add-on service, but as the operational language of care. That means clinical conversations about PrEP, TB, and STI treatment happen with the same fluency and depth as any other visit at the clinic.
Many STI testing sites hand off prevention prescribing to primary care or infectious disease practices. CommuniCare OLE writes and manages both PrEP and PEP in-house, so prevention doesn't require a separate provider relationship or a second appointment elsewhere.
Substance-use treatment is available at CommuniCare OLE alongside STI testing and care, which means a patient managing both concerns doesn't need to coordinate between separate clinics or providers to keep either thread of treatment on track.

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.

Winters Healthcare in Winters runs on a sliding scale, accepts Medicaid, Medicare, and most insurance, with fees adjusted to income for everyone. The clinic tests for gonorrhea, chlamydia, syphilis, herpes, and HIV by appointment, with same-visit treatment for bacterial infections and care delivered in Spanish.
Clinics running the basic panel stop at gonorrhea, chlamydia, syphilis, and HIV. Herpes goes unasked and untested. Winters Healthcare adds herpes to its panel, closing a gap that otherwise leaves a common infection invisible and unmanaged.
Winters Healthcare prescribes PrEP and PEP directly, and carries a dedicated coverage pathway for uninsured patients. Meaning the medication itself doesn't become a separate financial obstacle after the visit. PEP is also available for post-exposure prevention alongside ongoing PrEP management.
When STI care requires a follow-up appointment at a second site to get answers in Spanish, infections go unaddressed and treatment stalls. Winters Healthcare delivers full STI care in Spanish (diagnosis, treatment decisions, and prevention counseling) without the gap that a referral step creates.

STD stats & rates
How reported STI rates in Solano County, the county that includes Dixon, 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.
#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 |
| Syphilis (late/unknown) | 46.3 208 cases ▼ 1% | 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 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.

Local resources & officials
Data & references
Local context
Hall Memorial Park anchors a neighborhood where most households are owner-occupied, families run larger than the California norm, and more than half of adult residents are married. That settled, rooted character shapes daily life in ways that matter for health care access: when two working adults share a household and children are in the picture, carving out time for a personal medical appointment often loses out to school pickups, work shifts, and the commute onto I-80 toward Sacramento or the Bay Area. With roughly seven in ten residents participating in the labor force, the rhythms here are busy ones.
That schedule pressure lands hardest on people in their late teens and twenties, a group that runs to nearly a third of Dixon's population and accounts for the sharpest concentration of new STI diagnoses statewide. Solano County's own rate data, visible elsewhere on this page, underscores that this isn't an abstract risk. Rent near $1,400 a month means cost is a real calculation too, and free or sliding-scale options among the listings here carry genuine weight for younger adults still building financial footing.
Getting there
At 8.74/20 on the EPA walkability index, day-to-day errands in Dixon 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.
