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

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.

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.

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.

STD stats & rates
How reported STI rates in Yolo County, the county that includes Winters, 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.
#20 of 58 California counties for chlamydia, a higher rate than 66% of the state
| Infection | Yolo County | California | United States |
|---|---|---|---|
| Chlamydia | 416.7 919 cases ▼ 15% | 491.1 | 492.2 |
| Gonorrhea | 101.6 224 cases ▼ 47% | 190.2 | 179.5 |
| Syphilis (P&S) | 11.3 25 cases ▼ 31% | 16.3 | 15.8 |
| Syphilis (early) | 5.4 12 cases ▼ 72% | 19.1 | 16 |
| Syphilis (late/unknown) | 31.3 69 cases ▼ 33% | 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 Yolo County, chlamydia has risen from 409.4 to 416.7 per 100,000 (2%), gonorrhea has fallen from 142.8 to 101.6 per 100,000 (29%), and P&S syphilis has fallen from 15.2 to 11.3 per 100,000 (26%).

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 Yolo County.
Local HIV snapshot
Yolo County HIV care continuum (2023)
Yolo County recorded 11.5 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Yolo County residents living with HIV, 79.4% are in care · 71.3% 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 Yolo County tests for syphilis.

Data & references
Local context
Along Valley Oak Park's shaded pathways, family decisions unfold in a community where homeownership is a norm, with many residents putting down roots in spacious homes with ample room for their families. The average household size is substantial, reflecting a community that values family and togetherness. Here, married couples make up nearly half of the households, and many families have multiple generations living together.
Residents of Winters balance work and family life, with many juggling busy schedules to make ends meet. Labor-force participation is high, and a significant portion of households earn a comfortable income, allowing them to enjoy the local amenities, from City Park to Walnut Park. However, with a notable share of renters facing typical rents and a smaller but significant share of residents dealing with unemployment, financial stress can be a reality. Young adults still forming relationships and building their careers are a significant part of the community, and their busy lives can make it challenging to prioritize health screenings.
As residents navigate their daily lives, from Blue Oak Park to the town's commercial areas, staying current with health check-ups can easily take a backseat. In Yolo County, the local health landscape presents specific challenges, particularly for younger adults who are often balancing multiple priorities. With many households having a substantial income and a comfortable lifestyle, it is essential for residents to make informed decisions about their health and well-being, and taking care of one's health can be as simple as taking advantage of the testing options available in and around Winters.

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.
