STD stats & rates
How reported STI rates in Napa County, the county that includes Silverado Resort, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~7% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#43 of 58 California counties for chlamydia, a higher rate than 26% of the state
| Infection | Napa County | California | United States |
|---|---|---|---|
| Chlamydia | 256.7 342 cases ▼ 48% | 491.1 | 492.2 |
| Gonorrhea | 91.6 122 cases ▼ 52% | 190.2 | 179.5 |
| Syphilis (P&S) | 17.3 23 cases ▲ 6% | 16.3 | 15.8 |
| Syphilis (early) | 9.8 13 cases ▼ 49% | 19.1 | 16 |
| Syphilis (late/unknown) | 29.3 39 cases ▼ 37% | 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 Napa County, chlamydia has fallen from 310.8 to 256.7 per 100,000 (17%), gonorrhea has risen from 81.9 to 91.6 per 100,000 (12%), and P&S syphilis has risen from 9.4 to 17.3 per 100,000 (84%).

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 Napa County.
Local HIV snapshot
Napa County HIV care continuum (2023)
Napa County recorded 8.6 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Napa County residents living with HIV, 82.5% are in care · 75.8% 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 Napa County tests for syphilis.

Local resources & officials
Data & references
Local context
Silverado Resort's Vintage District sits where property values rival anything along Napa Valley's celebrated corridors, and most households here are owner-occupied, long-settled, and married, which shapes the rhythm of daily life in ways that quietly affect health routines. With nearly three in four households clearing six figures and a labor-force participation rate that hovers well below the national norm, a substantial portion of residents are retired or semi-retired, meaning their calendars look very different from those of someone clocking in five days a week. The small share of young adults in their late teens and twenties is, by most national patterns, the cohort where new STI diagnoses concentrate, and in a community this size, that group can go without easy access simply because local services are sparse and the culture skews toward established households with long-standing primary-care relationships.
For a resident near the Noyes Mansion, that drive is real, and planning around it matters. What the range of listed options makes possible is a genuine choice: urgent-care-style walk-ins, scheduled appointments, and fee-varied sites, so someone traveling Silverado Trail from any corner of this community can match the format to what their week actually allows.
Getting there
At 8.16/20 on the EPA walkability index, day-to-day errands in Silverado Resort 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.
