STD stats & rates
How reported STI rates in Sonoma County, the county that includes Timber Cove, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~18% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#25 of 58 California counties for chlamydia, a higher rate than 57% of the state
| Infection | Sonoma County | California | United States |
|---|---|---|---|
| Chlamydia | 362.6 1,747 cases ▼ 26% | 491.1 | 492.2 |
| Gonorrhea | 103.4 498 cases ▼ 46% | 190.2 | 179.5 |
| Syphilis (P&S) | 14.9 72 cases ▼ 9% | 16.3 | 15.8 |
| Syphilis (early) | 15.8 76 cases ▼ 17% | 19.1 | 16 |
| Syphilis (late/unknown) | 13.5 65 cases ▼ 71% | 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 Sonoma County, chlamydia has risen from 269.2 to 362.6 per 100,000 (35%), gonorrhea has fallen from 131.5 to 103.4 per 100,000 (21%), and P&S syphilis has risen from 13.1 to 14.9 per 100,000 (14%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Sonoma County.
Local HIV snapshot
Sonoma County HIV care continuum (2023)
Sonoma County recorded 9.1 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Sonoma County residents living with HIV, 86.8% are in care · 83.4% 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 Sonoma County tests for syphilis.

Local resources & officials
Data & references
Local context
Pomona's cluster of long-settled households tells part of Timber Cove's story: most residents here own their homes, many are married, and the community skews toward stability in ways that can make a place feel insulated from health concerns that are, in reality, universal. But a fifth of the workforce is currently without a job, and that kind of financial pressure reshapes how people weigh anything that costs time or money. Including a clinic visit. That matters especially for younger adults still establishing themselves along this stretch of the coast.
With CA 1 as the main artery and the nearest options listed here requiring a real drive from Table Mountain and Clam Beach, convenience isn't a given. High unemployment tends to complicate even routine care, not just through cost, but through the particular anxiety of rearranging an already-uncertain schedule. A community where fewer than a quarter of households rent still contains people navigating tight margins, and the under-35 crowd is statistically most likely to benefit from regular, low-threshold screening precisely because that life stage involves the most relationship change.
Getting there
At 4.78/20 on the EPA walkability index, day-to-day errands in Timber Cove 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.
