STD stats & rates
How reported STI rates in Contra Costa County, the county that includes Oakley, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#19 of 58 California counties for chlamydia, a higher rate than 67% of the state
| Infection | Contra Costa County | California | United States |
|---|---|---|---|
| Chlamydia | 427.7 4,940 cases ▼ 13% | 491.1 | 492.2 |
| Gonorrhea | 127.9 1,477 cases ▼ 33% | 190.2 | 179.5 |
| Syphilis (P&S) | 13.2 153 cases ▼ 19% | 16.3 | 15.8 |
| Syphilis (early) | 9 104 cases ▼ 53% | 19.1 | 16 |
| Syphilis (late/unknown) | 22.3 257 cases ▼ 52% | 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 Contra Costa County, chlamydia has risen from 386.3 to 427.7 per 100,000 (11%), gonorrhea has fallen from 177.7 to 127.9 per 100,000 (28%), and P&S syphilis has fallen from 15.5 to 13.2 per 100,000 (15%).

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 Contra Costa County.
Local HIV snapshot
Contra Costa County HIV care continuum (2023)
Contra Costa County recorded 12.7 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Contra Costa County residents living with HIV, 80.2% are in care · 73.4% 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 Contra Costa County tests for syphilis.

Data & references
Local context
Oakley Park & Ride sits at the edge of a city where most households own their homes and have done so long enough to put down real roots, which shapes how people think about routine health care here. With large households averaging close to four people and more than half of adults married, a lot of health decisions get made as a family unit, which can be both a support and a delay: a partner's schedule, a kid's carpool, a commute out of Contra Costa County can all quietly eat the window you'd set aside for a clinic visit. That's worth naming because the younger adults in Oakley, people in their late teens through late twenties building relationships and new households, are exactly the group for whom a postponed appointment becomes a month-long gap.
At the same time, over half of Oakley households bring in six figures, yet rents near $1,700 a month mean cost is still real for the quarter of residents who don't own. The clinics serving Sterling Pinnacle and the neighborhoods off Main Street include low- and no-cost options precisely because "affordable" isn't one-size-fits-all even in a relatively prosperous community.
Getting there
At 8.5/20 on the EPA walkability index, day-to-day errands in Oakley 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.
