STD stats & rates
How reported STI rates in Yuba County, the county that includes Marysville, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~30% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#31 of 58 California counties for chlamydia, a higher rate than 47% of the state
| Infection | Yuba County | California | United States |
|---|---|---|---|
| Chlamydia | 324.3 278 cases ▼ 34% | 491.1 | 492.2 |
| Gonorrhea | 108.5 93 cases ▼ 43% | 190.2 | 179.5 |
| Syphilis (P&S) | 16.3 14 cases ≈ the state average | 16.3 | 15.8 |
| Syphilis (early) | 11.7 10 cases ▼ 39% | 19.1 | 16 |
| Syphilis (late/unknown) | 49 42 cases ▲ 5% | 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 Yuba County, chlamydia has fallen from 360.4 to 324.3 per 100,000 (10%), gonorrhea has fallen from 240.3 to 108.5 per 100,000 (55%), and P&S syphilis has fallen from 77.2 to 16.3 per 100,000 (79%).

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 Yuba County.
Local HIV snapshot
Yuba County HIV care continuum (2023)
Yuba County recorded 7.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Yuba County residents living with HIV, 79% are in care · 44.8% 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 Yuba County tests for syphilis.

Local resources & officials
Data & references
Local context
Linda is a neighborhood where renters outnumber owners and households tend to run large, and many of the adults there are working schedules that leave little room for midday appointments. That workforce picture, where more than four in ten residents are outside the labor force entirely and unemployment runs meaningfully above national norms, means that when someone does have working hours, a testing appointment can feel like it competes directly with shifts, childcare, or a second job. For young adults in Marysville, those in their late teens and twenties who represent nearly three in ten residents, that scheduling squeeze is exactly why having a spread of accessible options matters rather than a single distant clinic.
The rent levels here are modest by California standards, which helps explain why cost-sensitivity shapes how people engage with healthcare. A visit that costs nothing, or close to it, lands very differently for a renter in Linda or near East Ellis Lake than one that requires upfront payment. That range is what turns the listings from a reference into an actual plan.
Getting there
Marysville scores 12.45/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
