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 Plumas County, chlamydia has fallen from 207.2 to 146.4 per 100,000 (29%), gonorrhea has fallen from 85.9 to 15.7 per 100,000 (82%), and P&S syphilis has fallen from 15.2 to 10.3 per 100,000 (32%).

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 Plumas County.
Local HIV snapshot
Plumas County HIV care continuum (2023)
Plumas County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Plumas County residents living with HIV, 88% are in care · 76% 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 Plumas County tests for syphilis.

Local resources & officials
Data & references
Local context
CA 36 threads through Chester's modest commercial strip, and the renters clustered along it, roughly a quarter of households, tend to be younger adults still sorting out careers and relationships, paying some of the more affordable rents found anywhere in the Sierra Nevada foothills. That combination of low monthly overhead and a labor market where nearly everyone who wants work has it creates a surface stability, but it also means a lot of people in their late teens and twenties are quietly mobile: new to town, new to partners, and not necessarily plugged into local health resources. Chester skews toward settled households, married-couple families with a typical size above two and a half, which shapes what "normal" looks like here. But that majority-owner, majority-married picture doesn't erase the significant share of residents who are younger, renting, and navigating the relationship years when routine screening matters most.
Chester Park and the CA 36 corridor are pleasant to walk on a summer afternoon, but getting to a clinic is a different proposition entirely. Chester's below-average scores aren't a technicality, they mean a car trip, often a real one, to reach the options listed on this page. Knowing that ahead of time lets people plan around it rather than be surprised by it, which is often what actually gets the appointment booked.
Getting there
Chester scores 11.28/20 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.

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.
