#42 of 58 California counties for chlamydia, a higher rate than 28% of the state

|---|---|---|---|

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 Mono County, chlamydia has risen from 227.4 to 267.9 per 100,000 (18%), gonorrhea has fallen from 22.7 to 15.3 per 100,000 (33%), and P&S syphilis has fallen from 15.4 to 7.7 per 100,000 (50%).

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 Mono County.
Local HIV snapshot
Mono County HIV care continuum (2023)
Mono County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Mono County residents living with HIV, 90% are in care · 80% 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 Mono County tests for syphilis.

Data & references
Local context
CA 203 cuts straight through town past Mammoth Creek Park West, and on a powder day the drive toward any clinic can stretch well beyond what the map suggests. A reality that shapes how easily anyone fits a screening appointment into a week here. Most residents are renters in a resort economy, paying market-rate rent in a place where nearly everyone who can work does, and that combination leaves little slack in a schedule already built around seasonal shifts and split days off.
That rhythm matters most for younger adults still forming relationships, the late-teen and twenties crowd that makes up a meaningful share of Mammoth Lakes' population and accounts for the bulk of new STI diagnoses statewide. Household sizes here run large, closer to four or five people sharing a place, and with more than half the town renting, health costs land differently than they would in an ownership-heavy community. The range of clinics on this page includes low- and no-cost options precisely because the economics of a resort town like this one don't leave everyone with the same cushion when an unexpected bill arrives.
Getting there
At 6.35/20 on the EPA walkability index, day-to-day errands in Mammoth Lakes 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.
