STD stats & rates
How reported STI rates in Sanders County, the county that includes Belknap, compare with Montana and U.S. averages, based on the most recent 2023 surveillance data.
#37 of 56 Montana counties for chlamydia, a higher rate than 34% of the state
| Infection | Sanders County | Montana | United States |
|---|---|---|---|
| Chlamydia | 138.8 19 cases ▼ 57% | 322.6 | 492.2 |
| Gonorrhea | 14.6 2 cases ▼ 78% | 67.7 | 179.5 |
| Syphilis (P&S) | 7.3 1 cases ▼ 73% | 27.5 | 15.8 |

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 Sanders County, chlamydia has risen from 112.9 to 138.8 per 100,000 (23%), gonorrhea has fallen from 40.3 to 14.6 per 100,000 (64%), and P&S syphilis has fallen from 8.1 to 7.3 per 100,000 (10%).

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 Sanders County.
Local HIV snapshot
Sanders County HIV care continuum (2023)
Sanders County recorded 0 new HIV diagnoses per 100,000 (2023), against 3 statewide and 13.7 nationally. Among Sanders County residents living with HIV, 100% are in care · 90% 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 Sanders County tests for syphilis.

Data & references
Local context
Belknap looks settled on the surface: most households here own their homes outright, and that kind of rootedness brings real community stability. But the same factors that make this a quiet, ownership-heavy place tucked below Thompson Falls State Recreation Area also mean that getting tested requires actual planning: there's no walking to a clinic between errands, no bus to flag down. Every appointment is a car trip, sometimes a long one, and that changes the calculus for anyone with a packed schedule. That calculus matters most for people in their late teens and twenties, the years when STI risk is statistically sharpest and when a test that requires an hour of driving can easily slip down the week's list of priorities.
With nearly half of Belknap households out of the labor force entirely, and those who do work often juggling non-standard hours, clinic windows that don't flex can be a genuine obstacle. The dozen testing options listed on this page exist precisely to spread out that geography and those hours into something workable. The high homeownership rate also means many residents have lived here long enough to have a primary-care relationship, but a trusted doctor isn't always the most comfortable place to raise sexual health. Options that offer a bit more anonymity, listed among the clinics here, sit alongside the familiar routes between The Rock Hill and Power Park for anyone ready to act.
Getting there
At 5.53/20 on the EPA walkability index, day-to-day errands in Belknap 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 Montana 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 Montana, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Montana 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.
