STD stats & rates
How reported STI rates in Chouteau County, the county that includes Big Sandy, compare with Montana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~24% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#50 of 56 Montana counties for chlamydia, a higher rate than 11% of the state
| Infection | Chouteau County | Montana | United States |
|---|---|---|---|
| Chlamydia | 51.3 3 cases ▼ 84% | 322.6 | 492.2 |
| Gonorrhea | 17.1 1 cases ▼ 75% | 67.7 | 179.5 |
| Syphilis (P&S) | — no data | 27.5 | 15.8 |

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 Chouteau County, chlamydia has risen from 17 to 51.3 per 100,000 (202%), and gonorrhea has risen from 16.9 to 17.1 per 100,000 (1%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Chouteau County.
Local HIV snapshot
Chouteau County HIV care continuum (2023)
Chouteau County recorded 0 new HIV diagnoses per 100,000 (2023), against 3 statewide and 13.7 nationally. 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 Chouteau County tests for syphilis.

Data & references
Local context
Rattlesnake Butte anchors the eastern edge of town the way the old-timers at the Big Sandy Historical Society Museum anchor its stories, steady, unhurried, rooted. The pace here suits the majority of households that own their homes and have lived long enough in Chouteau County to know their neighbors by name. That logistics reality lands unevenly on younger adults: people in their late teens and twenties who are statistically in their highest-risk years for STIs and who may not yet have the flexibility, the vehicle access, or the established routines that make a long trip feel like a minor errand.
A community where most adults are married and households run larger than the national average still contains a meaningful share of people at the life stage where regular screening matters most, and options listed here vary enough in hours and format to match different kinds of weeks. Cost is worth naming plainly. With roughly three in ten residents renting at a relatively modest monthly rate, out-of-pocket fees can still be a real calculation, and the lower-cost and sliding-scale options among the clinics listed here exist precisely for that resident.
Getting there

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.
