STD stats & rates
How reported STI rates in Fergus County, the county that includes Grass Range, compare with Montana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~8% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#38 of 56 Montana counties for chlamydia, a higher rate than 32% of the state
| Infection | Fergus County | Montana | United States |
|---|---|---|---|
| Chlamydia | 110.4 13 cases ▼ 66% | 322.6 | 492.2 |
| Gonorrhea | 34 4 cases ▼ 50% | 67.7 | 179.5 |
| Syphilis (P&S) | 8.5 1 cases ▼ 69% | 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 Fergus County, chlamydia has fallen from 192.2 to 110.4 per 100,000 (43%), gonorrhea has fallen from 34.9 to 34 per 100,000 (3%), and P&S syphilis has held roughly steady from 8.5 to 8.5 per 100,000.
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 Fergus County.
Local HIV snapshot
Fergus County HIV care continuum (2023)
Fergus County recorded 0 new HIV diagnoses per 100,000 (2023), against 3 statewide and 13.7 nationally. Among Fergus County residents living with HIV, 100% are in care · 100% 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 Fergus County tests for syphilis.

Data & references
Local context
Grass Range City Park anchors a community where most adults own their homes and have for years: the kind of place where households run large, neighbors know each other's names, and the rhythm of daily life is shaped more by ranching schedules and seasonal work than by a nine-to-five clock. That rooted quality is real, but it also means the smaller slice of younger adults here (people in their late teens and twenties who are renting, dating, and sorting out what regular healthcare even looks like for them) can find themselves without an obvious, low-effort path to routine screening.
Rent here is modest by any measure, which eases one common barrier, and a labor force built around demanding physical work means time off for a clinic visit has to be planned deliberately rather than grabbed on a lunch break. The options listed on this page involve a real drive out of Fergus County's rural stretch, which means the logistics (gas, a half-day away from work or home) are the actual variable that determines whether screening happens this month or gets quietly postponed into next season.
Getting there
At 5.52/20 on the EPA walkability index, day-to-day errands in Grass Range generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
