STD stats & rates

#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
Denton's rhythms run on livestock, grain, and the seasons that shape both. Spring and fall bring the heaviest work; winter settles into a different pace. That steady cycle means health matters, including sexual health, often get crowded out until something shifts. STD testing in and around Denton is available through clinics listed on this page, and the confidentiality built into those visits stands apart from the openness of daily life here.
In a town where many people work across overlapping circles, knowing your status privately matters. Young adults in Denton, those in their late teens through thirties, carry the bulk of new STI diagnoses nationally, yet routine screening still feels like something to schedule later. The clinics serving Denton offer straightforward, judgment-free testing that doesn't require you to navigate explanations afterward or worry about word traveling through town. Results stay confidential; the clinic staff doesn't contact your employer, your family, or anyone else.
Getting tested takes an hour or two and costs far less than letting an infection linger. Whether you're between jobs, managing seasonal work, or juggling multiple responsibilities, clinics listed on this page can fit testing into your actual schedule: early mornings, afternoons, or by appointment. Starting treatment early, if needed, means better outcomes and lower risk of passing infection to partners.

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.
