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 Sioux County, chlamydia has risen from 1847.1 to 1894 per 100,000 (3%), gonorrhea has fallen from 1513.6 to 1290.1 per 100,000 (15%), and P&S syphilis has risen from 134.7 to 521.5 per 100,000 (287%).

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 Sioux County.
Local HIV snapshot
Sioux County HIV care continuum (2023)
Sioux County recorded 0 new HIV diagnoses per 100,000 (2023), against 3.2 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 Sioux County tests for syphilis.

Data & references
Local context
Selfridge's older residential streets, modest homes that have traded hands within the same families for decades, tell you something real about how this community is structured. Homeownership here runs unusually high, which means most households carry the stability of a fixed address, low monthly housing costs, and neighbors who recognize each other by name. Rents sit well below the state average, which sounds like breathing room until you realize that a workforce participation rate closer to half the adult population than the full one means many households are managing on a single income, or on retirement fixed-income, or on part-time work, and that a doctor visit still competes with everything else on a tight month.
The share of younger adults (people in their late teens and twenties who are statistically at the highest risk for chlamydia, gonorrhea, and other STIs) is smaller here than in college towns, but that doesn't shrink individual risk. What it does mean is that younger residents often feel more visible, more known, which can make seeking out testing feel complicated in ways that have nothing to do with logistics. The clinics listed above span different hours and cost structures precisely because one format won't reach everyone here, and in a community this connected, word spreads when a place treats people decently.
Getting there
At 4.14/20 on the EPA walkability index, day-to-day errands in Selfridge 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 North Dakota 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 North Dakota, a minor aged 14 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
North Dakota 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.
