STD stats & rates
How reported STI rates in McCook County, the county that includes Spencer, compare with South Dakota and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~12% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#47 of 66 South Dakota counties for chlamydia, a higher rate than 29% of the state
| Infection | McCook County | South Dakota | United States |
|---|---|---|---|
| Chlamydia | 154.9 9 cases ▼ 71% | 531.6 | 492.2 |
| Gonorrhea | 34.4 2 cases ▼ 86% | 253.3 | 179.5 |
| Syphilis (P&S) | 17.2 1 cases ▼ 77% | 73.4 | 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 McCook County, chlamydia has fallen from 176 to 154.9 per 100,000 (12%), gonorrhea has fallen from 105.6 to 34.4 per 100,000 (67%), and P&S syphilis has fallen from 17.6 to 17.2 per 100,000 (2%).

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 McCook County.
Local HIV snapshot
McCook County HIV care continuum (2023)
McCook County recorded 0 new HIV diagnoses per 100,000 (2023), against 6.8 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 McCook County tests for syphilis.

Two things that actually depend on South 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 South Dakota, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Expedited Partner Therapy (EPT) is potentially allowable in South Dakota: it is not expressly authorized, but not prohibited either. Ask your provider whether they will prescribe treatment for a partner without a separate visit.
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.
