#43 of 66 South Dakota counties for chlamydia, a higher rate than 35% of the state
| Infection | Clark County | South Dakota | United States |
|---|---|---|---|
| Chlamydia | 177.3 7 cases ▼ 67% | 531.6 | 492.2 |
| Gonorrhea | 25.3 1 cases ▼ 90% | 253.3 | 179.5 |
| Syphilis (P&S) | — no data | 73.4 | 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 Clark County, chlamydia has risen from 78.2 to 177.3 per 100,000 (127%), and gonorrhea has fallen from 52.1 to 25.3 per 100,000 (51%).
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 Clark County.
Local HIV snapshot
Clark County HIV care continuum (2023)
Clark 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 Clark County tests for syphilis.

Local resources & officials
Data & references
Local context
People drift to Clark for the steady work: grain elevators, small manufacturing, the kind of jobs where you can actually afford to rent or buy. US Highway 212 bisects the town, and most folks who land here stay, building lives around the affordable housing and the predictability that comes with it. That stability matters, especially when you're navigating health decisions that feel private in a place where faces repeat. Young adults in their late teens through thirties make up a real presence in Clark, and many of them are at the age when routine STI screening fits naturally into regular health care.
The clinics and providers listed on this page offer testing in and around Clark with the kind of discretion you'd expect from a health system built on trust rather than turnover, staff who work here year after year, not rotating through. What sets testing in Clark apart is the absence of performance. You're not managing visibility the way you might in a place where anonymity is the default. The confidentiality here isn't a selling point because it's simply how the work gets done: your results stay with your provider, your health decisions stay yours, and the person drawing your blood sees you as one more person tending to their own care.
Getting there
At 5.8/20 on the EPA walkability index, day-to-day errands in Clark 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 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.
