Fees & payment
Horizon Health Care in De Smet anchors STI care within a full-service community health model, covering gonorrhea, chlamydia, syphilis, and HIV on a sliding-scale fee with same-visit bacterial treatment; HPV, hepatitis A, and hepatitis B vaccines are also available, and appointments are required.
Plenty of STI clinics test for the four bacterial and viral basics and stop there, leaving herpes and hepatitis A, B, and C to separate referrals. Horizon Health Care in De Smet tests for all of them in one visit, so a fuller picture of your sexual health doesn't depend on chasing down additional appointments elsewhere.
When a language barrier goes unaddressed at an STI clinic, the real cost is clinical: nuances in symptom history get lost, treatment instructions don't land clearly, and follow-through suffers.

STD stats & rates
How reported STI rates in Kingsbury County, the county that includes Lake Preston, compare with South Dakota and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#48 of 66 South Dakota counties for chlamydia, a higher rate than 27% of the state
| Infection | Kingsbury County | South Dakota | United States |
|---|---|---|---|
| Chlamydia | 151.6 8 cases ▼ 71% | 531.6 | 492.2 |
| Gonorrhea | — no data | 253.3 | 179.5 |
| Syphilis (P&S) | 37.9 2 cases ▼ 48% | 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 Kingsbury County, chlamydia has risen from 135 to 151.6 per 100,000 (12%), gonorrhea has fallen from 38.6 to 38.5 per 100,000 (0%), and P&S syphilis has held roughly steady from 37.9 to 37.9 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 Kingsbury County.
Local HIV snapshot
Kingsbury County HIV care continuum (2023)
Kingsbury 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 Kingsbury County tests for syphilis.

Data & references
Local context
Winter wind across the lake sharpens the air here, and so does the clarity that comes with knowing your sexual health status. Something straightforward to arrange without fanfare. Lake Preston's mix of young adults means routine STI screening is woven into ordinary preventive care, not a crisis response. Testing in and around Lake Preston listed on this page can be scheduled discreetly; results stay confidential, and the process itself is quick enough to fit into a regular Tuesday or lunch break. The town sits at the crossroads where US 14 passes through, connecting residents to services both locally and in nearby communities.
That geography means you're not isolated when seeking a test: clinics within reach understand that sexual health screening is as unremarkable as any other checkup, and they keep your information private as a matter of course. Young people here (whether they've just moved to the area, are between relationships, or simply want baseline clarity) find that getting tested carries no judgment and requires no elaborate explanation. Confidentiality isn't performance; it's standard practice. Knowing your status is the practical choice, and Lake Preston's testing services treat it that way.
Getting there

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.
