A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Horizon Health Care in Howard tests for gonorrhea, syphilis, chlamydia, HIV, herpes, and hepatitis A, B, and C on a sliding-scale fee accepted by Medicaid, Medicare, and most insurance. Bacterial STIs are treated the same visit; an appointment is required.
Leaving herpes or hepatitis untested means a separate appointment elsewhere, another fee, another wait, another chance the result never gets acted on. Horizon Health Care's panel covers herpes alongside hepatitis A, B, and C, so a single visit to Howard closes those gaps rather than deferring them.
Without on-site interpretation, a missed nuance in a test explanation or a treatment instruction becomes a real clinical risk. Not an inconvenience. Horizon Health Care in Howard has interpretation services available for non-English languages, keeping every part of your care accurate from the conversation forward.

STD stats & rates
How reported STI rates in Lake County, the county that includes Madison, compare with South Dakota and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~30% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#35 of 66 South Dakota counties for chlamydia, a higher rate than 47% of the state
| Infection | Lake County | South Dakota | United States |
|---|---|---|---|
| Chlamydia | 253.8 28 cases ▼ 52% | 531.6 | 492.2 |
| Gonorrhea | 36.3 4 cases ▼ 86% | 253.3 | 179.5 |
| Syphilis (P&S) | — no data | 73.4 | 15.8 |
| Syphilis (early) | — no data | 76.8 | 16 |

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 Lake County, chlamydia has fallen from 361.7 to 253.8 per 100,000 (30%), gonorrhea has fallen from 45.2 to 36.3 per 100,000 (20%), and P&S syphilis has held roughly steady from 18.2 to 18.2 per 100,000.

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 Lake County.
Local HIV snapshot
Lake County HIV care continuum (2023)
Lake 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 Lake County tests for syphilis.

Data & references
Local context
Madison draws young adults for its affordable housing and steadier job prospects in agriculture, healthcare, and small manufacturing. The kind of work that pays enough to build on. The town's larger households often span generations under one roof, which can make privacy feel like something you have to plan for. STD testing in and around Madison is listed on this page through clinics and providers who understand that confidentiality isn't negotiable: what you discuss during a visit stays contained, and results don't circulate through town gossip or workplace networks.
The modest cost of living that makes Madison livable also means health services are designed to fit tight budgets. Testing is straightforward and accessible, whether you're between jobs, managing a shift schedule, or juggling family responsibilities. The clinics available locally handle routine screening without fanfare: they're accustomed to young adults who need quick, discreet care and want to know their status without delay. If you're new to the area or reconnecting after time away, getting tested is a practical first step, not a crisis response.
Many people in Madison do it as part of staying healthy, the same way they'd schedule any other checkup. The providers listed here have built their practices on the understanding that people have real reasons for wanting anonymity and speed, and they deliver both.

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.
