Herpes and Hepatitis Testing Alongside the Standard Panel

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.

Non-English Care Without a Gap in the Conversation

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. Horizon Health Care in De Smet provides interpretation services for non-English languages, keeping the full weight of the clinical conversation intact from intake through treatment.

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.

Confidentiality & consent in South Dakota

Minor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

In South Dakota, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.

Can my partner be treated too? (EPT)

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.
