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.

About Markesan, WI

Winter mornings frost the lawns around Hein Park before the sun clears the treeline, and by spring, residents who've lived here for decades still wave from their porches to neighbors they've known for years. In a town where people tend to stay put and raise families, confidential STI screening can feel like something that belongs elsewhere, but it belongs here too. Young adults moving through their twenties and thirties, whether they've grown up in Markesan or arrived more recently, benefit from the same straightforward access to testing that their peers in larger towns expect. The clinics and providers listed on this page understand that routine screening is ordinary health care, not exceptional or shameful, and they guard what you share with them.

What makes testing in and around Markesan workable is the absence of performance: you go, you're seen, and the results stay private. Many residents have built lives here on modest incomes and long leases; they value affordability and reliability, and the testing available locally reflects that. Whether you're paired or single, whether you're thinking through a relationship change or simply want to know your status, the threshold to get screened is low enough that putting it off makes less sense than following through.

Confidentiality & consent in Wisconsin

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

Two things that actually depend on Wisconsin 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 Wisconsin, 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)

Wisconsin permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.

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.
