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.

Congenital syphilis is the fastest-rising STI: what to test, and when

It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Green Lake County tests for syphilis.

Local context

About Princeton, WI

Driving down West Main Street, residents know that getting to a clinic can take some planning. Many locals own their homes, with nearly two-thirds putting down roots in the community. For those who rent, the typical monthly payment is a significant expense.

The town has a strong sense of community, with almost half of adults married and families making up a substantial part of the population. Homes here tend to be filled with people, with an average of nearly three people per household. While some households earn a higher income, many more are likely to be managing the demands of work and family. People in their late teens and twenties are forming relationships and building their lives, and low-friction access to screening can make a difference for them.

Heistand Park and Old Mill Park offer peaceful escapes from daily life, but for those with busy schedules, finding time for health checks can be a challenge. In this community, where labor-force participation is a significant factor in many households, making time for a health check can be hard. Still, taking care of one's health is essential, especially for young adults still forming relationships, and the options listed here can help.

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.
