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

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 Johnson County tests for syphilis.

Local context

About Buffalo, WY

The Johnson County Courthouse anchors downtown Buffalo the way long-rooted institutions do in small Wyoming towns, steady, familiar, easy to locate on North Main Street. Getting to a clinic is a different matter. That calculation weighs differently depending on how a household is set up. Nearly two in five Buffalo residents rent, and at roughly $888 a month, rent here isn't trivial against a Wyoming wage.

For that share of the population (often younger adults still building financial footing, the very people in their late teens and twenties for whom regular screening matters most) a sliding-scale or low-cost option among the fourteen listed here can be the detail that determines whether a test actually gets scheduled. Workforce participation in Buffalo is solid, which means most adults are working regular hours, and options with evening or weekend availability matter more than they might appear to on paper. For a household earning well under the six-figure threshold that roughly a quarter of Buffalo families reach, free or reduced-fee testing at one of the options listed on this page isn't a convenience. It's the line between a manageable errand and one that gets postponed indefinitely.

Confidentiality & consent in Wyoming

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

Two things that actually depend on Wyoming 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 Wyoming, 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)

Wyoming 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.
