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 Big Horn County tests for syphilis.

About Greybull, WY

Greybull Avenue cuts through a town where home values stay modest and rents sit well below the national floor, a cost-of-living profile that leaves most households with real financial breathing room, yet one that coexists with an unemployment rate high enough to keep a meaningful share of residents outside the formal workforce entirely. That workforce reality shapes daily schedules in ways that don't always align with standard clinic hours: when income is intermittent or job searches fill the week unpredictably, a routine health appointment can slide for months without anyone making a deliberate choice to skip it. The town leans heavily toward homeowners and married households with larger-than-average family sizes, which can create a misleading sense of settled stability around sexual health.

Young adults in their late teens and twenties are still very much present here, still dating, still forming new relationships, and they're the people for whom a long drive on US 14 to reach the nearest clinic is the most tangible barrier to staying current on screening. Big Horn Basin winters make an already spread-out landscape feel more so, knowing the nearest clinic's hours before January arrives is genuinely practical.

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.
