STDs & HIV in Columbia County: the local picture

How reported STI rates in Columbia County, the county that includes Dayton, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.

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 Columbia County tests for syphilis.

About Dayton, WA

Caboose Park anchors the quieter, residential side of Dayton the same way US 12 anchors its geography: a single corridor threading through a town where most households are owned, most adults are married, and life moves at a pace that can make a clinic appointment feel like something to schedule around everything else rather than alongside it. With labor-force participation notably below half the adult population and the nearest testing options a real drive from this corner of Columbia County, the logistics of getting screened carry genuine weight here. That weight lands unevenly on younger adults still sorting out relationships, jobs, and coverage.

Precisely the years when routine screening matters most and tends to happen least. The options listed here vary in fee structure, which makes the cost column worth reading carefully before you go. For someone in a single-earner household, common in a town where overall workforce participation is moderate, the difference between a sliding-scale clinic and a full-fee visit can be a month's worth of a utility bill, and options listed here are designed with exactly that gap in mind.

Confidentiality & consent in Washington

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

Two things that actually depend on Washington 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 Washington, 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)

Washington 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.
