STD stats & rates
How reported STI rates in King County, the county that includes Lake Marcel-Stillwater, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~12% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#18 of 39 Washington counties for chlamydia, a higher rate than 54% of the state
| Infection | King County | Washington | United States |
|---|---|---|---|
| Chlamydia | 324 7,360 cases ▼ 9% | 354.4 | 492.2 |
| Gonorrhea | 198.5 4,509 cases ▲ 53% | 129.6 | 179.5 |

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.
Between 2020 and 2023 in King County, chlamydia has fallen from 373.4 to 324 per 100,000 (13%), gonorrhea has risen from 192 to 198.5 per 100,000 (3%), and P&S syphilis has risen from 14.8 to 25.4 per 100,000 (72%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in King County.
Local HIV snapshot
Federal priority area: King County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
King County HIV care continuum (2023)
King County recorded 9 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among King County residents living with HIV, 88% know their status · 87% are in care · 79.1% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
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 King County tests for syphilis.

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).
In Washington, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
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.
