Yakima Valley Farm Workers Clinic in Yakima tests for gonorrhea, syphilis, chlamydia, HIV, herpes, and hepatitis on a sliding-scale fee open to everyone, with appointments required and same-visit treatment available for bacterial infections.
Leaving herpes or hepatitis untested means a separate appointment, a separate lab, and a separate bill. Gaps that quietly extend the window of an unmanaged infection. At Yakima Valley Farm Workers Clinic, testing for herpes, hepatitis A, B, and C sits alongside the standard bacterial and HIV panel, so nothing gets deferred to a follow-up you have to schedule yourself.
Yakima Valley Farm Workers Clinic prescribes and manages both PrEP and PEP directly, which means ongoing monitoring, lab work, and prescription renewals happen through the same clinical relationship rather than being handed off after an initial consultation.
Without language-matched care, a diagnosis can land without the context needed to act on it. A misunderstood treatment window or a prevention conversation that never fully lands. Yakima Valley Farm Workers Clinic delivers care in Spanish and provides interpretation across other languages, keeping clinical conversations complete from the first question to the last instruction.

STD stats & rates
How reported STI rates in Yakima County, the county that includes Union Gap, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~32% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#2 of 39 Washington counties for chlamydia, among the very highest in the state
| Infection | Yakima County | Washington | United States |
|---|---|---|---|
| Chlamydia | 743.1 1,907 cases ▲ 110% | 354.4 | 492.2 |
| Gonorrhea | 141.1 362 cases ▲ 9% | 129.6 | 179.5 |
| Syphilis (P&S) | 51.4 132 cases ▲ 141% | 21.3 | 15.8 |
| Syphilis (early) | 32.3 83 cases ▲ 158% | 12.5 | 16 |
| Syphilis (late/unknown) | 54.6 140 cases ▲ 138% | 22.9 | 29.5 |

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 Yakima County, chlamydia has risen from 638.8 to 743.1 per 100,000 (16%), gonorrhea has fallen from 231.8 to 141.1 per 100,000 (39%), and P&S syphilis has risen from 8.2 to 51.4 per 100,000 (527%).

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 Yakima County.
Local HIV snapshot
Yakima County HIV care continuum (2023)
Yakima County recorded 8.3 new HIV diagnoses per 100,000 (2023), against 6.3 statewide and 13.7 nationally. Among Yakima County residents living with HIV, 87.8% are in care · 79.4% 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 Yakima County tests for syphilis.

Local context
Union Gap sits in the shadow of the Cascades, where winters grip hard and families tend to stay put for years. That stability, the kind that comes with owning a home and raising kids in the same neighborhood, makes it easy to let routine health care slip. STI screening doesn't demand drama or crisis; it fits into the ordinary checkups that keep people well, especially for the young adults moving through their twenties and thirties who live and work here. Testing in and around Union Gap is listed on this page, accessible without fanfare or long waits.
For households where multiple generations share space and privacy matters, confidentiality is straightforward: results remain yours alone, with no surprises shared with family, employers, or anyone else. The clinics serving the area understand that people here value directness and affordability. Whether you're new to the area or rooted in a family business on Main Street, routine screening is a practical step that fits into life as it actually happens. Between work shifts, around school pickups, without becoming a story anyone else needs to know.

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.
