Moses Lake Community Health Center in Quincy runs on scheduled appointments, so a single booked visit covers gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis A, B, and C testing, same-visit bacterial treatment, HPV and hepatitis vaccines, and sliding-scale fees. With services available in Spanish.
The testing panel at Moses Lake Community Health Center extends to herpes simplex and all three hepatitis strains (A, B, and C) each requiring its own assay and clinical interpretation. That breadth means a single appointment generates a fuller picture of viral exposure without scheduling separate visits to separate providers.
Substance-use treatment is a named service at Moses Lake Community Health Center, documented alongside STI care in the same clinical record. When both conditions are managed by the same provider team, treatment decisions for one can account for the other: dosing, adherence, and follow-up are coordinated rather than siloed.
Moses Lake Community Health Center delivers care directly in Spanish, which means test results, treatment instructions, and follow-up planning are communicated in the same language throughout. Preserving accuracy in the details that most affect whether a treatment plan is actually followed.

Planned Parenthood of Greater Washington and North Idaho in Moses Lake runs appointments for gonorrhea, chlamydia, syphilis, herpes, and rapid HIV testing, with same-visit treatment for bacterial infections, sliding-scale fees, and Spanish-language care available alongside other interpretation services.
Spanish is a working clinical language at this Moses Lake location, not routed through an outside service, and interpretation is available for additional languages. That operational capacity means a patient's history, test results, and treatment instructions are communicated with the same clinical precision regardless of which language anchors the conversation.
As a Title X-funded site, Planned Parenthood of Greater Washington and North Idaho is legally required to provide confidential family planning services to minors. Meaning those services are protected from parental disclosure by federal program rules, not clinic policy. That structure is built into the funding, not offered at discretion.
Prevention prescribing at many clinics stops at PrEP, DoxyPEP, the post-exposure doxycycline regimen for bacterial STI prevention, remains outside what most offer. At this Moses Lake clinic, PrEP, PEP, and DoxyPEP are all prescribable, covering HIV pre-exposure, post-exposure, and bacterial prevention within a single appointment.

Confluence Health in Moses Lake is a full-service health system offering gonorrhea, chlamydia, syphilis, and HIV testing on a sliding-scale fee, with same-visit treatment for bacterial infections; appointments are required, and HPV and hepatitis vaccines are available on-site.
Confluence Health prescribes and manages PrEP with the regular lab monitoring the regimen requires (kidney function, HIV status, and STI screening built into follow-up visits) rather than outsourcing that coordination elsewhere. PEP is also available when prevention needs fall outside the daily-pill timeline.
Confluence Health's standing capability covers hepatitis C from antibody test through antiviral treatment on-site, the clinic that makes the diagnosis also carries the prescription. For someone without a primary care provider in Moses Lake, that continuity means the medication isn't contingent on a separate specialist relationship.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Confluence Health tests for hepatitis B and hepatitis C in the same appointment. Useful for anyone whose exposure history calls for a wider look or who lacks a primary doctor ordering bloodwork elsewhere. TB testing rounds out the panel further.

STD stats & rates
How reported STI rates in Grant County, the county that includes Ephrata, compare with Washington and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#7 of 39 Washington counties for chlamydia, a higher rate than 82% of the state
| Infection | Grant County | Washington | United States |
|---|---|---|---|
| Chlamydia | 456.8 469 cases ▲ 29% | 354.4 | 492.2 |
| Gonorrhea | 101.3 104 cases ▼ 22% | 129.6 | 179.5 |
| Syphilis (P&S) | 21.4 22 cases ≈ the state average | 21.3 | 15.8 |
| Syphilis (early) | 14.6 15 cases ▲ 17% | 12.5 | 16 |
| Syphilis (late/unknown) | 22.4 23 cases ▼ 2% | 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 Grant County, chlamydia has risen from 305.7 to 456.8 per 100,000 (49%), gonorrhea has fallen from 115 to 101.3 per 100,000 (12%), and P&S syphilis has risen from 8.1 to 21.4 per 100,000 (164%).

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 Grant County.
Local HIV snapshot
Grant County HIV care continuum (2022)
Grant County recorded 7.4 new HIV diagnoses per 100,000 (2022), against 6.3 statewide and 13.7 nationally. Among Grant County residents living with HIV, 75.7% are in care · 65.7% 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 Grant County tests for syphilis.

Data & references
Local context
Splash Zone and the Ephrata Sports Complex draw families and younger adults from across the Basin Street corridor on summer evenings, and that same stretch of WA 28 connects most of Ephrata's daily errands, including the options listed here for STI screening. That everyday geography matters, because a meaningful share of residents are in their late teens and twenties, the years when chlamydia, gonorrhea, and other infections circulate most actively and when testing is most likely to be deferred simply because the day is already full. Ephrata skews toward homeowners, and households here run large, averaging well over three people, which shapes how time and money move through a family.
With nearly a quarter of households clearing six figures but a notable unemployment rate keeping budgets tighter for others, the $696 typical rent reflects a community where cost pressure is real for renters piecing together a monthly budget. Affordable or sliding-scale options listed on this page make a concrete difference when a co-pay competes with groceries. That unemployment figure also means schedules are uneven across town: some residents have flexible midweek hours while others juggle multiple jobs or irregular shifts.
Getting there
At 3.34/20 on the EPA walkability index, day-to-day errands in Ephrata generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
