STD stats & rates
How reported STI rates in Iowa County, the county that includes Williamsburg, compare with Iowa and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~33% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#65 of 99 Iowa counties for chlamydia, a higher rate than 34% of the state
| Infection | Iowa County | Iowa | United States |
|---|---|---|---|
| Chlamydia | 195.3 32 cases ▼ 54% | 426.8 | 492.2 |
| Gonorrhea | 24.4 4 cases ▼ 79% | 116.8 | 179.5 |
| Syphilis (P&S) | 6.1 1 cases ▼ 41% | 10.3 | 15.8 |
| Syphilis (early) | 12.2 2 cases ▲ 33% | 9.2 | 16 |
| Syphilis (late/unknown) | — no data | 9.9 | 29.5 |
Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Iowa County, chlamydia has fallen from 276.1 to 195.3 per 100,000 (29%), gonorrhea has fallen from 42 to 24.4 per 100,000 (42%), and P&S syphilis has held roughly steady from 6.1 to 6.1 per 100,000.
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Iowa County.
Local HIV snapshot
Iowa County HIV care continuum (2023)
Iowa County recorded 0 new HIV diagnoses per 100,000 (2023), against 5.1 statewide and 13.7 nationally. Among Iowa County residents living with HIV, 100% are in care · 100% 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 Iowa County tests for syphilis.

Data & references
Local context
South Highland Street runs through a Williamsburg where most households are owned, not rented, and most adults are married. A stability that can make it easy to assume the whole town has settled into long-term routines. But a substantial share of residents are young adults still in the early years of relationships and careers, and for them, the gap between knowing they should get tested and actually doing it tends to come down to logistics, not intention. The town's low rents and relatively high homeownership rate suggest a community where people plant roots, but "settled" doesn't mean insulated. With nearly seven in ten residents in the workforce and unemployment a real presence, schedules are full and unpredictable.
Those realities hit younger adults hardest, people juggling new jobs or hourly shifts rarely have the flexibility to treat a health appointment as something they can simply slot in. The options listed on this page offer a range of hours and cost structures that can work around those constraints. That means getting to any of the clinics listed here requires a deliberate trip. Knowing that in advance, and planning accordingly, is what actually gets it done.
Getting there
At 6/20 on the EPA walkability index, day-to-day errands in Williamsburg generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
Two things that actually depend on Iowa 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 Iowa, a minor of any age can consent to confidential STI testing and treatment on their own; a parent may be notified only in the case of a positive HIV test result.
Iowa 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.
