STD stats & rates
How reported STI rates in Barnwell County, the county that includes Williston, compare with South Carolina and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#14 of 46 South Carolina counties for chlamydia, a higher rate than 70% of the state
| Infection | Barnwell County | South Carolina | United States |
|---|---|---|---|
| Chlamydia | 836.3 171 cases ▲ 37% | 612.1 | 492.2 |
| Gonorrhea | 288.6 59 cases ▲ 30% | 222.4 | 179.5 |
| Syphilis (P&S) | 19.6 4 cases ▲ 13% | 17.3 | 15.8 |
| Syphilis (early) | 4.9 1 cases ▼ 74% | 18.8 | 16 |
| Syphilis (late/unknown) | 24.5 5 cases ▲ 109% | 11.7 | 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 Barnwell County, chlamydia has risen from 777.1 to 836.3 per 100,000 (8%), gonorrhea has fallen from 495.4 to 288.6 per 100,000 (42%), and P&S syphilis has risen from 14.6 to 19.6 per 100,000 (34%).

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 Barnwell County.
Local HIV snapshot
Federal priority area: South Carolina is one of the U.S. jurisdictions prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Barnwell County HIV care continuum (2023)
Among Barnwell County residents living with HIV, 82.4% are in care · 72.2% 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 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 Barnwell County tests for syphilis.

Local resources & officials
Data & references
Local context
Main Street and Church Street divide Williston into the rhythms most residents actually live by, and for the younger adults sharing households along those corridors, the math of a $600 monthly rent and a household size that regularly stretches across three or four people means tight budgets and shared calendars leave little room for appointments that aren't strictly necessary. That calculation quietly shapes who follows through on routine screening and who keeps meaning to. The town's workforce picture adds another layer: with just over half of adults actively employed and unemployment running noticeably higher than state norms, the people most likely to be in their late teens and twenties (forming new relationships, changing living situations, navigating the stretch between renter and eventual homeowner in a market where that transition is genuinely within reach) are also the ones juggling irregular hours and financial pressure.
Both realities point toward the same need: testing options that don't require burning a day or a paycheck to access. Knowing that before you search, rather than after you've committed to a time slot, is what turns Williston Town Park's quiet afternoon into a realistic window for planning ahead.

Two things that actually depend on South Carolina 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 South Carolina, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
South Carolina 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.
