STD stats & rates
How reported STI rates in Johnston County, the county that includes Four Oaks, compare with North Carolina and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#52 of 100 North Carolina counties for chlamydia, a higher rate than 48% of the state
| Infection | Johnston County | North Carolina | United States |
|---|---|---|---|
| Chlamydia | 450.9 1,091 cases ▼ 26% | 607.9 | 492.2 |
| Gonorrhea | 172.8 418 cases ▼ 29% | 243.2 | 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 Johnston County, chlamydia has risen from 418.5 to 450.9 per 100,000 (8%), gonorrhea has risen from 158.8 to 172.8 per 100,000 (9%), and P&S syphilis has risen from 10.6 to 12 per 100,000 (13%).

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 Johnston County.
Local HIV snapshot
Johnston County HIV care continuum (2023)
Johnston County recorded 7.5 new HIV diagnoses per 100,000 (2023), against 15.1 statewide and 13.7 nationally. Among Johnston County residents living with HIV, 74.7% are in care · 65.8% 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 Johnston County tests for syphilis.

Data & references
Local context
US 301 through the middle of town (East Wellons Street on one side, West Wellons Street on the other) means the nearest clinic listed here is a straight shot out of Four Oaks, though still a real drive for anyone without flexible time. Nearly half of residents here rent, and at typical local rents that leave little room for discretionary spending, the cost and scheduling details on this page carry genuine weight. Johnston County's STI picture makes routine screening worth taking seriously, especially for young adults in their late teens and twenties: a group that forms a meaningful slice of Four Oaks' population and tends to move through relationships, jobs, and living situations in ways that raise exposure risk.
Knowing ahead of time which of options listed here takes walk-ins, which charges on a sliding scale, and which sits closest to South Brightleaf Boulevard can be the deciding factor when a weekday window opens unexpectedly. Four Oaks households run large and lean toward a mix of owned and rented homes, with plenty of married couples alongside single-person and multigenerational arrangements. Screening fits differently into each of those lives, but the logistics on this page apply to all of them.
Getting there
At 2.56/20 on the EPA walkability index, day-to-day errands in Four Oaks 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 North 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 North Carolina, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
North 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.
