A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

MainStreet Family Care in Smithfield accepts Medicaid, Medicare, and private insurance, with fees charged on a standard basis; sliding-scale is not listed, so costs follow coverage. The clinic tests for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B, and hepatitis C, treating bacterial infections the same visit and offering PrEP and PEP.
Without a regular provider, getting herpes serology or hepatitis B and C testing typically means coordinating between multiple offices. MainStreet Family Care runs the full expanded panel in a single visit: useful for anyone who needs documented results across all six infections for their own records, a new relationship, or an insurance requirement.
MainStreet Family Care prescribes and manages both PrEP, the daily oral medication that blocks HIV acquisition, and PEP, the short-course regimen taken after a potential exposure. Ongoing PrEP care includes the required HIV and kidney-function monitoring built into follow-up appointments, so the prescription and its clinical oversight stay with the same practice.

CommWell Health in Smithfield tests for HIV, syphilis, chlamydia, gonorrhea, hepatitis A, B, and C, and TB on a sliding scale open to everyone, with STI treatment available at the same visit: appointments required, and every service carries no fee for those who qualify.
An untreated STI often comes down to one thing: a charge that stopped someone at the door. CommWell Health eliminates that point of friction entirely: testing, treatment, vaccines, and HIV care are all provided at no fee, so the visit ends with care delivered, not a balance to figure out later.
CommWell Health in Smithfield delivers care in Spanish as a standing clinical capacity: meaning medication counseling, STI treatment decisions, and prevention education happen directly in Spanish with the care team, not routed through a workaround that loses nuance at exactly the moment precision matters.
CommWell Health's Ryan White Program funding means HIV care doesn't stop at a reactive result, it underwrites ongoing HIV/AIDS medical treatment and medication adherence counseling, sustaining the full continuum from initial testing through long-term management at the same Smithfield location.

STD stats & rates
How reported STI rates in Johnston County, the county that includes Selma, compare with North Carolina 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.
#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
Along North Pollock Street, where rental units fill the blocks nearest downtown, young adults are piecing together the gap years between a parent's insurance card and a first job that comes with benefits of its own. With two-thirds of residents renting rather than owning, and a typical monthly rent that leaves little room for anything that feels like an optional expense, an unplanned clinic visit can quietly lose to a tighter budget. That $820 a month doesn't stretch far when unemployment is running notably above typical rates and fewer than six in ten residents are in the labor force, meaning that cost and time both carry real weight when someone is deciding whether to follow through on getting screened. Getting around here adds another layer.
The testing options listed on this page include choices that vary by cost, hours, and distance. Worth comparing carefully when your schedule and your budget aren't both flexible at the same time. Households here tend to be larger, and the majority of adults aren't married, which means relationship structures are diverse and STI conversations are common life territory. Screening fits that reality straightforwardly, and Selma has enough options that finding one matching your situation is genuinely possible.
Getting there
At 6.54/20 on the EPA walkability index, day-to-day errands in Selma 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.
