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

Johnston County Public Health Department in Smithfield extends its full STI panel (HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, and TB) at no fee across the board, with Medicaid and insurance also accepted; bacterial STIs are treated the same visit, and appointments are required.
The no-fee structure at Johnston County Public Health Department isn't limited to HIV testing or a single program line: it covers the entire menu, from herpes and TB tests to hepatitis C treatment and the mpox vaccine. That means the cost of walking in is the same regardless of which services a visit requires: zero.
Spanish is supported directly at Johnston County Public Health Department, which means medical conversations (consent, diagnosis, treatment instructions) happen in Spanish without relay. For patients whose primary language is Spanish, clinical accuracy and comprehension aren't separated by a communication gap.
Johnston County Public Health Department tests for hepatitis C and carries treatment through to completion on-site. A confirmed hepatitis C diagnosis doesn't stall at the antibody result, the department manages the treatment course directly, keeping care continuous without sending patients elsewhere to find a prescriber.

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.

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.

STD stats & rates
How reported STI rates in Johnston County, the county that includes Smithfield, compare with North Carolina and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~21% 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 |
| Syphilis (P&S) | 12 29 cases ▼ 40% | 19.9 | 15.8 |
| Syphilis (early) | 5.4 13 cases ▼ 66% | 15.8 | 16 |
| Syphilis (late/unknown) | 18.2 44 cases ▼ 24% | 24 | 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 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
Smithfield tilts almost evenly between owners and renters (just over half own, and nearly half rent) which tells you something real about who's navigating day-to-day finances here. With typical rents well below state averages, many households are managing on modest, carefully stretched budgets, and that includes younger adults in their late teens and twenties, the years when STI rates nationally run hottest. When a test feels like one more errand competing with a work shift, a childcare pickup, or a bus connection along West Market Street, it doesn't happen. The clinics listed on this page exist precisely to change that arithmetic.
That near-even tenure split also reflects a community with real churn (renters moving in and out, households forming and re-forming) alongside a large average household size that suggests people living close together and sharing economic pressures. With labor-force participation notably below typical benchmarks and unemployment above it, scheduling flexibility is uneven: some residents have it, many don't. Shorter clinic windows and walk-in options on North Brightleaf Boulevard or near Town Commons Park aren't conveniences so much as necessities. Johnston County's STI picture makes routine screening genuinely worth building into a regular rhythm.
With the local options ranging widely in hours and fees, most people in Smithfield can find something that fits between shifts or across a lunch break. Not as an ideal, but as a regular Tuesday.
Getting there
At 8/20 on the EPA walkability index, day-to-day errands in Smithfield 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 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.
