Plenty of STI panels stop at gonorrhea, chlamydia, syphilis, and HIV. Leaving herpes and hepatitis unexamined unless a patient specifically pushes for them. MainStreet Family Care in Goldsboro runs herpes, hepatitis B, and hepatitis C as part of its standard testing menu, closing that gap without requiring a separate visit.

Fees & payment
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 Princeton, compare with North Carolina and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~25% 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
Princeton Park sits at the quieter end of town, the kind of place where the pace feels unhurried, but the logistics of getting screened here are a different matter. Johnston County's STI rates give particular reason for younger adults still building their social lives to treat routine screening as a practical habit rather than an afterthought. The rental-heavy split here (just over half of households are renters, most paying rents that leave narrow margins) shapes what "easy access" actually looks like. Pair that with an unemployment rate that keeps a meaningful share of residents outside the structured rhythms of a traditional workday, and the case for clinics offering flexible hours or sliding-scale fees becomes concrete rather than abstract.
Larger households here also mean that one person's health decisions ripple outward through the people they live with. For the roughly one in ten households earning over a hundred thousand dollars, cost is rarely what stands between intention and a scheduled appointment. But for renters on a $734-a-month budget, with no employer insurance and a drive ahead of them, the sliding-scale and low-cost options flagged in the clinic cards on this page are the detail worth reading first.
Getting there
At 5.24/20 on the EPA walkability index, day-to-day errands in Princeton 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.
