Nash County Health Department in Nashville tests for gonorrhea, chlamydia, syphilis, HIV, herpes, and hepatitis A, B, and C on a sliding scale with Medicaid, Medicare, and private insurance accepted, and all services are provided at no fee. Appointments are required; bacterial STIs are treated the same visit.
For anyone without a regular provider, or paying entirely out of pocket, Nash County Health Department's standing policy covers testing, treatment, vaccines, and counseling without a remaining balance. No service is carved out, and no income tier changes that.
Without Spanish-language clinical care on-site, an appointment often becomes two: one to learn what's needed, another to actually get it, or it ends with an untreated gap. Nash County Health Department delivers STI counseling, testing, and treatment directly in Spanish, collapsing that gap into a single visit.
Someone without a primary care provider, and paying cash, often has to piece together herpes and hepatitis testing separately, at separate costs. Nash County Health Department runs all of it in one appointment, covering hepatitis A, B, and C alongside herpes, syphilis, gonorrhea, chlamydia, and HIV under the same no-fee structure.

Rural Health Group in Hollister runs on sliding-scale fees with Medicaid, Medicare, and private insurance accepted, and tests for gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis A, B, and C, and TB. Appointments required, with care delivered in Spanish.
Spanish-language care at Rural Health Group is a staffed clinical capacity: meaning test results, treatment plans, and follow-up instructions move through the same provider relationship, in Spanish, without a handoff. That continuity reaches from the initial intake through any STI treatment prescribed the same day.
Rural Health Group tests for herpes and all three hepatitis strains alongside the standard bacterial and HIV panel, which means a single appointment surfaces infections that a narrower panel would leave undetected, and that would otherwise require a separate visit to catch.

STD stats & rates
How reported STI rates in Nash County, the county that includes Castalia, 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.
#17 of 100 North Carolina counties for chlamydia, a higher rate than 83% of the state
| Infection | Nash County | North Carolina | United States |
|---|---|---|---|
| Chlamydia | 854.5 825 cases ▲ 41% | 607.9 | 492.2 |
| Gonorrhea | 437.1 422 cases ▲ 80% | 243.2 | 179.5 |
| Syphilis (P&S) | 49.7 48 cases ▲ 150% | 19.9 | 15.8 |
| Syphilis (early) | 37.3 36 cases ▲ 136% | 15.8 | 16 |
| Syphilis (late/unknown) | 40.4 39 cases ▲ 68% | 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 Nash County, chlamydia has risen from 739.2 to 854.5 per 100,000 (16%), gonorrhea has fallen from 498.1 to 437.1 per 100,000 (12%), and P&S syphilis has risen from 11.6 to 49.7 per 100,000 (328%).

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 Nash County.
Local HIV snapshot
Nash County HIV care continuum (2023)
Nash County recorded 24.4 new HIV diagnoses per 100,000 (2023), against 15.1 statewide and 13.7 nationally. Among Nash County residents living with HIV, 80.7% are in care · 69.3% 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 Nash County tests for syphilis.

Local resources & officials
Data & references
Local context
Castalia's STI picture sits within Nash County's broader rural health landscape, where rates reflect the same gaps in routine care that affect small communities across the region, and where a high unemployment rate and nearly half the adult population outside the labor force mean that cost and scheduling loom large for younger adults trying to fit a screening visit into a constrained week. For people in their late teens and twenties, who face the steepest likelihood of an undetected infection, those practical barriers are the real obstacle: not stigma, not awareness, but simply whether a clinic is reachable and affordable on a Tuesday when the car isn't available or the co-pay isn't there. The community's character shapes that calculus in specific ways.
With roughly four in five households owning their homes and an average household running close to three people, Castalia skews toward rooted, family-oriented life, yet a modest share of high-earning households means that even a low-cost visit requires planning. Before making that drive from Castalia, checking which listed sites offer sliding-scale fees will do more to clear the path than any other single step.
Getting there
At 3.8/20 on the EPA walkability index, day-to-day errands in Castalia 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.
