North Star Health in Charlestown tests for gonorrhea, syphilis, chlamydia, herpes, hepatitis A, B, and C, and HIV on a sliding-scale fee open to everyone, with walk-ins welcome and same-visit treatment available for bacterial STIs.
A hepatitis C diagnosis without a treatment path attached to it means weeks of follow-up calls, specialist wait lists, and a condition that keeps advancing in the meantime. North Star Health closes that gap, treatment is managed on-site in Charlestown, so the clinical relationship that caught the infection is the same one that treats it.
Most testing sites cover gonorrhea, chlamydia, syphilis, and HIV and leave herpes and hepatitis off the panel entirely. North Star Health tests for herpes, hepatitis A, B, and C, and tuberculosis alongside the core four. Infections that carry real consequences when they go undetected simply because no one offered the test.

STD stats & rates
How reported STI rates in Sullivan County, the county that includes Charlestown, compare with New Hampshire 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.
#7 of 10 New Hampshire counties for chlamydia, a higher rate than 30% of the state
| Infection | Sullivan County | New Hampshire | United States |
|---|---|---|---|
| Chlamydia | 141 62 cases ▼ 28% | 196.6 | 492.2 |
| Gonorrhea | 13.6 6 cases ▼ 68% | 41.9 | 179.5 |
| Syphilis (P&S) | 2.3 1 cases ▼ 41% | 3.9 | 15.8 |
| Syphilis (early) | 4.5 2 cases ▲ 137% | 1.9 | 16 |

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 Sullivan County, chlamydia has risen from 127.7 to 141 per 100,000 (10%), gonorrhea has risen from 7 to 13.6 per 100,000 (94%), and P&S syphilis has held roughly steady from 2.3 to 2.3 per 100,000.

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 Sullivan County.
Local HIV snapshot
Sullivan County HIV care continuum (2023)
Sullivan County recorded 0 new HIV diagnoses per 100,000 (2023), against 2.8 statewide and 13.7 nationally. Among Sullivan County residents living with HIV, 93.8% are in care · 90.6% 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 Sullivan County tests for syphilis.

Data & references
Local context
The stretch of North Main Street that becomes NH 12 heading south toward Claremont is the practical axis of daily life here, and a clinic run from Charlestown's center is a real road trip, not a quick errand, in a town where most people depend entirely on a car. That driving reality lands differently depending on your week. With barely more than half of working-age residents in the labor force and unemployment running noticeably above state norms, schedules here aren't always nine-to-five, but they can be irregular, unpredictable, and exhausting in different ways. Rent hovering just under a thousand dollars a month also means that for the roughly one-in-four households who rent near the Charlestown Main Street Historic District or further out toward Breakneck Hill, a clinic copay competes with fixed monthly costs.
Those pressures fall hardest on younger adults (people still in their late teens and twenties, early in relationships and careers) precisely the years when routine STI screening matters most and tends to get postponed longest. Charlestown is a predominantly owner-occupied, married-household community, which can make sexual health feel like a private matter nobody discusses openly. The testing options listed here include low-cost and sliding-scale clinics reachable off Claremont Road, so the choice of when, not whether, to get tested stays yours.
Getting there
At 6.34/20 on the EPA walkability index, day-to-day errands in Charlestown 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 New Hampshire 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 New Hampshire, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
New Hampshire 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.
