STD stats & rates
How reported STI rates in Knox County, the county that includes Martinsburg, compare with Ohio and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#78 of 88 Ohio counties for chlamydia, a higher rate than 11% of the state
| Infection | Knox County | Ohio | United States |

| Chlamydia | 156.3 99 cases ▼ 66% | 461.7 | 492.2 |
| Gonorrhea | 26.8 17 cases ▼ 84% | 168 | 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 Knox County, chlamydia has fallen from 245.5 to 156.3 per 100,000 (36%), gonorrhea has fallen from 63.8 to 26.8 per 100,000 (58%), and P&S syphilis has risen from 1.6 to 9.5 per 100,000 (494%).

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 Knox County.
Local HIV snapshot
Knox County HIV care continuum (2023)
Knox County recorded 0 new HIV diagnoses per 100,000 (2023), against 8.8 statewide and 13.7 nationally. Among Knox County residents living with HIV, 91.9% are in care · 91.9% 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 Knox County tests for syphilis.

Data & references
Local context
SR 586 cuts through Martinsburg as both South Market Street and Zanesville Street, bisecting a town where households are notably large and nearly half of residents rent rather than own. That tenure split matters for testing access: renters at a $663 monthly rent tend to operate on tighter margins than homeowners, and when budgets are stretched, a clinic visit can fall off the list before groceries or utilities do. The unemployment rate here is meaningfully elevated, which means a sizable share of working-age adults are navigating stretches without employer coverage or a predictable paycheck. Exactly the conditions under which routine screening feels like a luxury rather than a given.
Young adults in their late teens and twenties make up a substantial portion of Martinsburg's population, and for that group, forming new relationships while managing real financial pressure is the daily reality. Low-cost, straightforward access to testing isn't an abstract amenity. It's what determines whether someone actually follows through. The options listed on this page span enough variety in hours and fee structures that a resident working irregular shifts along US 62, or piecing together part-time work, can likely find an appointment that doesn't force a choice between a lost shift and skipping the visit altogether.
Getting there

Two things that actually depend on Ohio 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 Ohio, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Ohio 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.
