STD stats & rates
How reported STI rates in Knox County, the county that includes Centerburg, compare with Ohio 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.
#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 |
| Syphilis (P&S) | 9.5 6 cases ▼ 42% | 16.3 | 15.8 |

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%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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
Centerburg Square anchors a town that feels deliberately unhurried, the kind of place where the Geographical Center of Ohio draws the occasional curious traveler down Columbus Road and locals tend to stay put. That stability shows in the ownership split: just over half of households own their homes, while the rest rent at rates that sit well below state averages, a detail that matters because cost pressure shapes whether a health appointment gets scheduled or quietly shelved. What complicates things is the getting there.
Young adults in their late teens and twenties represent a meaningful slice of Centerburg's population, and for that group, relationship formation, inconsistent coverage, and the logistics of rural travel all converge in ways that make low-barrier options worth knowing about in advance, not after the fact. For the portion of households earning under the hundred-thousand-dollar threshold, which describes the large majority here, the sliding-scale and no-cost options listed on this page carry more weight than a line item on a benefits summary. At $619 a month in rent, a surprise out-of-pocket lab fee isn't abstract; it's a decision point.
Getting there
At 3.98/20 on the EPA walkability index, day-to-day errands in Centerburg 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 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.
