STD stats & rates
How reported STI rates in Adams County, the county that includes Mendon, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~16% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#23 of 102 Illinois counties for chlamydia, a higher rate than 77% of the state
| Infection | Adams County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 401.9 259 cases ▼ 28% | 557.7 | 492.2 |
| Gonorrhea | 114.8 74 cases ▼ 43% | 202.3 | 179.5 |
| Syphilis (P&S) | 1.6 1 cases ▼ 86% | 11.6 | 15.8 |
| Syphilis (early) | 1.6 1 cases ▼ 85% | 10.9 | 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 Adams County, chlamydia has risen from 366.6 to 401.9 per 100,000 (10%), gonorrhea has fallen from 267.7 to 114.8 per 100,000 (57%), and P&S syphilis has fallen from 3 to 1.6 per 100,000 (47%).

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 Adams County.
Local HIV snapshot
Adams County HIV care continuum (2023)
Among Adams County residents living with HIV, 88.1% are in care · 83.3% 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 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 Adams County tests for syphilis.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
Two things that actually depend on Illinois 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 Illinois, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Illinois 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.
