STD stats & rates
How reported STI rates in Jersey County, the county that includes Grafton, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~19% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#80 of 102 Illinois counties for chlamydia, a higher rate than 22% of the state
| Infection | Jersey County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 184.9 39 cases ▼ 67% | 557.7 | 492.2 |
| Gonorrhea | 37.9 8 cases ▼ 81% | 202.3 | 179.5 |
| Syphilis (P&S) | 4.7 1 cases ▼ 59% | 11.6 | 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 Jersey County, chlamydia has risen from 162.7 to 184.9 per 100,000 (14%), gonorrhea has fallen from 83.7 to 37.9 per 100,000 (55%), and P&S syphilis has held roughly steady from 4.7 to 4.7 per 100,000.
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 Jersey County.
Local HIV snapshot
Jersey County HIV care continuum (2023)
Jersey County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Jersey County residents living with HIV, 87.5% are in care · 87.5% 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 Jersey County tests for syphilis.

Data & references
Local context
Illinois Route 100 threads through Grafton as East Main, River Road, and West Main. The same asphalt carrying most daily life in a town where the majority of residents own their homes outright and a notably smaller share rents. That ownership-heavy character shapes the community in ways worth naming: long-term residents, stable households, and a younger adult population that is comparatively small but no less present. People in their late teens and twenties here are often navigating new relationships while living in a place where social circles are tight and healthcare logistics aren't taken for granted. The labor-force picture adds texture.
With participation well below typical urban levels, many residents are outside the standard nine-to-five rhythm: whether retired, caregiving, or working irregular hours. For those who are employed and juggling Grafton's pace of life, carving out time for routine screening can sit low on the week's agenda without a clear, easy path forward. The roughly one-in-five households earning above six figures coexists with real economic range across town, meaning cost-conscious options among the clinics listed on this page genuinely matter to different residents for different reasons. Knowing which clinics open early, run late, or offer sliding-scale fees before you make that drive is the detail that actually determines whether screening happens.
Getting there

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.
