STD stats & rates
How reported STI rates in Clinton County, the county that includes Trenton, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~25% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#81 of 102 Illinois counties for chlamydia, a higher rate than 21% of the state
| Infection | Clinton County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 182.1 67 cases ▼ 67% | 557.7 | 492.2 |
| Gonorrhea | 46.2 17 cases ▼ 77% | 202.3 | 179.5 |
| Syphilis (P&S) | — no data | 11.6 | 15.8 |
| Syphilis (early) | 2.7 1 cases ▼ 75% | 10.9 | 16 |
| Syphilis (late/unknown) | 5.4 2 cases ▼ 79% | 26 | 29.5 |

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 Clinton County, chlamydia has fallen from 252 to 182.1 per 100,000 (28%), gonorrhea has fallen from 56.9 to 46.2 per 100,000 (19%), and P&S syphilis has risen from 2.7 to 5.4 per 100,000 (100%).

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 Clinton County.
Local HIV snapshot
Clinton County HIV care continuum (2020)
Clinton County recorded 0 new HIV diagnoses per 100,000 (2020), against 14.7 statewide and 13.7 nationally. Among Clinton County residents living with HIV, 72.7% are in care · 63.6% 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 Clinton County tests for syphilis.

Data & references
Local context
Trenton Nature Park sits at the quiet edge of a town where most residents own their homes and nearly half of all adults are raising households together, a settled, family-oriented community that can still leave younger adults navigating relationship transitions without easy access to routine screening. That under-35 crowd, the group for which STI rates climb most sharply nationally, is a real presence here, and the low-key pace of Trenton life doesn't automatically translate into low-barrier care. With the nearest options listed on this page requiring a drive out of Clinton County, the practical question becomes less about awareness and more about carving time out of a working week. At a 62-percent labor-force participation rate, most Trenton adults are employed, and with unemployment remarkably low, many are working full schedules that leave little room for mid-day appointments in another town.
That's exactly where the range and variety of options listed here matters. A significant share of households carry real financial stability, but rental budgets around $724 a month leave less cushion for surprise costs, making the fee structures and sliding-scale availability shown in the clinic cards genuinely relevant. Evening or weekend hours among the listed providers mean a test doesn't require burning a weekday for someone clocking out near Nuthouse Park after a full shift.
Getting there
At 7.03/20 on the EPA walkability index, day-to-day errands in Trenton generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
