STD stats & rates
How reported STI rates in Madison County, the county that includes Collinsville, 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.
#21 of 102 Illinois counties for chlamydia, a higher rate than 79% of the state
| Infection | Madison County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 441.9 1,161 cases ▼ 21% | 557.7 | 492.2 |
| Gonorrhea | 160.2 421 cases ▼ 21% | 202.3 | 179.5 |
| Syphilis (P&S) | 17.5 46 cases ▲ 51% | 11.6 | 15.8 |
| Syphilis (early) | 5.7 15 cases ▼ 48% | 10.9 | 16 |
| Syphilis (late/unknown) | 17.1 45 cases ▼ 34% | 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 Madison County, chlamydia has fallen from 448 to 441.9 per 100,000 (1%), gonorrhea has fallen from 208.4 to 160.2 per 100,000 (23%), and P&S syphilis has risen from 7.5 to 17.5 per 100,000 (133%).

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 Madison County.
Local HIV snapshot
Madison County HIV care continuum (2023)
Madison County recorded 6.7 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Madison County residents living with HIV, 79.1% are in care · 64.5% 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 Madison County tests for syphilis.

Data & references
Local context
IL 157 stretches north through Collinsville past the World's Largest Catsup Bottle and out toward the county line, and for most people here, a clinic visit means getting in the car. That drive reality matters most for younger adults in their late teens and twenties, who face the highest likelihood of a new STI diagnosis and also tend to juggle the least predictable schedules. With unemployment running notably higher than state averages and a substantial share of the workforce in hourly or shift-dependent jobs, carving out a midday appointment can feel genuinely costly in lost wages, not just lost time. The housing picture adds texture too.
Nearly two-thirds of Collinsville households own their homes, which suggests a settled, rooted population, but the renters who remain face monthly costs that leave little cushion, and a household averaging nearly three people means that privacy, transportation, and scheduling often have to be negotiated around others. Testing options appear on this page, which means the practical question isn't whether Collinsville has access. It's which clinic fits a real commute down Vandalia Street or North Bluff Road.
Getting there
At 8.05/20 on the EPA walkability index, day-to-day errands in Collinsville 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.
