Southern Illinois Healthcare Foundation in Centreville requires an appointment, so scheduling ahead unlocks a visit that covers HIV, syphilis, gonorrhea, chlamydia, hepatitis A, B, and C, and TB: with same-visit treatment for bacterial infections, sliding-scale fees, and care available in Spanish.
Spanish-language care at Southern Illinois Healthcare Foundation is staffed capacity, not a workaround: clinicians conduct assessments, prescribe treatment, and manage follow-up directly in Spanish. That means medication instructions, lab results, and ongoing HIV or hepatitis monitoring are communicated by the provider doing the work, not relayed through a secondary channel.
Many testing sites hand off a positive HIV result with nowhere structured to send someone for long-term care. Southern Illinois Healthcare Foundation holds Ryan White funding, which means it carries patients from initial HIV testing through ongoing medical treatment: prescribing, monitoring, and managing HIV/AIDS care as a sustained clinical relationship, not a one-time encounter.
Chasing a PrEP prescription across two separate providers means delays, duplicate visits, and stretches of unprotected time that add up. Southern Illinois Healthcare Foundation prescribes and manages PrEP on-site, and also provides PEP, so prevention medication is initiated and monitored by the same clinic handling your testing, without routing you elsewhere to begin.

STD stats & rates
How reported STI rates in St. Clair County, the county that includes Centreville, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~22% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#3 of 102 Illinois counties for chlamydia, among the very highest in the state
| Infection | St. Clair County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 815.5 2,047 cases ▲ 46% | 557.7 | 492.2 |
| Gonorrhea | 347.4 872 cases ▲ 72% | 202.3 | 179.5 |
| Syphilis (P&S) | 21.5 54 cases ▲ 85% | 11.6 | 15.8 |
| Syphilis (early) | 7.6 19 cases ▼ 30% | 10.9 | 16 |
| Syphilis (late/unknown) | 46.6 117 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 St. Clair County, chlamydia has fallen from 849.3 to 815.5 per 100,000 (4%), gonorrhea has fallen from 432.4 to 347.4 per 100,000 (20%), and P&S syphilis has risen from 21.4 to 21.5 per 100,000 (0%).

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 St. Clair County.
Local HIV snapshot
St. Clair County HIV care continuum (2023)
St. Clair County recorded 18.4 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among St. Clair County residents living with HIV, 78.8% are in care · 66.4% 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 St. Clair County tests for syphilis.

Data & references
Local context
A weekday errand to the Majestic Theater or a Saturday visit to Malcolm W. Martin Memorial Park bookends the week for many Centreville residents, and between those anchors, life moves fast. Young adults here, whether settling into first jobs, sharing rent with roommates, or managing household responsibilities across generations, often find that sexual health falls into that gap between intention and action. STI testing in and around Centreville sits within reach of daily routines, listed on this page, because the moment to get screened rarely announces itself in advance.
What draws people to testing is rarely the same twice over. A new relationship, a routine checkup, peace of mind after a lapse in protection. Each person's reason belongs to them alone. Centreville's affordability means many residents can absorb the cost of screening without strain, yet the real barrier is often just showing up.
Clinics and providers serving the area understand that confidentiality isn't theater; it's the baseline that lets someone walk in without rehearsing an explanation. The young adult presence in Centreville (renters, early-career workers, people navigating adulthood on modest wages) makes regular screening a straightforward public health fact, not a moral question. Testing happens quietly, results stay between patient and provider, and life continues. That simplicity, unremarkable as it sounds, is what makes the difference.
Getting there
Centreville scores 11.71/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
