STD stats & rates
How reported STI rates in St. Clair County, the county that includes Smithton, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~17% 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
Smithton took its name from the smith's forge that once anchored the town's commercial core, a reminder that this place was built on steady work and staying put. That same ethos runs through the community today: families and long-term residents who tend to their homes and their health with equal care. For the young adults who live here (those in their late teens through thirties who are establishing careers, starting families, or simply moving through active years) routine STI testing fits naturally into responsible health habits, no different from an annual physical or dental checkup. Testing in and around Smithton reflects the town's practical character: clinics and providers listed on this page offer straightforward, confidential screening without fanfare or judgment. Results remain private; what happens in a testing room stays there.
The working rhythms of Smithton families mean that flexible scheduling and quick turnaround matter, and the providers serving the area understand that. Whether you're new to the community or have roots here spanning generations, the path to testing is direct. Confidentiality is built into how these services work, not as an afterthought, but as the baseline. The same discretion that allows neighbors to respect each other's business extends to health decisions, and testing sites in town honor that boundary as a matter of course.

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.
