STD stats & rates
How reported STI rates in McLean County, the county that includes Colfax, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~28% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#14 of 102 Illinois counties for chlamydia, a higher rate than 86% of the state
| Infection | McLean County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 535.1 912 cases ▼ 4% | 557.7 | 492.2 |
| Gonorrhea | 211.8 361 cases ▲ 5% | 202.3 | 179.5 |
| Syphilis (P&S) | 2.9 5 cases ▼ 75% | 11.6 | 15.8 |
| Syphilis (early) | 2.9 5 cases ▼ 73% | 10.9 | 16 |

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 McLean County, chlamydia has fallen from 596.1 to 535.1 per 100,000 (10%), gonorrhea has risen from 170.2 to 211.8 per 100,000 (24%), and P&S syphilis has fallen from 8.8 to 2.9 per 100,000 (67%).

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 McLean County.
Local HIV snapshot
McLean County HIV care continuum (2023)
McLean County recorded 9.6 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among McLean County residents living with HIV, 86.6% are in care · 77.3% 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 McLean County tests for syphilis.

Data & references
Local context
Colfax households tend toward stability: people who buy here, build lives here, and stay. That rootedness shapes how the community thinks about health. Families often span generations under one roof, and work schedules run tight; routine screening for STIs fits best when it's straightforward and fits into real life, not around it. Testing available in and around Colfax listed on this page meets that need without requiring a long search or a story to explain.
Young adults in their late teens through thirties make up a significant presence in town, and they know that confidential screening is part of staying healthy. The clinics and providers serving Colfax understand that discretion and directness matter equally: appointments happen without fanfare, results remain private, and the focus stays on what the person actually needs. That clarity removes a barrier many people face when they first think about getting tested. Octavia Park anchors the community's gathering life, but the real anchor for health is knowing where to go and what to expect.
Testing in Colfax is accessible to residents who work full days, manage households, and want the facts without judgment. The providers listed here work with that reality, not against it.

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.
