STD stats & rates
How reported STI rates in Randolph County, the county that includes Houston, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~24% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#38 of 102 Illinois counties for chlamydia, a higher rate than 63% of the state
| Infection | Randolph County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 298.5 89 cases ▼ 46% | 557.7 | 492.2 |
| Gonorrhea | 107.3 32 cases ▼ 47% | 202.3 | 179.5 |
| Syphilis (P&S) | 16.8 5 cases ▲ 45% | 11.6 | 15.8 |
| Syphilis (early) | 10.1 3 cases ▼ 7% | 10.9 | 16 |
| Syphilis (late/unknown) | 43.6 13 cases ▲ 68% | 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 Randolph County, chlamydia has risen from 291.7 to 298.5 per 100,000 (2%), gonorrhea has fallen from 149.2 to 107.3 per 100,000 (28%), and P&S syphilis has risen from 6.6 to 16.8 per 100,000 (155%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Randolph County.
Local HIV snapshot
Randolph County HIV care continuum (2021)
Randolph County recorded 0 new HIV diagnoses per 100,000 (2021), against 14.7 statewide and 13.7 nationally. Among Randolph County residents living with HIV, 71% are in care · 61.3% 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 Randolph County tests for syphilis.

Data & references
Local context
Along IL 154's West Broadway Street, where the storefronts thin out quickly and a monthly rent of $723 can consume most of a paycheck, missing a clinic appointment to cover that payment is less a choice than a calculation. Houston, Illinois is a predominantly owner-occupied town, but the renters here, about three in ten households, often carry the tightest margins, and even among homeowners the combination of a high jobless share and smaller household sizes means discretionary spending on health visits can feel like a genuine trade-off. That tension matters most for younger adults in their late teens and twenties, who account for a meaningful slice of Houston's population and represent the years when STI transmission peaks.
With the testing options listed here, the range of fees and hours is real, and some of those options are lower-cost or free, which changes the calculation considerably. A workforce participation rate below 60 percent also means some residents are working non-standard hours or juggling caregiving near Baldwin Village Park's quieter residential side of town, making evening or weekend availability more than a convenience. Knowing which of the clinics opens early or charges on a sliding scale is the practical starting point.
Getting there
At 7.06/20 on the EPA walkability index, day-to-day errands in Houston generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
