Community Health Partnerships of Illinois in Champaign pairs rapid and conventional HIV testing with same-visit treatment for bacterial STIs (gonorrhea, chlamydia, and syphilis) on a sliding-scale fee accepted alongside Medicaid, Medicare, and private insurance, by appointment, with care available in Spanish.
Plenty of clinics in this region handle Spanish speakers through patchwork arrangements that keep the clinical encounter at arm's length. At Community Health Partnerships of Spanish is a language of care (the actual appointment, the history, the results conversation) not a logistical accommodation bolted onto an English-language visit.
For anyone without a regular primary care provider, or managing costs out of pocket, getting hepatitis B, hepatitis C, and TB screening at the same appointment as gonorrhea, chlamydia, syphilis, and HIV testing means one visit covers what would otherwise require multiple referrals. Community Health Partnerships of Illinois runs that broader panel in-house, on its sliding-scale fee structure.

Champaign-Urbana Public Health District tests for HIV, syphilis, gonorrhea, chlamydia, and hepatitis C, all at no fee, with bacterial STIs treated the same visit and PrEP available on-site; an appointment is required.
The no-fee structure here isn't a waiver applied at checkout, it's baked into how the clinic is funded and staffed. HIV counseling, hepatitis C testing, STI treatment, PrEP management, and mpox vaccination are all operated through public health funding streams that eliminate billing at the point of care entirely.
Without Ryan White-backed care in place, a positive HIV result often means a second appointment, a second provider, and a gap where treatment should be. Champaign-Urbana Public Health District closes that gap, Ryan White funding supports ongoing HIV treatment and medication adherence counseling at the same clinic where testing happens.
Going without PrEP because a testing clinic couldn't prescribe it, or losing days tracking down a separate provider for PEP, are real costs with real consequences. Champaign-Urbana Public Health District prescribes and manages both PrEP and PEP directly, with uninsured patients covered through dedicated funding.

STD stats & rates
How reported STI rates in Champaign County, the county that includes Mahomet, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~20% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#8 of 102 Illinois counties for chlamydia, a higher rate than 92% of the state
| Infection | Champaign County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 700.2 1,440 cases ▲ 26% | 557.7 | 492.2 |
| Gonorrhea | 227.1 467 cases ▲ 12% | 202.3 | 179.5 |
| Syphilis (P&S) | 8.3 17 cases ▼ 28% | 11.6 | 15.8 |
| Syphilis (early) | 8.8 18 cases ▼ 19% | 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 Champaign County, chlamydia has fallen from 759.2 to 700.2 per 100,000 (8%), gonorrhea has fallen from 382.3 to 227.1 per 100,000 (41%), and P&S syphilis has risen from 7.3 to 8.3 per 100,000 (14%).

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 Champaign County.
Local HIV snapshot
Champaign County HIV care continuum (2023)
Champaign County recorded 6.7 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Champaign County residents living with HIV, 85% are in care · 74.7% 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 Champaign County tests for syphilis.

Local resources & officials
Data & references
Local context
US 150 rolls through Mahomet as both East and West Oak Street, and the town it bisects feels deliberately settled: most households here are owner-occupied, most adults are married, and average household size tips toward three people or more. That kind of rooted, family-forward profile shapes daily life in ways that matter for health: schedules fill fast, and a medical errand that requires coordinating two working adults, kids, and a single car can quietly get deferred for months. That deferral risk is real even in a community where employment is strong and a majority of households clear six figures.
Comfortable incomes don't automatically translate to discretionary time, and the younger adults in the mix (people still in their late teens and twenties, forming relationships and moving through the years when STIs spread most easily) are often the ones least likely to carve out a clinic visit unless the path is genuinely short. Whether someone's coming off a shift and cutting back along Oak Street, or spending a Saturday afternoon near Barber Park, a same-week appointment is less of a logistical ask here than it would be in a larger, more spread-out community.
Getting there
Mahomet scores 12.03/20 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.
