Chicagoland Infectious Disease in Homewood runs a full bacterial and viral panel (gonorrhea, chlamydia, syphilis, rapid HIV, and hepatitis C) treating confirmed bacterial infections the same visit, on a sliding scale that extends to no fee. Appointments are required.
The sliding scale at Chicagoland Infectious Disease is structured so that the bottom tier carries no charge, no partial balance left over after the visit. That applies across testing, STI treatment, HIV/AIDS medical care, hepatitis B and C treatment, PrEP, PEP, DoxyPEP, and TB treatment alike.
Spanish-speaking patients at Chicagoland Infectious Disease work through their care (medication adherence counseling, prevention education, HIV test counseling) with staff who conduct those conversations in Spanish directly, so the clinical detail in treatment plans and dosing instructions lands without translation lag.
When only one or two prevention options live at the same address, the missing piece means another appointment, another intake, another delay before coverage is complete. Chicagoland Infectious Disease prescribes and manages PrEP, PEP, and DoxyPEP under the same roof, so the full prevention layer is assembled without sending patients elsewhere to close the gap.

STD stats & rates
How reported STI rates in Cook County, the county that includes Markham, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#5 of 102 Illinois counties for chlamydia, a higher rate than 95% of the state
| Infection | Cook County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 790 40,189 cases ▲ 42% | 557.7 | 492.2 |
| Gonorrhea | 319.7 16,265 cases ▲ 58% | 202.3 | 179.5 |
| Syphilis (P&S) | 17.4 884 cases ▲ 50% | 11.6 | 15.8 |
| Syphilis (early) | 19.3 982 cases ▲ 77% | 10.9 | 16 |
| Syphilis (late/unknown) | 41.1 2,091 cases ▲ 58% | 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 Cook County, chlamydia has risen from 694.7 to 790 per 100,000 (14%), gonorrhea has fallen from 333.3 to 319.7 per 100,000 (4%), and P&S syphilis has fallen from 20.9 to 17.4 per 100,000 (17%).

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 Cook County.
Local HIV snapshot
Federal priority area: Cook County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Cook County HIV care continuum (2023)
Cook County recorded 24.7 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Cook County residents living with HIV, 88% know their status · 78% are in care · 60.8% 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 Cook County tests for syphilis.

Data & references
Local context
Dixie Highway at mid-morning carries a particular quiet (a few cars angling toward the I-294 on-ramp, a school bus looping back through the South Harvey streets) and most of the clinics listed here sit within a drive that barely outlasts a podcast segment. That proximity matters in a city where a large share of households support nearly four people on a single income, and where unemployment runs high enough that a missed half-day of work isn't a minor inconvenience but a real calculation. For younger adults, late teens through mid-twenties navigating new relationships and shifting living situations, that calculation tends to push appointments to the back of the queue unless the appointment is genuinely easy to reach and easy to afford.
Markham's ownership rate tells a quieter story too: nearly three-quarters of residents own their homes, which points toward rooted, longer-term households, yet the home values here mean those owners aren't sitting on wealth that cushions unexpected costs. Renters, meanwhile, absorb monthly rents that leave little room for out-of-pocket health spending. When cost is a real variable, knowing that listed clinics offer sliding-scale or no-cost visits changes whether screening actually happens this month or gets deferred.
Getting there
Markham scores 12.33/20 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.
