Sangamon County Department of Public Health in Springfield covers the full bacterial and viral panel (gonorrhea, chlamydia, syphilis, herpes, hepatitis C, TB, and rapid HIV) with all services provided at no fee, sliding-scale pricing, and both Medicaid and private insurance accepted; appointments are required, and same-visit treatment is available for bacterial STIs.
For anyone paying cash without a regular provider, Sangamon County Public Health's standing policy covers the entire visit (testing, same-visit bacterial treatment, vaccines, and PrEP) without a balance. No insurance is required to walk out with the same care as someone who has it.
Plenty of clinics handle Spanish-speaking patients through remote interpretation services, workable, but impersonal. Sangamon County Public Health delivers care directly in Spanish, so the clinical conversation happens in the room, not routed through a device on the counter.
Sangamon County Public Health prescribes both PrEP and PEP on-site, meaning the HIV-prevention medications themselves, not a forwarded request. PrEP requires ongoing HIV and kidney monitoring, and the clinic carries that longitudinal management in-house rather than splitting it across separate providers.

STD stats & rates
How reported STI rates in Sangamon County, the county that includes Chatham, 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.
#12 of 102 Illinois counties for chlamydia, a higher rate than 88% of the state
| Infection | Sangamon County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 590.7 1,143 cases ▲ 6% | 557.7 | 492.2 |
| Gonorrhea | 304.4 589 cases ▲ 50% | 202.3 | 179.5 |
| Syphilis (P&S) | 16 31 cases ▲ 38% | 11.6 | 15.8 |
| Syphilis (early) | 10.9 21 cases ≈ the state average | 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 Sangamon County, chlamydia has fallen from 728.8 to 590.7 per 100,000 (19%), gonorrhea has fallen from 448.7 to 304.4 per 100,000 (32%), and P&S syphilis has risen from 7.6 to 16 per 100,000 (111%).

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 Sangamon County.
Local HIV snapshot
Sangamon County HIV care continuum (2023)
Sangamon County recorded 11.5 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Sangamon County residents living with HIV, 83.6% are in care · 72.6% 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 Sangamon County tests for syphilis.

Data & references
Local context
Caldwell Farmstead anchors Chatham's older edge the way the community's character anchors its households: most residents here own their homes, most are married, and the average household runs to three people or more. Health decisions in that kind of town often get filtered through shared schedules, shared finances, and a sense that anything requiring a separate trip can wait until someone has a free afternoon that never quite arrives.
That household density matters for STI screening because Chatham's young adults, people in their late teens and twenties forming new relationships, move through a community where over four in ten households bring in six figures and employment is close to universal. The financial floor is relatively solid, yet cost and time still shape whether screening happens. A drive out along IL 4 toward one of the options listed on this page means coordinating with a partner's schedule, a child's pickup, or a shift that starts before most clinics open on a weekday. Woodside residents and anyone coming off North Main Street face the same basic calculus: the appointment has to fit inside a life that is already full.
Sangamon County's STI figures are visible elsewhere on this page, and they reflect patterns that don't spare smaller, owner-occupied communities. For someone living here, staying current with screening is simply part of knowing where the county actually stands, not where it seems to from the outside.
Getting there
At 8.79/20 on the EPA walkability index, day-to-day errands in Chatham 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.
