Fees & payment
Aunt Martha's Health Center West Joliet, in Joliet, earned its federally qualified designation by tying fees directly to household income: meaning sliding-scale STI screening for syphilis, gonorrhea, and chlamydia is available regardless of what someone can pay, and no appointment is required to get started.
Tests offered
Fees & payment
Will County Health Department in Joliet runs STI care through the infrastructure of a public health department: meaning the full panel of HIV, syphilis, gonorrhea, chlamydia, hepatitis B, hepatitis C, and herpes testing is available on a sliding scale, with same-visit treatment for bacterial infections, at no cost to patients.
When cost sits between a person and follow-through (a second visit, a prescription pickup, an HIV management appointment) care quietly falls apart. At Will County Health Department, every service, from the initial test to ongoing HIV and hepatitis C treatment, is provided at no fee, so cost never becomes the reason a condition goes unmanaged.
Will County Health Department conducts care directly in Spanish and Vietnamese, not routed through an outside service, but spoken by staff in the exam room. For someone managing PrEP adherence, navigating a hepatitis C treatment plan, or working through medication counseling, that means the clinical conversation happens in full, with nothing lost.
Will County Health Department prescribes and manages both PrEP and PEP in-house, which means a patient who starts prevention medication here stays with the same clinical team for ongoing monitoring, refills, and any needed adjustments. Continuity that keeps prevention from slipping.

STD stats & rates
How reported STI rates in Grundy County, the county that includes Diamond, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#83 of 102 Illinois counties for chlamydia, a higher rate than 19% of the state
| Infection | Grundy County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 179.2 96 cases ▼ 68% | 557.7 | 492.2 |
| Gonorrhea | 22.4 12 cases ▼ 89% | 202.3 | 179.5 |
| Syphilis (P&S) | — no data | 11.6 | 15.8 |
| Syphilis (early) | — no data | 10.9 | 16 |
| Syphilis (late/unknown) | 1.9 1 cases ▼ 93% | 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 Grundy County, chlamydia has fallen from 180.8 to 179.2 per 100,000 (1%), gonorrhea has fallen from 59 to 22.4 per 100,000 (62%), and P&S syphilis has risen from 1.9 to 5.7 per 100,000 (200%).

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 Grundy County.
Local HIV snapshot
Grundy County HIV care continuum (2021)
Grundy County recorded 0 new HIV diagnoses per 100,000 (2021), against 14.7 statewide and 13.7 nationally. Among Grundy County residents living with HIV, 57.9% are in care · 52.6% 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 Grundy County tests for syphilis.

Data & references
Local context
West Baltimore Street anchors a Diamond where most households are owner-occupied and more than half of adults are married: the kind of community where health decisions often get made as a family rather than alone, folded into conversations about schedules, budgets, and shared responsibilities. That household character shapes how people actually get around to routine care. With nearly three people per household on average and a labor-force participation rate that leaves very few adults on the sidelines, most residents are juggling work and family commitments simultaneously.
The renter third of Diamond, paying around a thousand dollars a month, carries real cost awareness into every healthcare choice, and the options listed on this page include low- and no-cost paths that fit that reality. Young adults in their late teens and twenties, present in meaningful numbers across neighborhoods like Shadow Lakes and Explorer Village, are precisely the people for whom straightforward, low-barrier access to testing matters most, since that stretch of life tends to involve the relationship changes that most benefit from routine screening. Grundy County's STI figures give residents genuine reason to stay current; for someone living along North Front Street or near Diamond Park, knowing those numbers apply locally, not just to distant metros, is reason enough to check when you last tested.
Getting there
At 6.23/20 on the EPA walkability index, day-to-day errands in Diamond 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.
