Marion County Health Department in Salem runs STI care through the county public health infrastructure, which means appointments are required but the full panel (HIV, syphilis, gonorrhea, chlamydia, hepatitis A, B, and C, and TB) is available on a sliding scale, with same-visit treatment for bacterial infections, and all services at no fee.
All services at Marion County Health Department are provided at no charge, which means the cost of the visit never shapes which tests a patient accepts or which follow-up they pursue. The full scope of care (testing, treatment, vaccines, counseling) stays available without financial filtering.
Beyond the standard bacterial and HIV tests, Marion County Health Department tests for hepatitis A, B, and C, and offers hepatitis A and adult hepatitis B vaccination on-site. Catching hepatitis C infection and having vaccine access for A and B in the same appointment means liver-health screening doesn't require a separate clinical relationship.

Southern Illinois Healthcare Foundation in Salem requires an appointment, so call ahead, but that single visit covers gonorrhea, chlamydia, syphilis, and HIV on a sliding-scale fee open to everyone, with same-visit treatment for bacterial infections and Spanish-language care available.
Plenty of STI clinics run four tests and send patients elsewhere for anything more specific. Southern Illinois Healthcare Foundation tests for herpes, hepatitis A, hepatitis B, and hepatitis C alongside the standard bacterial and HIV screens. Meaning one appointment can account for infections that often go undetected simply because they weren't on the menu.
Many clinics manage Spanish-speaking patients through workarounds that keep the actual provider conversation at arm's length. At Southern Illinois Healthcare Foundation, Spanish is available as a direct language of care, so the conversation about symptoms, history, and next steps happens without anything lost between patient and clinician.

STD stats & rates
How reported STI rates in Marion County, the county that includes Odin, 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.
#28 of 102 Illinois counties for chlamydia, a higher rate than 73% of the state
| Infection | Marion County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 368.1 135 cases ▼ 34% | 557.7 | 492.2 |
| Gonorrhea | 87.3 32 cases ▼ 57% | 202.3 | 179.5 |
| Syphilis (P&S) | — no data | 11.6 | 15.8 |
| Syphilis (early) | 8.2 3 cases ▼ 25% | 10.9 | 16 |
| Syphilis (late/unknown) | 10.9 4 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 Marion County, chlamydia has fallen from 532.7 to 368.1 per 100,000 (31%), gonorrhea has fallen from 251.8 to 87.3 per 100,000 (65%), and P&S syphilis has risen from 5.3 to 5.4 per 100,000 (2%).

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 Marion County.
Local HIV snapshot
Marion County HIV care continuum (2023)
Marion County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Marion County residents living with HIV, 66.7% are in care · 66.7% 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 Marion County tests for syphilis.

Data & references
Local context
West Poplar Street tells you a lot about Odin before you've even turned off US 50: modest homes with deep lots, a town where three-quarters of residents own the roof over their heads and have for years. That stability shapes the community in real ways: households here tend to be larger, often multigenerational, and nearly half of adults are married, which means sexual health decisions ripple through established relationships, not just new ones. Yet beneath that settled surface, unemployment runs notably high, and with well under half the working-age population currently employed, household budgets, even those with low rent, get stretched thin.
Younger adults in their late teens and twenties make up a meaningful slice of the population here, and for people still navigating early careers in a tight local economy, the combination of limited flexible hours and real out-of-pocket costs can quietly turn a straightforward errand into something that keeps getting postponed. The closest ones are worth checking before assuming the drive is long, pulling up the clinic card on this page and confirming same-week availability is the most direct thing someone on West Poplar Street can do today.
Getting there
At 4.68/20 on the EPA walkability index, day-to-day errands in Odin generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
