STD stats & rates
How reported STI rates in Hancock County, the county that includes Plymouth, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~16% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#61 of 102 Illinois counties for chlamydia, a higher rate than 40% of the state
| Infection | Hancock County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 215.3 37 cases ▼ 61% | 557.7 | 492.2 |
| Gonorrhea | 34.9 6 cases ▼ 83% | 202.3 | 179.5 |
| Syphilis (P&S) | — no data | 11.6 | 15.8 |
| Syphilis (early) | — no data | 10.9 | 16 |
| Syphilis (late/unknown) | 5.8 1 cases ▼ 78% | 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 Hancock County, chlamydia has fallen from 255.4 to 215.3 per 100,000 (16%), and gonorrhea has fallen from 39.7 to 34.9 per 100,000 (12%).

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 Hancock County.
Local HIV snapshot
Hancock County HIV care continuum (2023)
Hancock County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Hancock County residents living with HIV, 50% are in care · 50% 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 Hancock County tests for syphilis.

Data & references
Local context
People land in Plymouth for work at the nuclear station, for family roots that go back generations, or simply because the cost of living lets them breathe. Young adults especially, those in their late teens through their thirties, often find themselves here longer than expected, building lives in a place where everyone's connected but privacy still exists if you know where to look. That's when questions about sexual health stop being abstract and become personal. STI testing in and around Plymouth is available through clinics and providers listed on this page, and the confidentiality that matters most to you is built into how these services work.
Results don't circulate through town gossip or show up in places they shouldn't. The testing itself is straightforward and the turnaround on results means you're not left waiting in uncertainty for weeks. What matters here is that seeking a screening doesn't require a dramatic trip or an explanation to half the county. Whether you're between partners, checking in after a casual encounter, or simply making routine health part of your rhythm, the services exist quietly and professionally.
The people running them understand that in a town like this, trust and discretion aren't luxuries. They're the foundation that lets someone actually show up.

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.
