STD stats & rates
How reported STI rates in Vigo County, the county that includes Riley, compare with Indiana and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~28% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#5 of 92 Indiana counties for chlamydia, a higher rate than 95% of the state
| Infection | Vigo County | Indiana | United States |
|---|---|---|---|
| Chlamydia | 569.9 605 cases ▲ 16% | 491 | 492.2 |
| Gonorrhea | 255.3 271 cases ▲ 77% | 144 | 179.5 |
| Syphilis (P&S) | 17 18 cases ▲ 95% | 8.7 | 15.8 |
| Syphilis (early) | 26.4 28 cases ▲ 178% | 9.5 | 16 |
| Syphilis (late/unknown) | 15.1 16 cases ▼ 1% | 15.2 | 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 Vigo County, chlamydia has fallen from 598.2 to 569.9 per 100,000 (5%), gonorrhea has fallen from 323.1 to 255.3 per 100,000 (21%), and P&S syphilis has risen from 6.6 to 17 per 100,000 (158%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Vigo County.
Local HIV snapshot
Vigo County HIV care continuum (2023)
Vigo County recorded 11 new HIV diagnoses per 100,000 (2023), against 11.7 statewide and 13.7 nationally. Among Vigo County residents living with HIV, 63.8% are in care · 58.5% 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 Vigo County tests for syphilis.

Data & references
Local context
SR 46 connects Riley to the nearest testing options listed on this page, a drive that takes real time when you factor in a work schedule already stretched thin by the town's employment picture. With unemployment notably elevated and fewer than six in ten residents in the labor force, the households that are working tend to be working hard, and a clinic visit that requires half a day off carries genuine weight. That cost-of-time pressure lands differently depending on where you sit in Riley's housing picture. Nearly three-quarters of residents own their homes, many of them long-settled families near Trimmer Hill and Sanford Hill, while the quarter who rent pay over a thousand dollars a month against home values that are modest even by rural Indiana standards. For that renting quarter, a bill from an unplanned health visit competes with rent in a way it simply doesn't for owners with locked-in costs.
The options listed on this page include sliding-scale and low-cost appointments, which matters here more than the listings alone suggest. Riley's average household runs just over three people, and nearly half of adults are married. Meaning a positive result rarely stays a private matter. For the younger adults in their late teens and twenties, still forming those households and relationships, a straightforward test is less an event than a practical step that fits the same practical town they already live in.
Getting there
At 4.15/20 on the EPA walkability index, day-to-day errands in Riley 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 Indiana 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 Indiana, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Indiana 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.
