STD stats & rates
How reported STI rates in Clark County, the county that includes Casey, 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.
#58 of 102 Illinois counties for chlamydia, a higher rate than 43% of the state
| Infection | Clark County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 225.3 34 cases ▼ 60% | 557.7 | 492.2 |
| Gonorrhea | 92.8 14 cases ▼ 54% | 202.3 | 179.5 |
| Syphilis (P&S) | — no data | 11.6 | 15.8 |

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 Clark County, chlamydia has fallen from 232.9 to 225.3 per 100,000 (3%), gonorrhea has risen from 51.8 to 92.8 per 100,000 (79%), and P&S syphilis has held roughly steady from 6.5 to 6.5 per 100,000.
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 Clark County.
Local HIV snapshot
Clark County HIV care continuum (2023)
Clark County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Clark County residents living with HIV, 90.9% are in care · 90.9% 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 Clark County tests for syphilis.

Data & references
Local context
Route 40 cuts through Casey in minutes, which tells you something useful: a clinic visit from here means committing to a real drive, not a quick errand between stops. That distance calculus lands differently depending on how you're set up, and in a town where most residents own their homes at values well below the state median, and where typical rents sit comfortably under $750 a month, the financial pressure on any given household is real even if it's quieter than in bigger markets. Cost-sensitive decisions, including whether to schedule a screening, get weighed against that backdrop. The workforce picture adds another layer.
With nearly two-thirds of residents in the labor force and unemployment low, most adults here are putting in full weeks, which means the options listed on this page need to fit around actual working hours, not just exist in principle. Young adults in their late teens and twenties represent a meaningful slice of Casey, and for that group especially, a clinic that's reachable on a lunch break or a Saturday morning matters more than one with a good address. Casey's household profile (majority married, averaging between two and three people per home) means testing often touches more than one person. A routine screen for one partner is, practically speaking, a decision that involves two.
Getting there
At 5.92/20 on the EPA walkability index, day-to-day errands in Casey 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.
