STD stats & rates
How reported STI rates in Carroll County, the county that includes Lanark, 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.
#97 of 102 Illinois counties for chlamydia, a higher rate than 5% of the state
| Infection | Carroll County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 109.5 17 cases ▼ 80% | 557.7 | 492.2 |
| Gonorrhea | 38.6 6 cases ▼ 81% | 202.3 | 179.5 |
| Syphilis (P&S) | 6.4 1 cases ▼ 45% | 11.6 | 15.8 |
| Syphilis (early) | 6.4 1 cases ▼ 41% | 10.9 | 16 |

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 Carroll County, chlamydia has fallen from 267.5 to 109.5 per 100,000 (59%), gonorrhea has risen from 12.7 to 38.6 per 100,000 (204%), and P&S syphilis has held roughly steady from 6.4 to 6.4 per 100,000.

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 Carroll County.
Local HIV snapshot
Carroll County HIV care continuum (2023)
Carroll County recorded 0 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among Carroll County residents living with HIV, 77.8% 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 Carroll County tests for syphilis.

Local resources & officials
Data & references
Local context
Lanark's economy turns on agriculture and small manufacturing, work that demands steady hands and reliable schedules. That rhythm of routine maintenance and upkeep extends naturally into health. STI screening in and around Lanark fits into the practical mindset of residents who understand that regular checkups, like equipment inspections, catch problems early and keep life on track. Many people here are rooted in the same community for years, raising families and owning homes along Chambers Road and the stretches near IL 73. That stability means screening stays between you and the clinic; a test result doesn't ripple through town gossip.
The affordability that drew people to stay also means testing won't strain a budget already stretched between mortgage and fuel. Young adults, from late teens into their thirties, make up a significant part of Lanark's working population. For them, confidential access to testing is straightforward and practical, much like any other health need. Clinics and providers listed on this page understand that screening is routine, not shameful, and that getting answers fast lets you move forward without delay.

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.
