DeKalb County Health Department anchors STI care within DeKalb's public health infrastructure, covering gonorrhea, chlamydia, syphilis, and rapid or conventional HIV testing on a sliding-scale fee accepted alongside Medicaid and insurance. Appointments are required, bacterial infections are treated same visit, and Spanish-language care is available.
The clinic delivers STI care in Spanish, not routed through a scheduling workaround, but as a standing service. For someone navigating treatment decisions, understanding a diagnosis, or following through on prevention, that means the conversation happens with full precision from the first question to the final prescription.
Ryan White funding means the clinic's HIV services extend from initial testing into ongoing care and treatment management. For a patient without a regular provider, that continuity, diagnosis and long-term HIV care held within the same system, eliminates the gap between a result and what comes next.

Greater Family Health in Sycamore operates on a sliding scale accepting Medicaid, Medicare, and private insurance, and runs a full panel (rapid and conventional HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B, hepatitis C, and TB) by appointment, with same-visit treatment for bacterial STIs and Spanish-language care on staff.
Greater Family Health carries both direct Spanish-language staff and broader interpretation services for other languages: meaning clinical conversations about medications, dosing, and follow-up happen in the language the provider is actually working in, not relayed through a secondary channel. That operational difference shapes what a patient retains when they leave.
Ryan White funding at Greater Family Health extends the entire arc of HIV care, from initial testing through ongoing antiretroviral treatment and medication adherence counseling, to people without adequate insurance or financial resources to cover it. That continuous funding means HIV management stays at one clinic rather than fragmenting across providers as circumstances change.
Without a clinic that prescribes both PrEP and PEP on-site, prevention often stalls at a referral that never gets followed through, and a missed PEP course or a delayed PrEP start carries real consequences. Greater Family Health writes both prescriptions directly, keeping prevention continuous rather than contingent on a separate provider.

STD stats & rates
How reported STI rates in DeKalb County, the county that includes Cortland, compare with Illinois and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~33% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#16 of 102 Illinois counties for chlamydia, a higher rate than 84% of the state

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 DeKalb County, chlamydia has fallen from 540.7 to 501.6 per 100,000 (7%), gonorrhea has fallen from 177.3 to 105.7 per 100,000 (40%), and P&S syphilis has risen from 3 to 6 per 100,000 (100%).

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 DeKalb County.
Local HIV snapshot
DeKalb County HIV care continuum (2023)
DeKalb County recorded 9.4 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among DeKalb County residents living with HIV, 77.3% are in care · 63.6% 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 DeKalb County tests for syphilis.

Data & references
Local context
IL 38, West Lincoln Highway, threads through Cortland as the practical spine of daily life, and the town that lines it skews toward stability: most households here are homeowners, half of adults are married, and the average household runs nearly four people. Health decisions in that kind of community often get made collectively, folded into schedules dense with work, school runs, and shared obligations rather than acted on solo and spontaneously. That household density matters more than it might first appear. With labor-force participation unusually high and unemployment near the floor, most working-age adults here are logging full weeks, which compresses the window for anything medical that isn't urgent.
Roughly four in ten households clear six figures, yet a monthly rent that clears $1,200 reminds anyone not in the ownership majority that discretionary spending has real limits. For younger adults still forming relationships, the cohort that historically drives STI incidence, both the packed schedule and the cost calculus shape whether screening happens at a convenient moment or gets indefinitely deferred. The options listed on this page, spread across the broader DeKalb County area, include enough variety in hours and fee structures to fit different situations, even when the nearest one requires a drive along the Tollway corridor. DeKalb County's STI figures are what they are, and Cortland residents share that county context whether or not they think of themselves as particularly connected to it, which makes staying current on screening less a precaution than a reasonable read of local conditions.

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.
