McHenry County Department of Health in Woodstock tests for gonorrhea, chlamydia, syphilis, HIV, hepatitis B and C, and TB, treats bacterial infections at the same visit, and operates on a sliding scale. With every service available at no fee.
For anyone managing STI care without an established primary-care relationship (paying cash, navigating gaps in coverage, or simply without a doctor to call) McHenry County Department of Health in Woodstock covers testing, treatment, and vaccines with no fee attached. That standing policy means the cost calculation never enters the room.
McHenry County Department of Health in Woodstock serves Spanish-speaking patients directly in Spanish, not through a side arrangement, but as part of the clinic's own capacity. For someone whose preferred language is Spanish, that means the medical conversation, the counseling, and the treatment discussion all happen without friction.
Skipping hepatitis screening at a standard STI visit often means a second appointment elsewhere, a gap between exposure and diagnosis, and delayed linkage to care. McHenry County Department of Health in Woodstock runs hepatitis B and C tests alongside gonorrhea, chlamydia, syphilis, and HIV, so a single appointment closes that gap rather than opening one.

Community Health Partnerships of Illinois in Harvard runs appointments for gonorrhea, chlamydia, syphilis, and hepatitis testing, with same-visit treatment for bacterial infections confirmed on-site. Fees follow a sliding scale, and Medicare, Medicaid, and private insurance are all accepted. Spanish-language care is available.
Spanish at Community Health Partnerships of Illinois isn't routed through a secondary service: clinical staff conduct the appointment, collect history, explain results, and coordinate treatment directly in Spanish. That means prescriptions are written and instructions given in the same language the conversation started in.
Beyond gonorrhea, chlamydia, syphilis, and rapid or conventional HIV testing, Community Health Partnerships of Illinois runs dedicated hepatitis B and hepatitis C tests within the same appointment. Each result is generated and reviewed on-site, so clinical follow-up, including hepatitis B vaccination if indicated, happens without splitting the visit into separate referrals.

STD stats & rates
How reported STI rates in McHenry County, the county that includes Union, 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.
#73 of 102 Illinois counties for chlamydia, a higher rate than 28% of the state
| Infection | McHenry County | Illinois | United States |
|---|---|---|---|
| Chlamydia | 203 635 cases ▼ 64% | 557.7 | 492.2 |
| Gonorrhea | 26.5 83 cases ▼ 87% | 202.3 | 179.5 |
| Syphilis (P&S) | 3.8 12 cases ▼ 67% | 11.6 | 15.8 |
| Syphilis (early) | 1.3 4 cases ▼ 88% | 10.9 | 16 |
| Syphilis (late/unknown) | 3.2 10 cases ▼ 88% | 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 McHenry County, chlamydia has risen from 200.2 to 203 per 100,000 (1%), gonorrhea has fallen from 30.6 to 26.5 per 100,000 (13%), and P&S syphilis has fallen from 3.9 to 3.8 per 100,000 (3%).
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 McHenry County.
Local HIV snapshot
McHenry County HIV care continuum (2023)
McHenry County recorded 3.4 new HIV diagnoses per 100,000 (2023), against 14.7 statewide and 13.7 nationally. Among McHenry County residents living with HIV, 76.9% are in care · 68.2% 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 McHenry County tests for syphilis.

Local resources & officials
Data & references
Local context
Prairie View Estates carries the quiet rhythm of a town where most households have put down roots: the majority of residents own their homes, and the average household runs closer to three people than two. That kind of stability shapes daily life in Union, but it can also mean that personal health appointments get crowded out by the logistics of managing a working family. With nearly three-quarters of adults in the labor force and unemployment low, most people here are simply busy, and a Tuesday afternoon clinic slot can feel like a luxury when schedules are already full.
That busyness hits hardest for younger adults, people in their late teens and twenties who are navigating new relationships, often without the scheduling flexibility that comes with more established careers. A notable share of Union households bring in solid incomes, which can create a false sense that routine care is somehow already handled, but STI screening sits outside most people's regular calendars regardless of earnings. From McHenry County Historical Society and Museum, the nearest option listed here is worth pulling up before you leave the parking lot.
Getting there
At 7.17/20 on the EPA walkability index, day-to-day errands in Union 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 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.
