Tests offered
HealthFirst in Baraboo pairs same-visit treatment for bacterial STIs (gonorrhea, chlamydia, syphilis) with testing across a six-pathogen panel, all on a sliding-scale fee accepted alongside Medicaid and private insurance. Appointments are required, and HPV vaccination is available on-site.
HealthFirst offers interpretation services for non-English languages, which means a patient's reported symptoms and sexual history reach the clinician with precision. The kind of accuracy that shapes which tests get ordered and whether treatment starts the same day.
HealthFirst carries both PrEP and PEP prescribing in-house, which is the answer for anyone without a regular provider who needs ongoing HIV prevention medication. No separate specialist, no second appointment to initiate a prescription. Sliding-scale fees apply to these services as they do across the clinic.
Beyond gonorrhea, chlamydia, syphilis, and HIV, HealthFirst tests for herpes. A sixth pathogen that changes the clinical picture and the conversation about transmission. That single addition means a visit can produce answers where a narrower panel would leave questions open.

University of Wisconsin in Madison takes walk-in visits and covers the full bacterial and viral panel (gonorrhea, chlamydia, syphilis, herpes, hepatitis B and C, and HIV) with same-visit treatment for bacterial infections, sliding-scale fees, and direct care in American Sign Language, Chinese, French, Haitian Creole, and more.
Clinics that rely solely on on-demand interpretation services create a lag between patient and provider that erodes nuance. University of Wisconsin staffs or arranges direct care in American Sign Language, Chinese, French, and Haitian Creole, among others, so the clinical conversation happens in full, not in summary.
Ryan White Program funding at University of Wisconsin means HIV care doesn't stop at a positive result: it extends through ongoing medical treatment and medication adherence counseling, with costs covered or reduced for eligible patients regardless of insurance status.
University of Wisconsin carries both PrEP and PEP, and maintains a dedicated funding stream for uninsured patients seeking PrEP. Meaning the preventive medication itself, not just the consultation, is financially reachable for people without coverage.

STD stats & rates
How reported STI rates in Sauk County, the county that includes Prairie du Sac, compare with Wisconsin and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#10 of 72 Wisconsin counties for chlamydia, a higher rate than 86% of the state
| Infection | Sauk County | Wisconsin | United States |
|---|---|---|---|
| Chlamydia | 351.9 232 cases ▼ 17% | 422.8 | 492.2 |
| Gonorrhea | 25.8 17 cases ▼ 78% | 118.5 | 179.5 |
| Syphilis (P&S) | 3 2 cases ▼ 67% | 9.1 | 15.8 |
| Syphilis (early) | 3 2 cases ▼ 52% | 6.2 | 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 Sauk County, chlamydia has risen from 305.6 to 351.9 per 100,000 (15%), gonorrhea has fallen from 62.3 to 25.8 per 100,000 (59%), and P&S syphilis has fallen from 4.6 to 3 per 100,000 (35%).

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 Sauk County.
Local HIV snapshot
Sauk County HIV care continuum (2023)
Sauk County recorded 10.7 new HIV diagnoses per 100,000 (2023), against 5.1 statewide and 13.7 nationally. Among Sauk County residents living with HIV, 84.3% are in care · 84.3% 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 Sauk County tests for syphilis.

Data & references
Local context
The work week here runs steady: manufacturing jobs, agricultural trades, construction crews, families managing school schedules and commutes. When health needs arise, they compete with that rhythm, which is why confidential STI screening in and around Prairie Du Sac matters as practical access, not afterthought. Young adults moving through their twenties and thirties, whether newly partnered or single, often find routine testing fits better into a schedule when clinics nearby remove the friction of travel or delay. The community's established households and working families value privacy in their medical lives. Testing providers listed on this page understand that confidentiality isn't negotiable here: results belong to you alone, with no surprise notifications to employers, partners, or family.
Clinics serving Prairie Du Sac and Sauk City respect that boundary as standard practice, not exception. What draws people to screening isn't crisis, it's the ordinary need to know. Whether you're in a new relationship, between partners, or simply keeping current with your health, the testing available in and around Prairie Du Sac runs on a straightforward premise: you can walk in, get answers, and walk out with your privacy intact. That accessibility, paired with a community where people tend to their own business, makes the step easier than you might expect.

Two things that actually depend on Wisconsin 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 Wisconsin, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Wisconsin 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.
