St Clair County Health Department in Port Huron offers HIV, gonorrhea, chlamydia, syphilis, herpes, hepatitis C, and TB testing free of charge, with a sliding scale and Medicaid and private insurance accepted for other services. Walk-ins welcome, same-visit treatment for bacterial infections.
An unexpected invoice after testing is exactly where treatment gets delayed: someone opens it, does the math, and schedules the follow-up for a later date that never arrives. At St Clair County Health Department, every service carries no fee, so the moment of diagnosis stays connected to the moment of care.
As a Title X clinic, St Clair County Health Department provides legally confidential family planning services to minors. No parental disclosure required by law. For a teenager without a regular provider, or one paying out of pocket without a parent's knowledge, that standing protection changes what care is actually reachable.
Plenty of STI clinics cap their panel at HIV, syphilis, gonorrhea, and chlamydia. Herpes and hepatitis C get left for a separate appointment elsewhere. St Clair County Health Department tests for both, including hepatitis C, where a positive result can move directly into management without bouncing to another provider.

Walk-in STI clinics often cap their testing at the four bacterial and viral basics, leaving herpes and hepatitis as a separate errand. Henry Ford-GoHealth Urgent Care in Chesterfield runs the full extended panel (herpes, hepatitis A, B, and C, and TB) in the same visit, closing the gap before it becomes one.
Without interpretation support at the point of care, a missed nuance in a diagnosis conversation can mean an untreated infection or a follow-up that never happens. Henry Ford-GoHealth Urgent Care in Chesterfield keeps interpretation services available directly within the visit, so nothing critical gets lost between question and answer.

STD stats & rates
How reported STI rates in St. Clair County, the county that includes Marysville, compare with Michigan and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~20% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#34 of 83 Michigan counties for chlamydia, a higher rate than 59% of the state
| Infection | St. Clair County | Michigan | United States |
|---|---|---|---|
| Chlamydia | 218.3 349 cases ▼ 49% | 429.5 | 492.2 |
| Gonorrhea | 51.3 82 cases ▼ 66% | 152.2 | 179.5 |
| Syphilis (P&S) | 6.3 10 cases ▼ 25% | 8.4 | 15.8 |
| Syphilis (early) | 4.4 7 cases ▼ 49% | 8.7 | 16 |
| Syphilis (late/unknown) | 5.6 9 cases ▼ 57% | 13 | 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 St. Clair County, chlamydia has fallen from 229.5 to 218.3 per 100,000 (5%), gonorrhea has fallen from 90.4 to 51.3 per 100,000 (43%), and P&S syphilis has risen from 4.4 to 6.3 per 100,000 (43%).

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 St. Clair County.
Local HIV snapshot
St. Clair County HIV care continuum (2023)
St. Clair County recorded 8 new HIV diagnoses per 100,000 (2023), against 8.1 statewide and 13.7 nationally. Among St. Clair County residents living with HIV, 82.1% are in care · 72.3% 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 St. Clair County tests for syphilis.

Data & references
Local context
South Park sits close to the water, home to a mix of families and working couples who make up much of Marysville's steady, owner-occupier character. With nearly two-thirds of residents in the labor force and a meaningful share of households carrying the kind of schedule that leaves little slack between shifts, carving out time for a routine health appointment can compete with everything else a week demands. That reality matters especially for young adults still forming relationships, the years when STI rates run highest and when a test put off once tends to stay off the calendar.
Marysville's household profile leans toward stability, with most residents owning their homes and average households running close to three people, but stability doesn't dissolve time pressure. Someone driving Gratiot Boulevard home after a double shift isn't necessarily thinking about clinic hours, and the options listed here vary enough in schedule and cost structure to meet people at different points in that calculus. A wider spread of hours and locations means the right appointment is less a negotiation with the calendar and more a straightforward choice between several workable ones.
Getting there
At 7.67/20 on the EPA walkability index, day-to-day errands in Marysville 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 Michigan 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 Michigan, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Michigan 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.
