STD stats & rates
How reported STI rates in Sanilac County, the county that includes Port Sanilac, compare with Michigan 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.
#75 of 83 Michigan counties for chlamydia, a higher rate than 10% of the state
| Infection | Sanilac County | Michigan | United States |

| Gonorrhea | 12.4 5 cases ▼ 92% | 152.2 | 179.5 |

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 Sanilac County, chlamydia has fallen from 179.8 to 109 per 100,000 (39%), gonorrhea has fallen from 22.2 to 12.4 per 100,000 (44%), and P&S syphilis has held roughly steady from 2.5 to 2.5 per 100,000.
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 Sanilac County.
Local HIV snapshot
Sanilac County HIV care continuum (2023)
Sanilac County recorded 0 new HIV diagnoses per 100,000 (2023), against 8.1 statewide and 13.7 nationally. Among Sanilac County residents living with HIV, 80% are in care · 60% 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 Sanilac County tests for syphilis.

Data & references
Local context
South Ridge Street runs close to most of Port Sanilac's residential fabric, where a predominantly homeowning town (mortgages paid, households settled) can still harbor a quieter strain of health inertia: the assumption that stability means risk has passed. Yet younger adults navigating early relationships don't shed STI exposure because their neighbors have owned their homes for decades, and in a community where more than half the adult population isn't in the active labor force, the rhythms of daily life don't follow a predictable nine-to-five that makes scheduling anything easy. That labor-force reality, combined with an unemployment rate that leaves some households financially stretched, puts the modest cost of a clinic visit in sharper focus. With a relatively small renter population and typical rents under eight hundred dollars, those who do rent are often budgeting tightly enough that unexpected medical fees become a genuine reason to delay.
The options listed on this page include sliding-scale and low-cost providers that absorb that hesitation. What changes everything here, though, is the town's near-total car dependence. There are no sidewalks linking Harbor Park to a clinic, no bus down M 25. Getting tested in and around Port Sanilac means planning a deliberate drive, which means the clinic's hours, not just its fees, determine whether screening actually happens for someone balancing an irregular schedule in a small lakeside town.
Getting there
At 4.06/20 on the EPA walkability index, day-to-day errands in Port Sanilac 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.
