STD stats & rates
How reported STI rates in Fillmore County, the county that includes Preston, compare with Minnesota 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.
#70 of 87 Minnesota counties for chlamydia, a higher rate than 20% of the state
| Infection | Fillmore County | Minnesota | United States |
|---|---|---|---|
| Chlamydia | 153.3 33 cases ▼ 60% | 379.5 | 492.2 |
| Gonorrhea | 4.6 1 cases ▼ 97% | 134.5 | 179.5 |
| Syphilis (P&S) | — no data | 8.7 | 15.8 |

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 Fillmore County, chlamydia has fallen from 188.4 to 153.3 per 100,000 (19%), gonorrhea has fallen from 33 to 4.6 per 100,000 (86%), and P&S syphilis has held roughly steady from 4.7 to 4.7 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 Fillmore County.
Local HIV snapshot
Fillmore County HIV care continuum (2022)
Fillmore County recorded 0 new HIV diagnoses per 100,000 (2022), against 6.7 statewide and 13.7 nationally. Among Fillmore County residents living with HIV, 85.7% are in care · 85.7% 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 Fillmore County tests for syphilis.

Data & references
Local context
The Milwaukee Elevator Co. still anchors Preston's modest downtown, a quiet landmark in a town where most households are owner-occupied and more than half of adults are married. The kind of place where health decisions tend to get folded into family rhythms rather than made on the fly. That stability shapes how people here think about routine care: it either becomes a shared household habit or it quietly falls to whoever has a free afternoon to drive out along the Historic Bluff Country Scenic Byway to the nearest clinic.
The people in their late teens and twenties for whom regular screening is most consequential and yet most easily deferred when a round trip eats up a chunk of a workday. Preston's workforce is largely employed and active, which is genuinely good news economically, but it also means that working hours are real hours, and a midweek appointment requires actual planning rather than spontaneity. Typical rents here stay well below state averages, which means cost is less often the sticking point than schedule and distance. Fillmore County's STI figures, visible elsewhere on this page, are the honest backdrop for any resident trying to gauge personal risk, and for someone living a few miles outside town, simply knowing which listed option has the most flexible hours is often the most practical thing to know.
Getting there
At 6.36/20 on the EPA walkability index, day-to-day errands in Preston 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 Minnesota 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 Minnesota, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Minnesota 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.
