STD stats & rates
How reported STI rates in Ste. Genevieve County, the county that includes St. Mary, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#103 of 115 Missouri counties for chlamydia, a higher rate than 10% of the state

| Chlamydia | 107.3 20 cases ▼ 78% | 498.6 | 492.2 |
| Gonorrhea | 26.8 5 cases ▼ 87% | 201.9 | 179.5 |
| Syphilis (P&S) | — no data | 21.5 | 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 Ste. Genevieve County, chlamydia has fallen from 173.2 to 107.3 per 100,000 (38%), gonorrhea has fallen from 48.7 to 26.8 per 100,000 (45%), and P&S syphilis has held roughly steady from 5.4 to 5.4 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 Ste. Genevieve County.

Ste. Genevieve County HIV care continuum (2023)
Ste. Genevieve County recorded 0 new HIV diagnoses per 100,000 (2023), against 10.6 statewide and 13.7 nationally. Among Ste. Genevieve County residents living with HIV, 75% are in care · 66.7% 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 Ste. Genevieve County tests for syphilis.

Data & references
Local context
US 61 threads through St. That drive calculates differently depending on where someone sits in St. Mary's economic picture. With more than four in five households owning their homes, many at valuations well below the state median, and fewer than a fifth renting at around $780 a month, this is a community where people tend to stay, budgets run lean, and discretionary time is rationed carefully. Just over half the adult population is in the labor force, meaning schedules can be either tightly structured around shift work or irregularly open, neither of which maps neatly onto clinic hours at a distance.
The share of younger adults here, the years when STIs circulate most actively and relationships are still taking shape, is modest, but that's precisely why low-barrier options matter: when the nearest site is already a highway trip away, even mild inconvenience compounds fast. Nearly half of St. Mary's adults are married, household sizes run above average, and Lick Hill anchors a community where family life is the dominant texture. Screening fits into that life as straightforwardly as any other health appointment, and options listed on this page give residents real choices about where and when to make it happen.
Getting there

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