STD stats & rates
How reported STI rates in St. Louis County, the county that includes Black Jack, compare with Missouri 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.
#5 of 115 Missouri counties for chlamydia, a higher rate than 96% of the state
| Infection | St. Louis County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 635.3 6,271 cases ▲ 27% | 498.6 | 492.2 |
| Gonorrhea | 294.7 2,909 cases ▲ 46% | 201.9 | 179.5 |
| Syphilis (P&S) | 16 158 cases ▼ 26% | 21.5 | 15.8 |
| Syphilis (early) | 10 99 cases ▼ 19% | 12.4 | 16 |
| Syphilis (late/unknown) | 30 296 cases ▼ 11% | 33.8 | 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. Louis County, chlamydia has risen from 603.8 to 635.3 per 100,000 (5%), gonorrhea has fallen from 339.5 to 294.7 per 100,000 (13%), and P&S syphilis has risen from 15.5 to 16 per 100,000 (3%).

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. Louis County.
Local HIV snapshot
Federal priority area: Missouri is one of the U.S. jurisdictions prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
St. Louis County HIV care continuum (2023)
St. Louis County recorded 14.7 new HIV diagnoses per 100,000 (2023), against 10.6 statewide and 13.7 nationally. Among St. Louis County residents living with HIV, 75.9% are in care · 65.4% 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. Louis County tests for syphilis.

Local resources & officials
Data & references
Local context
Black Jack's Florissant neighborhood carries the unhurried feel of a place where people have genuinely put down roots, driveways lined with the same cars for years, households that run large by most measures, neighbors who know each other's routines. That stability shapes daily life here, but it also creates a particular kind of health-access blind spot: when a community feels settled, routine screening can feel less urgent than it is, even as younger adults in their late teens and twenties, the years when STIs circulate most readily, move through those same streets and households. The economics add texture to that picture.
Unemployment here runs high enough that a meaningful share of working-age adults are managing stretched budgets, and with typical rents sitting at a level that absorbs a real chunk of a single paycheck, an out-of-pocket clinic visit can feel like a calculation rather than a given. The barrier is more about awareness than logistics. Testing options are listed on this page, several with flexible hours and low or no cost.
Getting there
Black Jack scores 11.7/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
