STD stats & rates
How reported STI rates in Jefferson County, the county that includes Arnold, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#55 of 115 Missouri counties for chlamydia, a higher rate than 52% of the state
| Infection | Jefferson County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 237.9 550 cases ▼ 52% | 498.6 | 492.2 |
| Gonorrhea | 73.1 169 cases ▼ 64% | 201.9 | 179.5 |
| Syphilis (P&S) | 11.2 26 cases ▼ 48% | 21.5 | 15.8 |
| Syphilis (early) | 6.1 14 cases ▼ 51% | 12.4 | 16 |
| Syphilis (late/unknown) | 17.3 40 cases ▼ 49% | 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 Jefferson County, chlamydia has risen from 218.3 to 237.9 per 100,000 (9%), gonorrhea has fallen from 94.4 to 73.1 per 100,000 (23%), and P&S syphilis has risen from 4.4 to 11.2 per 100,000 (155%).

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 Jefferson 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.
Jefferson County HIV care continuum (2023)
Jefferson County recorded 3.1 new HIV diagnoses per 100,000 (2023), against 10.6 statewide and 13.7 nationally. Among Jefferson County residents living with HIV, 82.7% are in care · 73.3% 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 Jefferson County tests for syphilis.

Local resources & officials
Data & references
Local context
Maxville skews toward long-settled families, the kind of households where two working adults split a schedule that rarely lines up with standard clinic hours. That pattern holds across much of Arnold: most residents own their homes, households here run larger than the national average, and a slim majority of adults are married, which means childcare, shift overlap, and commuting along Jeffco Boulevard or down to I-55 often crowd out midweek appointments before anyone consciously decides to skip them.
That scheduling reality matters most for people in their late teens and twenties, who account for a meaningful slice of Arnold's population and represent the years when STIs circulate most readily and go most often undetected. With roughly three in ten households not clearing six figures and nearly five percent of the labor force currently between jobs, a testing option that carries no or low cost is not a minor convenience, it's often the factor that decides whether someone follows through at all.
Getting there
At 8.34/20 on the EPA walkability index, day-to-day errands in Arnold 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 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.
