STD stats & rates
How reported STI rates in Franklin County, the county that includes Union, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~31% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#61 of 115 Missouri counties for chlamydia, a higher rate than 47% of the state
| Infection | Franklin County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 219.9 234 cases ▼ 56% | 498.6 | 492.2 |
| Gonorrhea | 41.4 44 cases ▼ 79% | 201.9 | 179.5 |

| Syphilis (early) | 10.3 11 cases ▼ 17% | 12.4 | 16 |

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 Franklin County, chlamydia has risen from 215.9 to 219.9 per 100,000 (2%), gonorrhea has fallen from 86.9 to 41.4 per 100,000 (52%), and P&S syphilis has risen from 2.9 to 20.7 per 100,000 (614%).

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 Franklin 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.
Franklin County HIV care continuum (2023)
Among Franklin County residents living with HIV, 81% are in care · 74.6% 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 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 Franklin County tests for syphilis.

Local resources & officials
Data & references
Local context
Friendship Park sits at the quiet edge of a town where a meaningful share of residents rent rather than own, many of them younger adults in the years when new relationships, new partners, and changing circumstances make routine STI screening genuinely useful rather than optional. At $726 a month, rent here is modest enough that it rarely crowds out a clinic copay, but a household running close to three people on a single income still weighs every errand against the cost of time off work. That workforce reality matters. With nearly two in three Union residents actively employed and unemployment low, most people here are putting in full weeks, which means a clinic with flexible hours earns its place on the calendar in a way that a nine-to-five-only option simply does not.
The roughly four in ten households without the stability of two incomes or a partner's schedule to trade off against feel that pressure most directly, and those are often the same households where the under-35 crowd is figuring out what consistent healthcare access even looks like for them. The options appear on this page, covering sites in and around Union and into neighboring communities. For some Franklin County residents the nearest one is a genuine drive rather than a short errand, so checking hours before heading out saves a wasted trip and keeps screening from becoming another task that waits another week.
Getting there
At 8.4/20 on the EPA walkability index, day-to-day errands in Union generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
