Washington University School of Medicine in Saint Louis brings academic medical infrastructure to STI care: rapid and conventional HIV, syphilis, gonorrhea, chlamydia, and full hepatitis testing, with same-visit bacterial treatment, PrEP, DoxyPEP, and sliding-scale fees. Walk-ins welcome, all services at no fee.

Many clinics handle language by patching in a remote service that sits between patient and provider. Washington University School of Medicine staffs Spanish directly alongside broader interpretation services, so clinical conversations (history, treatment options, adherence counseling) happen without a layer of delay.
Ryan White funding at Washington University School of Medicine means a positive HIV result doesn't end the clinical relationship, it extends it. Medication adherence counseling, ongoing HIV/AIDS medical treatment, and care coordination are built into the same program that begins with the test.

SSM Health in Saint Louis tests for HIV, syphilis, gonorrhea, chlamydia, and all three hepatitis strains on a fee-and-insurance basis, with same-visit treatment for bacterial infections. Appointments are required, and Ryan White funding supports HIV care from first test through long-term management.
Ryan White funding at SSM Health sustains a structured HIV program where providers prescribe and monitor antiretroviral regimens, track viral load and CD4 counts over time, and maintain the clinical staffing to support patients from initial diagnosis through years of ongoing HIV/AIDS medical treatment. All within the same practice.
SSM Health prescribes PrEP and PEP directly, which means the medication decision and the prescription happen at the same appointment. Keeping the gap between risk assessment and an active prescription as short as a single visit.
Without on-site treatment, a hepatitis C diagnosis can stall into months of specialist wait times while the virus continues damaging liver tissue. SSM Health carries hepatitis C treatment directly, so a confirmed diagnosis moves to a treatment plan within the same clinical relationship rather than pausing at a referral handoff.

PrEP refills and follow-up monitoring stay within the same practice rather than bouncing between specialists.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Family Care Health Centers tests for herpes. A fifth infection that many clinics omit from their panels entirely. That single addition means patients leave with a more complete picture of their status from one appointment.

Vivent Health in Saint Louis provides free HIV, hepatitis B, hepatitis C, syphilis, gonorrhea, chlamydia, and herpes testing on a sliding-scale fee structure, with insurance and Medicaid accepted; gonorrhea and chlamydia are treated the same visit, and an appointment is required.
When cost interrupts care (the unpaid lab bill, the prescription left unfilled, the follow-up skipped) gaps open that compound quickly. At Vivent Health, every service on the menu, from testing through treatment to medication adherence counseling, carries no charge, so nothing between diagnosis and resolution goes unaddressed for financial reasons.
Vivent Health in Saint Louis maintains Spanish-language capability and broader interpretation services as standing clinical infrastructure, not a workaround arranged on request.

Vivent Health staffs HIV medical providers who initiate and monitor both PrEP and PEP directly: writing prescriptions, scheduling the required follow-up labs (HIV testing, kidney function, STI screening), and adjusting dosing as needed. PrEP for uninsured patients is available at no cost, and the clinical team manages ongoing adherence rather than handing off to an outside prescriber.

STD stats & rates
How reported STI rates in St. Louis city, the city that includes St. Louis, 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.
#1 of 115 Missouri counties for chlamydia, among the very highest in the state
| Infection | St. Louis city | Missouri | United States |
|---|---|---|---|
| Chlamydia | 1340.9 3,778 cases ▲ 169% | 498.6 | 492.2 |
| Gonorrhea | 809.9 2,282 cases ▲ 301% | 201.9 | 179.5 |
| Syphilis (P&S) | 50.8 143 cases ▲ 136% | 21.5 | 15.8 |
| Syphilis (early) | 41.2 116 cases ▲ 232% | 12.4 | 16 |
| Syphilis (late/unknown) | 89.1 251 cases ▲ 164% | 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 city, chlamydia has risen from 1219.9 to 1340.9 per 100,000 (10%), gonorrhea has fallen from 848.9 to 809.9 per 100,000 (5%), and P&S syphilis has risen from 46.8 to 50.8 per 100,000 (9%).

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 city.

St. Louis city HIV care continuum (2023)
St. Louis city recorded 43 new HIV diagnoses per 100,000 (2023), against 10.6 statewide and 13.7 nationally. Among St. Louis city residents living with HIV, 75.7% are in care · 64.5% 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 city tests for syphilis.

Local resources & officials
Data & references
Local context
Forest Park Avenue cuts through a city where most households rent rather than own, and that tenure reality shapes more than budgets. It shapes how people weigh discretionary health spending. With a majority of residents renting at relatively modest monthly costs, St. Louis households still carry real financial trade-offs, and for the roughly seven in ten adults in the workforce, a weekday clinic visit competes directly with shifts that can't always flex. The household picture here adds another layer.
Fewer than a third of adults are married, average households run above three people, and a meaningful share of those earners are supporting others on incomes that don't leave much cushion. For younger adults in their late teens and twenties, the years when STI risk is highest and routine screening is most consequential, those pressures are amplified. The neighborhoods threading along South Grand Boulevard and into Forest Park Southeast tend to skew younger and more transient, precisely the conditions where annual testing should be unremarkable rather than effortful. Getting tested near the Pulitzer Arts Foundation or along North Grand Boulevard is, for many residents, simply a matter of knowing the options exist.
Getting there
St. Louis scores 13.33/20 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.
