Mercyin Saint Louis pairs same-visit treatment for bacterial STIs like chlamydia and gonorrhea with a panel that extends to herpes, hepatitis A, B, and C, and TB: all on a fee-based, insurance- and Medicare-accepted sliding scale. Appointments are required.
Mercycarries PrEP and PEP as standing clinical services, meaning someone without a primary care physician, or one whose doctor doesn't prescribe HIV prevention medication, can access both here. No separate referral chain is needed to get the prescription initiated or maintained.
When a hepatitis C test comes back reactive at Mercy, treatment begins at the same location, which means the path from diagnosis to a prescription doesn't cross into a separate specialty practice or require scheduling at a different facility.
Mercy's clinical staff runs herpes and hepatitis A, B, and C testing alongside syphilis, gonorrhea, chlamydia, and HIV. Infections that require either specific physician orders or dedicated lab pathways to include. TB screening is also available, reflecting a panel built for broader infectious-disease coverage rather than the minimum four.

Mercy-GoHealth Urgent Care in Creve Coeur tests for gonorrhea, chlamydia, herpes, hepatitis A, B, and C, and TB, treating bacterial infections the same visit; fees run on a sliding scale accepted by Medicaid and most insurers, with walk-ins welcome and interpretation services available.
Mercy-GoHealth carries interpretation services for non-English languages as a standing part of care: meaning anyone whose primary language isn't English can navigate symptoms, understand a diagnosis, and confirm a treatment plan without a separate coordination step or a compromised conversation.
Many urgent-care and STI clinics test for gonorrhea, chlamydia, HIV, and syphilis, then stop. Leaving herpes and hepatitis to a specialist or a second visit. Mercy-GoHealth runs herpes and hepatitis A, B, and C testing directly, so a single appointment covers exposures that a narrower panel would miss entirely.

STD stats & rates
How reported STI rates in St. Louis County, the county that includes Westwood, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~14% 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
South Lindbergh Boulevard cuts through a community where the overwhelming majority of residents own the homes they live in, often for decades, and nearly two-thirds of households are married couples raising children together. That settled, high-equity profile is real, but it sits alongside an unemployment rate that's quietly elevated, meaning some younger adults in their late teens and twenties here are navigating job instability at the same moment they're forming new relationships and managing their own healthcare for the first time. When most people around you are long-rooted homeowners with established routines and family doctors, routine STI screening can feel like something that belongs to a different kind of life. Even though the years when people are most likely to encounter new partners are precisely the years it matters most.
What makes Westwood's situation genuinely distinctive is that two-thirds of households clear six figures, yet cost alone rarely explains whether screening actually happens. Schedule and proximity do. The unemployment picture means not everyone has employer-based coverage or a predictable calendar, and a younger adult between jobs may have more time but less financial confidence to act.
Getting there
At 9.18/20 on the EPA walkability index, day-to-day errands in Westwood 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.
