Available testing centers
8 testing options are listed for Rio Bravo, TX. The nearest, Gateway Community Health Center, is about 5.7 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Gateway Community Health Center in Laredo runs STI testing and same-visit treatment for bacterial infections on a sliding-scale fee that applies to everyone, with appointments required, and it serves patients in American Sign Language, Chinese, French, and Haitian Creole.
Gateway offers direct care in eight languages: American Sign Language, Chinese, French, Haitian Creole, Portuguese, Spanish, Tagalog, and Vietnamese. That range means clinical conversations about exposure history, treatment adherence, and prevention happen in the language a provider actually delivers care in, not through a relay.
Many STI clinics test but leave HIV prevention prescribing to outside providers. Gateway writes and manages both PrEP and PEP on-site, so ongoing HIV prevention is a clinical service here rather than a separate referral path.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Gateway tests for herpes and hepatitis A, B, and C in the same visit, which means infections that frequently share transmission routes with bacterial STIs get caught in one appointment rather than requiring a second.

For a patient whose primary language is Spanish, care at City of Laredo Health Department unfolds in that language at every step: history, results, treatment instructions, and counseling.

Ryan White funding at City of Laredo Health Department means a positive HIV result doesn't end the clinical relationship: it deepens it, with medication adherence education and ongoing HIV medical treatment available through the same program that caught it.

Gateway Community Health Center-West Side Clinic, in Laredo, adjusts fees to each patient's income, ensuring no one is turned away for inability to pay. Walk-ins are welcome for STI screening that covers syphilis, gonorrhea, and chlamydia under its federally qualified health center standing.

Pillar in Laredo covers HIV, syphilis, gonorrhea, chlamydia, and hepatitis C on a sliding-scale fee, with HIV testing and STI testing available at no charge, accepts insurance, treats bacterial infections the same visit, and takes walk-ins.
Sliding-scale clinics typically still land some patients with a bill at checkout. At Pillar, the floor is zero: no service carries a charge, regardless of income or coverage, making the sliding scale a guarantee rather than a variable.
Pillar prescribes and manages both PrEP and PEP directly, which means a patient building a long-term prevention strategy and one needing a time-sensitive response after an exposure are both handled within the same clinic relationship.
A bare-bones STI panel stops at the four bacterial and viral staples. Pillar adds hepatitis C to that list, catching an infection that shares transmission routes with the rest but often gets screened elsewhere only on request.

STD stats & rates
How reported STI rates in Webb County, the county that includes Rio Bravo, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~33% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#49 of 254 Texas counties for chlamydia, a higher rate than 81% of the state
| Infection | Webb County | Texas | United States |
|---|---|---|---|
| Chlamydia | 474.1 1,276 cases ▼ 4% | 491.9 | 492.2 |
| Gonorrhea | 87.3 235 cases ▼ 51% | 176.4 | 179.5 |
| Syphilis (P&S) | 16.7 45 cases ▲ 11% | 15 | 15.8 |
| Syphilis (early) | 20.8 56 cases ▼ 21% | 26.4 | 16 |
| Syphilis (late/unknown) | 55 148 cases ▲ 24% | 44.3 | 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 Webb County, chlamydia has risen from 387.1 to 474.1 per 100,000 (22%), gonorrhea has risen from 52.4 to 87.3 per 100,000 (67%), and P&S syphilis has risen from 2.6 to 16.7 per 100,000 (542%).

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 Webb County.
Local HIV snapshot
Webb County HIV care continuum (2023)
Webb County recorded 17.1 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Webb County residents living with HIV, 59.2% are in care · 52.5% 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 Webb County tests for syphilis.

Local resources & officials
Data & references
Local context
El Cenizo shares more than a boundary with Rio Bravo: the two communities share the kind of daily rhythm where most households are large, multigenerational, and deeply rooted. With nearly three-quarters of residents owning their homes and an average household pushing close to five people under one roof, this is a place where stability and density coexist: grown children living alongside parents, cousins sharing space, a social fabric stitched tight across extended families. That structure matters for sexual health, because people in their late teens and twenties, a substantial slice of Rio Bravo's population, are often navigating new relationships within households where private health decisions can feel complicated to discuss, let alone act on.
Labor-force participation here is modest, and unemployment runs noticeably higher than state norms, which means many residents juggle irregular schedules or limited income. At a typical rent of $655 and a median home value that reflects just how modestly most families build wealth, a costly clinic visit can genuinely compete with rent week. The options listed on this page include sliding-scale and low-cost services, worth filtering for before you commit to the drive.
Getting there
At 6.25/20 on the EPA walkability index, day-to-day errands in Rio Bravo 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 Texas 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 Texas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Texas 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.
