South Texas Family Planning and Health in Sinton weaves family planning infrastructure into its STI care, offering the full standard panel, same-visit bacterial treatment, and HPV, hepatitis A, and hepatitis B vaccines. All on a sliding scale, with walk-in access, at no fee to every patient.
Sliding-scale pricing usually means some patients pay and some don't. At South Texas Family Planning and Health, the scale bottoms out for everyone (testing, treatment, vaccines, counseling) none of it generates a charge, regardless of what a patient brings through the door.
When language services are patched in after the fact, the clinical conversation suffers: nuance gets lost, follow-up questions go unasked, and care stalls. South Texas Family Planning and Health delivers services directly in Spanish, with interpretation available for other languages, so nothing about a patient's care is filtered or delayed by a language gap.
The standard four-infection screen leaves hepatitis off the table entirely. South Texas Family Planning and Health tests for hepatitis A, B, and C in addition to gonorrhea, chlamydia, and HIV, so a single visit can surface infections that a narrower panel would simply miss.

Amistad Health in Robstown takes walk-in visits and covers gonorrhea, chlamydia, syphilis, and HIV testing in a single stop: with STI treatment, HPV and hepatitis vaccines, and sliding-scale fees that extend to Medicaid and Medicare. Care is delivered in Spanish.
Spanish-speaking patients without a regular provider elsewhere, and without the overhead of navigating a bilingual system, get their full visit, counseling, and treatment discussion conducted in Spanish as the primary language of care at Amistad Health, not a supplementary service layered on top.
Amistad Health prescribes and manages both PrEP and PEP directly: meaning the baseline HIV testing required before starting PrEP, ongoing monitoring visits, and prescription continuity all run through the clinic itself rather than requiring a separate prescribing physician.

STD stats & rates
How reported STI rates in San Patricio County, the county that includes Mathis, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~28% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#64 of 254 Texas counties for chlamydia, a higher rate than 75% of the state

| Chlamydia | 409 289 cases ▼ 17% | 491.9 | 492.2 |
| Gonorrhea | 120.3 85 cases ▼ 32% | 176.4 | 179.5 |

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 San Patricio County, chlamydia has fallen from 487.2 to 409 per 100,000 (16%), gonorrhea has fallen from 173.1 to 120.3 per 100,000 (31%), and P&S syphilis has fallen from 13.1 to 12.7 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 San Patricio County.
Local HIV snapshot
San Patricio County HIV care continuum (2022)
San Patricio County recorded 15.7 new HIV diagnoses per 100,000 (2022), against 20.2 statewide and 13.7 nationally. Among San Patricio County residents living with HIV, 82.9% are in care · 75.6% 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 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 San Patricio County tests for syphilis.

Data & references
Local context
With homeownership well above half the population and rents sitting unusually low, housing costs aren't the barrier; it's time, transportation, and whether a testing appointment competes with a work shift in a labor market where fewer than half of residents are actively working and those who are can't easily step away mid-week. Those pressures land unevenly on younger adults, the late-teens-and-twenties crowd that, nationally, accounts for the bulk of new STI diagnoses. In San Patricio County, where rates are tracked and visible on this page, that reality has a local shape.
Getting tested when TX 359 is your only route and the options listed here may be a county away isn't simply inconvenient; it's the kind of logistical weight that accumulates until months pass between intentions and action. Mathis households also run larger than the national average and skew toward families rather than solo renters. For people navigating shared living situations and shifting relationships (whether newly partnered, between relationships, or somewhere in between) routine screening is less a health-department abstraction than a quiet, practical thing a household member quietly just handles.
Getting there
At 4.91/20 on the EPA walkability index, day-to-day errands in Mathis 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.
