Planned Parenthood South Texas in Brownsville delivers STI testing (chlamydia, gonorrhea, syphilis, herpes, and rapid HIV) on a sliding-scale fee with same-visit treatment for bacterial infections, by appointment, with the full conversation conducted in Spanish.
When a clinic can't deliver STI care in Spanish, the consequence is real: nuance gets lost, questions go unasked, and follow-through suffers. At Planned Parenthood South Spanish isn't an accommodation, it's the language the appointment actually runs in, from the clinical conversation to treatment decisions.
Many clinics providing STI care aren't structured to offer confidential family planning to minors, that requires Title X designation and the legal framework that comes with it. Planned Parenthood South Texas carries that designation, meaning minors can access those services with the confidentiality Title X law requires.
Planned Parenthood South Texas prescribes all three current evidence-based prevention tools: PrEP for ongoing HIV prevention, PEP, and doxycycline post-exposure prophylaxis (DoxyPEP) for bacterial STI prevention. Meaning someone managing layered risk doesn't need to split care across multiple providers.

STD stats & rates
How reported STI rates in Cameron County, the county that includes South Padre Island, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~17% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#20 of 254 Texas counties for chlamydia, a higher rate than 92% of the state
| Infection | Cameron County | Texas | United States |
|---|---|---|---|
| Chlamydia | 604.6 2,580 cases ▲ 23% | 491.9 | 492.2 |
| Gonorrhea | 84.1 359 cases ▼ 52% | 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 Cameron County, chlamydia has risen from 369.8 to 604.6 per 100,000 (63%), gonorrhea has risen from 69.1 to 84.1 per 100,000 (22%), and P&S syphilis has risen from 2.4 to 7.5 per 100,000 (213%).

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 Cameron County.
Local HIV snapshot
Cameron County HIV care continuum (2023)
Cameron County recorded 18.4 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Cameron County residents living with HIV, 71% 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 Cameron County tests for syphilis.

Local context
Mornings along Padre Boulevard often mean a walk to the lighthouse or a coffee run before the day heats up, the kind of rhythm that makes South Padre Island feel like home to people who've chosen to stay. That same sense of knowing your surroundings extends to health care here. Confidential STI testing is available in and around South Padre Island through clinics and providers listed on this page, and the straightforward process means you can fit screening into a regular week without fanfare or explanation to anyone else. Young adults living here, whether they've recently arrived or grown up on the Island, tend to approach sexual health the way they approach most things: directly and without delay. Testing happens quietly; results remain yours alone.
The testing sites accessible from South Padre Island accommodate that preference, with staff trained to treat screening as routine rather than remarkable. The Island's character as a place where people build lives, not just pass through, means residents often think long-term about their health.

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.
