A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Every Service Here Carries Zero Cost
All services at Cameron County Public Health are provided at no charge, which means the same visit that turns up a bacterial infection can move directly into treatment without any billing conversation in between.
Spanish Is the Working Language Here

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.
Read full overviewShow less
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.
Minors Can Access Family Planning Confidentially
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.
DoxyPEP Alongside PrEP and PEP
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.

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.

Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
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.

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.

Confidentiality & consent in TexasMinor consent and partner treatment (EPT) under state law, plus how to test privately
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).
Can a minor consent on their own?
In Texas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
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.
