The testing menu at South Texas Family Planning and Health includes herpes, hepatitis B antibody testing, and a hepatitis C test alongside the core bacterial and viral panel: nine distinct tests in total, each ordered and resulted on-site rather than split across separate referrals.

Spanish is a primary service language at South Texas Substance Abuse Recovery Services, meaning counseling, medication adherence education, and prevention conversations run directly in Spanish without relay. The clinical relationship, not just the intake form, functions in that language.
Substance-use treatment runs alongside STI testing and medication adherence counseling at this Corpus Christi site, so a positive result can be met with support for the behavioral and medical factors at once. No separate referral chain required to begin both conversations.

STD stats & rates
How reported STI rates in Nueces County, the county that includes Port Aransas, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~16% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#11 of 254 Texas counties for chlamydia, a higher rate than 96% of the state
| Infection | Nueces County | Texas | United States |
|---|---|---|---|
| Chlamydia | 675.6 2,380 cases ▲ 37% | 491.9 | 492.2 |
| Gonorrhea | 263.4 928 cases ▲ 49% | 176.4 | 179.5 |
| Syphilis (P&S) | 23.6 83 cases ▲ 57% | 15 | 15.8 |
| Syphilis (early) | 16.7 59 cases ▼ 37% | 26.4 | 16 |
| Syphilis (late/unknown) | 78.6 277 cases ▲ 77% | 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 Nueces County, chlamydia has fallen from 767.6 to 675.6 per 100,000 (12%), gonorrhea has fallen from 291.1 to 263.4 per 100,000 (10%), and P&S syphilis has fallen from 28.3 to 23.6 per 100,000 (17%).

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 Nueces County.
Local HIV snapshot
Nueces County HIV care continuum (2023)
Nueces County recorded 15.7 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Nueces County residents living with HIV, 84.4% 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 Nueces County tests for syphilis.

Data & references
Local context
Mustang Beach carries the unhurried rhythm that makes Port Aransas feel like a town built around the tides, short drives down TX 361, neighbors who've owned their places for years alongside renters cycling through the island's seasonal economy. That mix matters for sexual health: with nearly four in ten households renting at over a thousand dollars a month, cost and calendar pressures are real, and the people most likely to be navigating new relationships, young adults in their late teens and twenties, don't always have the flexibility to plan around clinic hours that assume a nine-to-five schedule. What the numbers here describe is a community that's largely settled (most adults are married, most households own their homes) but the renters and the younger crowd living alongside them face a different daily math.
When rent claims a meaningful chunk of a paycheck, a testing visit that's easy to reach and low-cost enough to feel routine is the one that actually gets scheduled, not deferred. If you're heading out anyway on a South Cut Off Road errand, pulling up the nearest listed option before you leave Mustang Beach is the simplest first step.
Getting there
Port Aransas scores 11.32/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
