CommuniCare Health Centers in San Marcos runs on sliding-scale fees with Medicaid, Medicare, and private insurance accepted, covering a panel that spans HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, and TB. Appointments required.
CommuniCare employs Spanish-speaking staff directly and maintains interpretation services for other languages, meaning clinical conversations (symptom history, test results, treatment instructions) happen in real time without a relay. That staffing choice keeps medical detail intact from provider to patient.
CommuniCare tests for herpes and hepatitis A, B, and C in addition to HIV, syphilis, gonorrhea, and chlamydia, which means infections that often go undetected without explicit testing are caught in the same appointment rather than requiring a separate visit elsewhere.

CentroMed in New Braunfels requires an appointment, so visits run on a schedule that keeps wait times predictable, and a single one covers gonorrhea, chlamydia, syphilis, HIV, hepatitis, and TB, with same-visit treatment for bacterial infections and sliding-scale fees for everyone. Spanish-language care is built into the practice.
CentroMed staffs clinicians who conduct the full visit in Spanish (history, counseling, and treatment instructions) so nothing passes through a secondary layer. Dosing instructions, follow-up timelines, and prevention education are communicated directly, in the same language the clinical reasoning happens in.
CentroMed's panel is built to test for hepatitis A, B, and C alongside the standard bacterial and viral infections, and the clinic carries hepatitis A and B vaccines on-site to close any gaps identified. That means a single appointment can both detect and begin to address hepatitis exposure, not just flag it.

STD stats & rates
How reported STI rates in Guadalupe County, the county that includes Seguin, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~29% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#145 of 254 Texas counties for chlamydia, a higher rate than 43% of the state
| Infection | Guadalupe County | Texas | United States |
|---|---|---|---|
| Chlamydia | 270.1 509 cases ▼ 45% | 491.9 | 492.2 |
| Gonorrhea | 102.9 194 cases ▼ 42% | 176.4 | 179.5 |
| Syphilis (P&S) | 8.5 16 cases ▼ 43% | 15 | 15.8 |
| Syphilis (early) | 16.4 31 cases ▼ 38% | 26.4 | 16 |

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 Guadalupe County, chlamydia has fallen from 326.6 to 270.1 per 100,000 (17%), gonorrhea has fallen from 116.4 to 102.9 per 100,000 (12%), and P&S syphilis has risen from 5.2 to 8.5 per 100,000 (63%).

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 Guadalupe County.
Local HIV snapshot
Guadalupe County HIV care continuum (2023)
Guadalupe County recorded 7 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Guadalupe County residents living with HIV, 76.3% are in care · 67.1% 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 Guadalupe County tests for syphilis.

Data & references
Local context
Sebastopol House anchors the older heart of Seguin, where front porches face quiet streets and households tend to run larger than the Texas average, often three or more people under one roof. That kind of density, multigenerational or shared, shapes how health decisions get made: a single car, a packed schedule, a rent payment that lands every month whether hours were full or not. With nearly two in five residents renting at rates that leave little cushion, and fewer than one in five households clearing six figures, the practical calculus around taking time off for a clinic visit is real. Young adults, people moving through their late teens and twenties, represent a meaningful slice of Seguin's population and the years when STI exposure runs highest, often before regular healthcare relationships are established.
Some of those options require heading out on US 90 or TX 123, so knowing which one fits your day before you leave matters. Manuel C. Castilla Park sits close enough to central Seguin that it orients the surrounding neighborhood toward everyday errands rather than long drives. Checking the nearest listed clinic's hours against your next routine trip down Kingsbury Street is the most direct move from here.
Getting there
At 7.32/20 on the EPA walkability index, day-to-day errands in Seguin generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
