CommuniCare Health Centers - New Braunfels carries federal qualification as a community health center, which ties STI screening fees directly to each patient's income.

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 Santa Clara, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% 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 |
| Syphilis (late/unknown) | 22.8 43 cases ▼ 49% | 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 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
Santa Clara's economy turns on manufacturing and light industrial work, shifts that demand physical exams and regular health checkups as a condition of employment. That routine screening culture extends naturally to STI testing, which many residents approach with the same straightforward attitude they bring to other preventive care. Young adults moving through Santa Clara for work or school often find themselves in need of testing before starting a job or after a change in circumstances, and clinics in and around Santa Clara listed on this page offer the kind of quick, discreet appointments that fit into a working schedule. What sets testing here apart is the expectation of privacy without fanfare.
Most people know someone at work or at Bulldog Football Park, so the ability to walk into a clinic, get screened, and leave without running into half the town matters. Providers understand this reality and structure their operations accordingly: results stay confidential, intake is streamlined, and follow-up happens through secure channels rather than a phone call to your home. Getting tested is treated as ordinary maintenance, not confession. That frame takes the weight out of the decision and makes it easier for residents to catch infections early or confirm their status before moving forward with partners.
Getting there
At 4.26/20 on the EPA walkability index, day-to-day errands in Santa Clara 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.
