Spanish is a working language at Legacy Community Health in Pasadena, with interpretation services extending to additional languages, so a patient's preferred language shapes the clinical conversation directly, including counseling on medication adherence and prevention options.

Harris Health System in Pasadena covers the full bacterial and viral panel (gonorrhea, chlamydia, syphilis, hepatitis A, B, and C, herpes, and HIV) treating bacterial infections the same visit and pricing everything on a sliding scale. Appointments are required. Care is delivered in Spanish.
Harris Health System delivers care in Spanish as a direct operational capacity: counseling, medication adherence education, and treatment discussions happen in the language without a relay. For patients managing ongoing regimens like PrEP or HIV treatment, that directness shapes whether instructions actually stick.
Many STI clinics test and treat but stop short of prescribing the medications that reduce future transmission risk. Harris Health System in Pasadena prescribes both PrEP and PEP, and carries a dedicated PrEP program for uninsured patients. Closing the gap between a diagnosis and a prevention plan.
Harris Health System treats hepatitis C on-site, not just confirms it. That means a patient who tests reactive doesn't leave with paperwork and a separate appointment to find, the treatment relationship begins at the same clinic where the diagnosis was made.

For someone whose primary language is Spanish, that means discussing symptoms, understanding results, and following a treatment plan without a gap in comprehension.
Baylor College of Medicine tests for herpes in addition to gonorrhea, syphilis, chlamydia, and HIV, which matters most for anyone who wants a complete picture or has specific reason to screen beyond the bacterial four. Getting that answer in one appointment, rather than sourcing it separately, is what the broader panel makes possible.

STD stats & rates
How reported STI rates in Harris County, the county that includes South Houston, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~31% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#13 of 254 Texas counties for chlamydia, a higher rate than 95% of the state
| Infection | Harris County | Texas | United States |
|---|---|---|---|
| Chlamydia | 641.4 31,014 cases ▲ 30% | 491.9 | 492.2 |
| Gonorrhea | 240.6 11,631 cases ▲ 36% | 176.4 | 179.5 |
| Syphilis (P&S) | 28.2 1,363 cases ▲ 88% | 15 | 15.8 |
| Syphilis (early) | 40.8 1,975 cases ▲ 55% | 26.4 | 16 |
| Syphilis (late/unknown) | 57 2,756 cases ▲ 29% | 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 Harris County, chlamydia has risen from 528.4 to 641.4 per 100,000 (21%), gonorrhea has risen from 239.6 to 240.6 per 100,000 (0%), and P&S syphilis has risen from 13.3 to 28.2 per 100,000 (112%).

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 Harris County.
Local HIV snapshot
Federal priority area: Harris County is one of 48 U.S. counties prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Harris County HIV care continuum (2023)
Harris County recorded 33.4 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Harris County residents living with HIV, 86.7% know their status · 75.2% are in care · 65.1% 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 Harris County tests for syphilis.

Local resources & officials
Data & references
Local context
Spencer Highway cuts through a South Houston where home values run well below the regional norm and typical rents stay modest enough that most households are managing on careful budgets. That cost-of-living reality shapes daily decisions, including health ones: with fewer than one in seven households earning six figures and unemployment running meaningfully above Texas's statewide average, an out-of-pocket clinic visit can feel like a line item worth postponing. The household profile here adds another layer. Average households are large, closer to four people than three, and nearly half of adults are married, meaning sexual health decisions ripple across partners and families rather than sitting with one person alone.
Young adults, people in their late teens and twenties, make up a substantial share of those households and represent the years when STI transmission runs highest, often because testing simply hasn't become a habit yet. Getting to a clinic from neighborhoods like Edgebrook or East Haven means a car trip along Spencer Highway or TX 3, and with nearly two in five residents not in the labor force, coordinating that trip around someone else's work or childcare schedule is a real constraint. Knowing which listed site offers the earliest appointment on a given weekday is the practical starting point.
Getting there
South Houston scores 10.58/20 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.

These are the federal Medicare reference prices for processing each lab test. Public clinics and the community health centers serving South Houston often test free or on a sliding scale; private labs and at-home kits bundle several tests into one fee.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
