STD stats & rates
How reported STI rates in Webb County, the county that includes Los Arcos, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~37% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#49 of 254 Texas counties for chlamydia, a higher rate than 81% of the state
| Infection | Webb County | Texas | United States |
|---|---|---|---|
| Chlamydia | 474.1 1,276 cases ▼ 4% | 491.9 | 492.2 |
| Gonorrhea | 87.3 235 cases ▼ 51% | 176.4 | 179.5 |
| Syphilis (P&S) | 16.7 45 cases ▲ 11% | 15 | 15.8 |
| Syphilis (early) | 20.8 56 cases ▼ 21% | 26.4 | 16 |
| Syphilis (late/unknown) | 55 148 cases ▲ 24% | 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 Webb County, chlamydia has risen from 387.1 to 474.1 per 100,000 (22%), gonorrhea has risen from 52.4 to 87.3 per 100,000 (67%), and P&S syphilis has risen from 2.6 to 16.7 per 100,000 (542%).

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 Webb County.
Local HIV snapshot
Webb County HIV care continuum (2023)
Webb County recorded 17.1 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Webb County residents living with HIV, 59.2% are in care · 52.5% 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 Webb County tests for syphilis.

Data & references
Local context
Lloyd Bentsen Highway cuts through Los Arcos with the unhurried pace of a town where most households have put down roots: ownership rates here run well above national norms, and the community has a settled, multigenerational character. But that stability coexists with economic conditions that shape daily decisions in real ways: with no households in the six-figure income range and unemployment running extraordinarily high, discretionary spending on healthcare tends to get weighed carefully against everything else. Those pressures land hardest on younger adults in their late teens and twenties, who make up a substantial slice of Los Arcos residents. In Webb County, STI rates reflect what national surveillance consistently finds for this life stage: frequent relationship transitions, lower rates of routine care, and less accumulated experience navigating the healthcare system.
For residents whose income leaves little cushion, the cost column on the clinic cards matters more than almost anything else. Sliding-scale fees or no-cost visits aren't a convenience, they're often the condition under which a test happens at all. Someone stretching a fixed or sporadic paycheck in Los Arcos will read that fee line first.
Getting there
At 7.87/20 on the EPA walkability index, day-to-day errands in Los Arcos 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.
