STD stats & rates
How reported STI rates in Tom Green County, the county that includes Christoval, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~35% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#18 of 254 Texas counties for chlamydia, a higher rate than 93% of the state
| Infection | Tom Green County | Texas | United States |
|---|---|---|---|
| Chlamydia | 610.6 727 cases ▲ 24% | 491.9 | 492.2 |
| Gonorrhea | 207.5 247 cases ▲ 18% | 176.4 | 179.5 |
| Syphilis (P&S) | 24.4 29 cases ▲ 63% | 15 | 15.8 |
| Syphilis (early) | 43.7 52 cases ▲ 66% | 26.4 | 16 |
| Syphilis (late/unknown) | 69.7 83 cases ▲ 57% | 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 Tom Green County, chlamydia has risen from 562.5 to 610.6 per 100,000 (9%), gonorrhea has fallen from 250 to 207.5 per 100,000 (17%), and P&S syphilis has risen from 20.8 to 24.4 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 Tom Green County.
Local HIV snapshot
Tom Green County HIV care continuum (2023)
Tom Green County recorded 31.3 new HIV diagnoses per 100,000 (2023), against 20.2 statewide and 13.7 nationally. Among Tom Green County residents living with HIV, 82.5% are in care · 71.4% 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 Tom Green County tests for syphilis.

Data & references
Local context
Allen Hill sits at the quiet edge of a community where nearly every household owns its land outright and most adults are married, a settled, rooted place by almost any measure. Half the working-age population isn't in the labor force at all, which sounds like leisure but more often means caregiving, retirement, or seasonal rhythms that leave little margin for weekday appointments. That stability shapes who gets overlooked. Young adults in their late teens and twenties live here too, and for them the practical calculus of getting tested is almost entirely about distance and schedule.
When the nearest site is a real drive out toward San Angelo or beyond, the barrier isn't hesitation; it's logistics compounded by days when the truck is needed elsewhere or someone else has the keys. The options listed here vary enough in hours, cost structure, and distance that the right fit depends on which day a vehicle is free and whether a fee-sliding clinic fits the household budget better than a flat-rate one. For someone heading out along the highway past Brushy Knob, knowing which option to call ahead for, and which takes walk-ins, is the difference that actually matters.
Getting there
At 6.17/20 on the EPA walkability index, day-to-day errands in Christoval generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
