STD stats & rates
How reported STI rates in Hemphill County, the county that includes Canadian, compare with Texas and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~26% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#219 of 254 Texas counties for chlamydia, a higher rate than 14% of the state
| Infection | Hemphill County | Texas | United States |
|---|---|---|---|
| Chlamydia | 156.8 5 cases ▼ 68% | 491.9 | 492.2 |
| Gonorrhea | 31.4 1 cases ▼ 82% | 176.4 | 179.5 |
| Syphilis (P&S) | — no data | 15 | 15.8 |
| Syphilis (early) | — no data | 26.4 | 16 |
| Syphilis (late/unknown) | — no data | 44.3 | 29.5 |
Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Hemphill County, chlamydia has risen from 88.7 to 156.8 per 100,000 (77%), and gonorrhea has risen from 30.6 to 31.4 per 100,000 (3%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Hemphill County.
Local HIV snapshot
Hemphill County HIV care continuum (2022)
Hemphill County recorded 0 new HIV diagnoses per 100,000 (2022), against 20.2 statewide and 13.7 nationally. Among Hemphill County residents living with HIV, 80% are in care · 60% 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 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 Hemphill County tests for syphilis.

Local resources & officials
Data & references
Local context
The neighborhood around Mary B. Isaacs carries the easy rhythm of a town where most families have put down roots: nearly seven in ten households own their homes here, and the average household runs close to four people. That kind of stability shapes how Canadian feels day to day: busy households, working schedules, and a social fabric where everyone more or less knows everyone else. For the roughly three in ten residents who rent, monthly costs stay modest by most standards, but a household budget stretched across several people leaves little room for appointments that feel optional or inconvenient. That's where the geography becomes the real consideration.
Options listed on this page require a deliberate trip, not a lunchtime detour. For young adults in their twenties who are still building routines and navigating relationships, that kind of distance can quietly convert a clear intention into an indefinitely postponed errand. A significant share of Canadian's workforce is active and employed, meaning evenings and weekends are the windows that actually open. Checking hours and telehealth pre-screening for the options listed here before driving out on US 83 is the one move that turns the trip from unpredictable to done.
Getting there
At 6.8/20 on the EPA walkability index, day-to-day errands in Canadian 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.
