STD stats & rates
How reported STI rates in Taos County, the county that includes Costilla, compare with New Mexico and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~18% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#25 of 33 New Mexico counties for chlamydia, a higher rate than 24% of the state
| Infection | Taos County | New Mexico | United States |
|---|---|---|---|
| Chlamydia | 270.3 93 cases ▼ 48% | 523.6 | 492.2 |
| Gonorrhea | 81.4 28 cases ▼ 52% | 169 | 179.5 |

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 Taos County, chlamydia has risen from 255.2 to 270.3 per 100,000 (6%), gonorrhea has risen from 78.3 to 81.4 per 100,000 (4%), and P&S syphilis has risen from 8.7 to 11.6 per 100,000 (33%).

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 Taos County.
Local HIV snapshot
Taos County HIV care continuum (2023)
Taos County recorded 0 new HIV diagnoses per 100,000 (2023), against 10.4 statewide and 13.7 nationally. Among Taos County residents living with HIV, 72% are in care · 70% 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 Taos County tests for syphilis.

Data & references
Local context
San Pedro Mesa's quiet ridge defines Costilla's edges as clearly as NM 522 cuts through the heart of town, and the people who call this place home do so as owners, not renters, often for decades at a stretch. That kind of deep-rooted stability shapes daily life in ways that can make a drive to a clinic feel less urgent than the next fence line or irrigation ditch. Yet younger adults in their late teens and twenties, even in a small, settled community, are forming relationships and navigating health decisions that don't pause for geography.
The single option listed on this page reflects just how thin the local healthcare infrastructure is in this stretch of Taos County, and cost pressure doesn't announce itself loudly here, but a community where no households report top-bracket earnings is one where out-of-pocket expenses for any health visit carry real weight. That distance isn't just inconvenient: it's the concrete reason why knowing exactly which option is listed here, what it costs, and when it's open matters before anyone gets behind the wheel on NM 522.
Getting there
At 4.58/20 on the EPA walkability index, day-to-day errands in Costilla 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 New Mexico 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 New Mexico, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
New Mexico 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.
