STD stats & rates
How reported STI rates in Pima County, the county that includes Rillito, compare with Arizona and U.S. averages, based on the most recent 2023 surveillance data.
#5 of 15 Arizona counties for chlamydia, a higher rate than 67% of the state
| Infection | Pima County | Arizona | United States |
|---|---|---|---|
| Chlamydia | 555 5,901 cases ≈ the state average | 552.5 | 492.2 |
| Gonorrhea | 172 1,829 cases ▼ 10% | 190.7 | 179.5 |
| Syphilis (P&S) | 26.1 278 cases ▲ 8% | 24.1 | 15.8 |
| Syphilis (early) | 26.3 280 cases ▲ 7% | 24.6 | 16 |
| Syphilis (late/unknown) | 43.5 463 cases ▼ 21% | 55.3 | 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 Pima County, chlamydia has risen from 506.5 to 555 per 100,000 (10%), gonorrhea has fallen from 184.1 to 172 per 100,000 (7%), and P&S syphilis has risen from 15.5 to 26.1 per 100,000 (68%).
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 Pima County.
Local HIV snapshot
Pima County HIV care continuum (2023)
Pima County recorded 14.9 new HIV diagnoses per 100,000 (2023), against 14.6 statewide and 13.7 nationally. Among Pima County residents living with HIV, 75.7% are in care · 70.4% 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 Pima County tests for syphilis.

Data & references
Local context
Rillito's economy runs on ranching, equestrian work, and the trades that keep both going. Farrier shops, feed suppliers, equipment repair. That kind of work means physical demands, long hours outdoors, and schedules that don't always sync with clinic hours. Routine STI screening fits into the same category as a vehicle inspection or a horse's annual checkup: something you plan for, something that protects what matters, something best not delayed.
Young adults in Rillito, late teens through their thirties, make up a significant part of the population, and that's precisely when confidential screening becomes practical rather than theoretical. Testing in and around Rillito, listed on this page, accommodates both the person with a predictable schedule and the person whose day changes by the hour. Whether you're based near Marana or closer to Rillito Vista Park, clinics here understand that life happens at the pace of the work you do. Confidentiality in a town where people recognize faces is straightforward: your test results belong to you, your provider, and no one else.
That clarity matters when you're deciding whether to get tested at all. The testing sites available locally handle that contract seriously, not as a legal formality, but as the foundation of care that actually reaches people.
Getting there
At 5.53/20 on the EPA walkability index, day-to-day errands in Rillito 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 Arizona 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 Arizona, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Arizona 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.
