STD stats & rates
How reported STI rates in Sioux County, the county that includes Matlock, compare with Iowa and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#73 of 99 Iowa counties for chlamydia, a higher rate than 26% of the state
| Infection | Sioux County | Iowa | United States |
|---|---|---|---|
| Chlamydia | 182.1 66 cases ▼ 57% | 426.8 | 492.2 |
| Gonorrhea | 13.8 5 cases ▼ 88% | 116.8 | 179.5 |
| Syphilis (P&S) | — no data | 10.3 | 15.8 |
| Syphilis (early) | — no data | 9.2 | 16 |
| Syphilis (late/unknown) | — no data | 9.9 | 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 Sioux County, chlamydia has fallen from 186.8 to 182.1 per 100,000 (3%), gonorrhea has fallen from 19.5 to 13.8 per 100,000 (29%), and P&S syphilis has fallen from 8.4 to 2.8 per 100,000 (67%).
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 Sioux County.
Local HIV snapshot
Sioux County HIV care continuum (2023)
Sioux County recorded 0 new HIV diagnoses per 100,000 (2023), against 5.1 statewide and 13.7 nationally. Among Sioux County residents living with HIV, 83.3% are in care · 75% 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 Sioux County tests for syphilis.

Local resources & officials
Data & references
Local context
Matlock runs at a working pace, the kind of town where most households own their home outright and a solid share of adults are in the workforce on any given weekday. That settled, ownership-heavy character shapes daily rhythms in ways that matter for health care: schedules are built around jobs and families, not around appointments, and a clinic visit has to earn its place in the week. With nearly three-quarters of adults married and average households running close to three people, care decisions are often made with others in mind, which can make routine screening feel like one more thing to coordinate rather than something a person simply handles for themselves.
Sioux County's STI landscape is what it is across rural stretches, and Matlock's younger adults, people in their late teens and twenties forming relationships and navigating new situations, are the group for whom timely, uncomplicated access to testing matters most. Cost tends not to be the sharpest barrier here, given the proportion of households with solid earnings, but convenience is a different story. There is no walking over on a lunch break; options listed on this page require a deliberate drive out of town, which means the easier those options are to book in advance, the more likely the trip actually happens.
Getting there
At 7.44/20 on the EPA walkability index, day-to-day errands in Matlock 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 Iowa 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 Iowa, a minor of any age can consent to confidential STI testing and treatment on their own; a parent may be notified only in the case of a positive HIV test result.
Iowa 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.
