STD stats & rates
How reported STI rates in Union County, the county that includes North Sioux City, compare with South Dakota 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.
#50 of 66 South Dakota counties for chlamydia, a higher rate than 24% of the state
| Infection | Union County | South Dakota | United States |
|---|---|---|---|
| Chlamydia | 145.5 25 cases ▼ 73% | 531.6 | 492.2 |
| Gonorrhea | 5.8 1 cases ▼ 98% | 253.3 | 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 Union County, chlamydia has fallen from 255.8 to 145.5 per 100,000 (43%), gonorrhea has fallen from 53.5 to 5.8 per 100,000 (89%), and P&S syphilis has fallen from 17.6 to 5.8 per 100,000 (67%).

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 Union County.
Local HIV snapshot
Union County HIV care continuum (2023)
Union County recorded 0 new HIV diagnoses per 100,000 (2023), against 6.8 statewide and 13.7 nationally. 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 Union County tests for syphilis.

Data & references
Local context
The work here centers on construction, manufacturing, and the trades. Jobs that demand physical presence and long hours, which means health checkups often slip to the back of the calendar. For young adults in North Sioux City who are building careers or managing households near McCook Lake and Dakota Dunes, routine STI screening fits best when it doesn't interrupt the week. Testing in and around North Sioux City listed on this page includes clinics that accommodate working schedules, with results returned discreetly to your preferred contact method. A steady paycheck and stable housing define much of the community's character, yet confidentiality remains central to how people approach sexual health decisions.
The clinics available here understand that discretion isn't about shame: it's about keeping your medical record separate from your workplace, your family's assumptions, and your social circle. Screening happens on your terms, with no automatic flag or notification sent anywhere you haven't explicitly authorized. Proximity to Riverside Park and the river itself gives North Sioux City a connected feel, but that same closeness means privacy matters differently than it might in a larger place. Testing facilities in the area are set up to handle that reality: staff keep information compartmentalized, results are yours alone to share or keep, and the process is straightforward enough that a lunchtime visit or after-work appointment doesn't derail your day.
Getting there
At 7.13/20 on the EPA walkability index, day-to-day errands in North Sioux City 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 South Dakota 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 South Dakota, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Expedited Partner Therapy (EPT) is potentially allowable in South Dakota: it is not expressly authorized, but not prohibited either. Ask your provider whether they will prescribe treatment for a partner without a separate visit.
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.
