STD stats & rates
How reported STI rates in Cass County, the county that includes Union, compare with Nebraska and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~34% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#21 of 93 Nebraska counties for chlamydia, a higher rate than 77% of the state
| Infection | Cass County | Nebraska | United States |
|---|---|---|---|
| Chlamydia | 251.4 69 cases ▼ 46% | 468.8 | 492.2 |
| Gonorrhea | 29.1 8 cases ▼ 75% | 115.5 | 179.5 |
| Syphilis (P&S) | 7.3 2 cases ▼ 30% | 10.4 | 15.8 |

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 Cass County, chlamydia has risen from 184.2 to 251.4 per 100,000 (36%), gonorrhea has fallen from 71.4 to 29.1 per 100,000 (59%), and P&S syphilis has fallen from 7.4 to 7.3 per 100,000 (1%).

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 Cass County.
Local HIV snapshot
Cass County HIV care continuum (2020)
Cass County recorded 0 new HIV diagnoses per 100,000 (2020), against 6 statewide and 13.7 nationally. Among Cass County residents living with HIV, 33.3% are in care · 33.3% 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 Cass County tests for syphilis.

Data & references
Local context
Union sits close to the bluffs where US 34 meets Highway 75, and the people who call it home are overwhelmingly long-term owners, not a renter in sight, which says something real about the stability of life here. Most households are married couples, and with more than four in ten working-age adults outside the labor force, caregiving, retirement, and part-time arrangements shape daily schedules as much as a standard nine-to-five does. For younger adults still forming relationships, the crowd statistically most likely to benefit from routine STI screening, that mix of rural quiet and limited weekday flexibility makes the question of when and where to get tested genuinely practical rather than abstract.
That breadth (spanning varied hours, fee structures, and service types) is what makes follow-through realistic for Union households. Whether someone heads east toward Plattsmouth or north along Highway 75, having that many options in and around Union means one scheduling hiccup doesn't become a reason to let another month pass.
Getting there
At 4.91/20 on the EPA walkability index, day-to-day errands in Union 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 Nebraska 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 Nebraska, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Nebraska 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.
