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.

Congenital syphilis is the fastest-rising STI: what to test, and when

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 Hardin County tests for syphilis.

Local context

About Union, IA

Union sits quietly along the edges of Daisy Long Memorial Park and Lepeley County Park, a town where the majority of residents own their homes and a good share of households are headed by married couples. The kind of settled, rooted character that shapes daily rhythms in ways that matter when you're thinking about healthcare access. Beneath that stability, the logistics of getting tested here take some planning. Young adults in their late teens and twenties, the years when STI exposure tends to peak, are already the group most likely to delay screening when getting there requires coordination rather than convenience.

In a place where a car trip to another county is the baseline, that delay can stretch longer than it should. For the roughly one-in-four households here that rent at Union's modest going rate, cost-sensitive options among those listed on this page carry real weight. Sliding-scale fees or no-cost testing can be the deciding factor for a working renter whose monthly budget leaves little cushion, and that's the specific resident for whom knowing which clinic charges what, before arriving, matters most.

Confidentiality & consent in Iowa

Minor consent and partner treatment (EPT) under state law, plus how to test privately

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).

Can a minor consent on their own?

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.

Can my partner be treated too? (EPT)

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.
