Iowa Confirms First Measles Case Since 2019

DES MOINES, Iowa — Iowa health officials confirmed the state’s first case of measles since 2019. This case, reported on May 23, 2025, involves an unvaccinated adult in central Iowa, according to the Department of Health and Human Services (HHS).

Health officials stated that more than 1,000 measles cases have been reported across the United States this year, resulting in three deaths. The Iowa case has raised concerns due to recent outbreaks nationwide, with Iowa being the 31st state to report such an infection this year.

Dr. Joel Waddell of Blake Children’s Hospital indicated he anticipated this case might eventually occur. He noted the extremely contagious nature of measles, which can lead to quick transmission, especially with the upcoming Memorial Day weekend travel.

While state officials do not expect widespread public exposure from this case, they have begun contacting individuals who may have been in close contact with the infected person. Dr. Robert Kruse, Iowa’s State Medical Director, emphasized the importance of vaccination, stating, “The best tool we have is getting the measles, mumps, and rubella (MMR) vaccine.”

Currently, vaccination rates for 2-year-olds in Iowa stand at about 84%, well below the 95% threshold needed to maintain herd immunity and prevent outbreaks. Dr. Waddell warned that low vaccination rates could lead to further infections if the virus spreads.

Symptoms of measles include fever, cough, red or watery eyes, a runny nose, and a characteristic rash. Health officials recommend that anyone who suspects they or their child may have measles contact their healthcare provider and inform them prior to arrival to avoid exposing others.

In light of this case, Iowa health authorities are urging residents to check their vaccination records and ensure they are adequately protected against measles.
