Iowa Health Officials Confirm First Measles Case in 2026 in Iowa Resident, Release Locations of Potential Measles Exposures

Des Moines, IA - The Iowa Department of Health and Human Services (Iowa HHS) has confirmed a case of measles in a vaccinated adult resident of central Iowa. Measles infection was acquired during international travel. This is the first measles case that has been identified in Iowa in 2026. Iowa reported a total of nine confirmed measles cases in 2025. Across the United States, a total of 2,289 confirmed measles cases were reported in 2025, resulting in 243 hospitalizations and three deaths. For 2026, as of July 2nd a total of 2,170 confirmed measles cases have been reported across the United States; 93% were unvaccinated or had unknown vaccination status. Individuals who were vaccinated and still get measles typically experience milder illness and are less likely to spread the virus to others.

Iowa HHS and local health officials have identified locations visited by the individual while contagious, where the public might have been exposed to measles. Anyone present at the following locations during the listed date and time should monitor for symptoms of measles for 21 days. Symptoms of measles include fever, cough, red/watery eyes, runny nose, and a rash. If you think you have been exposed to measles and have symptoms, call your medical provider or nearest emergency room ahead of time and tell them before arrival that you have been exposed to measles and have symptoms.

Measles is a highly contagious viral illness that is spread through the air when an infectious person coughs, sneezes, or breathes. "While this is the first case of measles in Iowa in 2026, this is a reminder that measles continues circulating throughout the United States and throughout the world," said Dr. Robert Kruse, State Medical Director. "The routine childhood immunization series is still our strongest protection against measles infection."

Throughout 2025, Iowans responded to the measles outbreak by seeking MMR vaccinations and more MMR doses were administered in 2025 in Iowa than the preceding two years. Getting vaccinated is the best way to protect yourself, your family, and your community. Given continued measles activity across the United States and the world, residents should confirm they are up to date on MMR vaccination and parents should talk to a clinician regarding accelerated MMR vaccination options for their children.
