DES MOINES, Iowa – The Iowa Department of Health and Human Services (Iowa HHS) was notified by the Illinois Department of Public Health that an Illinois resident with confirmed measles traveled to Iowa during their infectious period. Iowa HHS is notifying the public of potential exposure locations. As of March 5, a total of 1,281 confirmed measles cases have been reported in the United States in 2026. Of these, 1,191 (93)% were unvaccinated. In Iowa, nine measles cases were identified in 2025. To date, no measles cases have been identified among Iowa residents in 2026.

Measles is a highly contagious viral illness that is spread through the air when an infectious person coughs, sneezes, or breathes, and can stay in the air for up to two hours after a person with measles leaves the room. Iowa and Illinois health officials have identified a location visited by the individual while contagious, where the public might have been exposed to measles. Anyone who visited the following location within the listed timeframe should closely monitor for symptoms of measles (e.g., fever, cough, red/watery eyes, runny nose, and a rash). Anyone born in or after 1957 who visited the following locations and is unvaccinated or unsure of their immune status is at higher risk. 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 that you have been exposed to measles and have symptoms before arriving.

“With ongoing measles transmission in the United States, Iowans should make sure they’ve received a measles-containing vaccine and should consider an accelerated measles vaccination schedule for their children,” said Dr. Robert Kruse, State Medical Director.

While the routine measles-mumps-rubella (MMR) vaccine schedule is one dose at 12–15 months and a second dose at 4–6 years, Iowans should consider:

• An early extra dose of MMR between 6 and 11 months of age (“dose 0”); this dose does NOT count toward the routine series

• The first routine dose (dose 1) can be given after 12 months of age, at least 28 days after dose 0

• The second routine dose (dose 2) can be given at least 28 days after dose 1, instead of waiting until age 4–6 years

This page is updated weekly, on Fridays, with current case counts and public health guidance.  Iowa HHS will issue a press release when there is a confirmed public exposure that may pose a risk to others. When possible, individuals identified as close contacts will also be notified directly by public health officials.
