With measles confirmed in nearly half of U.S. states, here's the outlook in Minn.

The number of measles cases in the United States is at a 25-year high, with confirmed reports of the illness in 23 states already this year. So far, Minnesota is not among them.

MPR News host Cathy Wurzer checked in with Kris Ehresmann for the measles outlook in Minnesota this year, and what people can do to ensure they're protected. Ehresmann is director of the infectious disease division at the Minnesota Department of Health.
