North Dakota is the 11th state in the U.S. with a measles outbreak, logging its first cases since 2011.

There have been 935 confirmed cases of measles across nearly 30 states so far this year, according to the latest update from the CDC on Friday, an increase of 51 over the last week and far surpassing the 285 measles cases reported in the entirety of 2024 (the CDC does not provide data on how many cases are actively infectious).

A measles alert sign hangs outside the entrance to the Cohen Children's Medical Center, where the state health department confirmed that a baby tested positive and that there is a possibility of exposure to others at the facility,
