The U.S. has recorded the most measles cases in a single year since a 2019 wave, Centers for Disease Control and Prevention data shows. The majority of the infections have been reported in an outbreak in West Texas that has led to the deaths of two children.
Of the more than 1,000 cases nationwide, this latest one is the sixth to have been identified in Colorado.
