At least 124 cases of measles have been identified in Texas since late January, mostly among children and teenagers who are either unvaccinated or whose vaccination status is unknown, officials say.
Arizona is similarly at risk for measles because the state has several pockets of extremely low vaccination rates, including in Yavapai and Mohave counties, according to school vaccination data from the Arizona Department of Health Services for the 2023-24 school year. Data for the current school year is not yet publicly available.
