U.S. records most measles cases in single year since record 2019 wave

The U.S. has seen at least 308 measles cases so far this year, according to figures published Friday by the Centers for Disease Control and Prevention, marking the most infections reported nationwide in a single year since a record 2019 wave.

More than 90% of the cases have been from a growing outbreak in Texas and neighboring New Mexico – totaling at least 284 measles infections in the CDC's data.

Two additional "probable" cases linked to the outbreak this week in Oklahoma have so far not been added to the CDC's tally.
