The US Centers for Disease Control and Prevention on Wednesday tallied the highest number of US measles cases since the disease was declared eliminated a quarter-century ago, just as a key Senate committee split the vote to advance President Donald Trump’s nominee to lead the public health agency.

Cases are rising in the U.S., but the CDC says most people who bring measles into the U.S. are unvaccinated residents who traveled internationally.

According to the CDC, a total of 1,288 confirmed measles cases were reported by 39 states so far this year. That marks the highest annual measles case tally in 33 years, when officials recorded more than 2,100 infections in 1992.

The agency says the decision comes after a steady drop in cases and no new human infections reported since February. The emergency declaration, first issued on April 4, 2024, helped the CDC ramp up staffing and support for affected areas.
