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.

Most of the cases come from the 27 reported outbreaks in 2025.

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.

Fox News senior medical analyst Dr. Marc Siegel weighs in on childhood obesity concerns and the surge in measles cases across the U.S. on 'America's Newsroom.'

Measles was considered eradicated in the United States in 2000. For the first time in 25 years, cases have reached a new high.

Measles cases in the U.S. have hit a three-decade high, reaching the highest yearly total since 1992 in less than seven months, according to data released Wednesday by the Centers for Disease Control and Prevention.

The Centers for Disease Control and Prevention says the U.S. is currently experiencing its worst measles outbreak in more than 30 years, according to the Associated Press. On Wednesday, the CDC said the 2025 case count has surpassed the 2019 count, when there were 1,274 cases for the year.
