Measles cases in the U.S. reach a three-decade high, alarming York County families. YORK COUNTY, Pa. — Measles cases in the U.S. are rising. The cases are at the highest reported levels in three decades, and families in York County are concerned about the current outbreak.

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.

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.

More people have contracted measles in the US so far this year than in any year in the last three decades. New data from Atlanta-based Centers for Disease Control and Prevention shows 1,288 infections this year through 38 states,

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

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.

Los Angeles, Orange, Riverside and San Bernardino counties have reported eight cases so far this year compared to 10 total in 2024.
