Health officials say 71 more cases were reported last week, with 68 of them from New York. That brings this years total to 626.
That is already the most since 2014, when 667 were reported for the whole year. The most before that was 963 cases in 1994.
Twenty-two states have reported cases, but the vast majority have been in New York — mainly in New York City and in nearby Rockland County. Most of the New York cases have been unvaccinated people in Orthodox Jewish communities.
The Centers for Disease Control and Prevention released the latest numbers Monday.
