Measles cases have reached the highest point since 1992, with nearly 1,700 cases reported through mid-week, according to the latest data from the CDC.

Through Tuesday, there have been 44 outbreaks reported this year, and the large majority of cases have been associated with these outbreaks. That’s up from 16 outbreaks the previous year.

Here’s what you need to know:

  • About 92 percent of cases are from people who are unvaccinated or have unknown vaccination status.
  • The vaccination rate for kindergarten-age children was 92.7 percent for the 2023–2024 school year. That’s down from 95 percent a few years prior.
