The U.S. has 1,001 measles cases and 11 states with active outbreaks

As the outbreak in West Texas slows, other states are reporting multiple cases.

The U.S. surpassed 1,000 measles cases Friday, even as Texas posted one of its lowest counts of newly confirmed cases since its large outbreak began three months ago.

Texas still accounts for the vast majority of cases in the U.S., with 709 confirmed as of Friday in an outbreak that also spread measles to New Mexico, Oklahoma and Kansas. Two unvaccinated elementary school-aged children died from measles-related illnesses in the epicenter in West Texas, and an adult in New Mexico who was not vaccinated died of a measles-related illness.

Other states with active outbreaks — which the CDC defines as three or more related cases — include Indiana, Michigan, Montana, Ohio, Pennsylvania and Tennessee.
