With one-fifth of states seeing active measles outbreaks, the U.S. is nearing 900 cases, according to figures posted Friday by the U.S. Centers for Disease Control and Prevention.
The CDC’s confirmed measles cases count is 884, triple the amount seen in all of 2024. The vast majority — 646 — are in Texas, where an outbreak in the western part of the state that’s approaching the three-month mark.
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 — defined as three or more cases — include Indiana, Kansas, Michigan, Montana, New Mexico, Oklahoma, Ohio, Pennsylvania and Tennessee.
North America has two other ongoing outbreaks. One in Ontario, Canada, has resulted in 1,020 cases from mid-October through Wednesday. And as of Friday, the Mexican state of Chihuahua state had 605 measles cases, according to data from the state health ministry. The World Health Organization has said cases in Mexico are linked to the Texas outbreak.
