Measles cases and deaths in the United States, OWID.
The U.S. Centers for Disease Control and Prevention (CDC) confirmed four measles-associated deaths this year, but state health departments have reported higher numbers, including two new deaths in Pennsylvania and Wisconsin.
In Pennsylvania, an unvaccinated resident of Montour County who tested positive for measles had died, marking the seventh measles-associated death in the state this year.
Wisconsin reported the death of a child, the second measles-associated death in the state this year, and the first since 1990.
Nationwide, 75% of counties and jurisdictions with measles vaccine data fall below the 95% vaccination rate needed to prevent outbreaks, according to an NBC News investigation.
As of Thursday, Wisconsin reported 431 cases of measles, all but three in unvaccinated people, and Pennsylvania has reported 1,542 measles cases across 46 counties this year.
The CDC reported 5,182 measles cases in the U.S. This year across 47 states and jurisdictions, with New York also reporting one death.
The coroner listed the cause of death as measles in both Pennsylvania and Wisconsin, state health officials said.
The state’s explosive, ongoing measles outbreak has led to 1,467 cases so far this year in Wisconsin.
Experts will determine next week if the U.S. has lost its measles elimination status.
The CDC defines a measles-associated death as one where the person dies within 30 days of testing positive and shows clinical signs of infection, with no other significant cause for the death.
