Jefferson county coroner says 40-year-old woman died on Saturday, while two infants died with disease in August

A coroner in Pennsylvania announced the death of a 40-year-old woman associated with the state’s ongoing measles outbreak. The death appears to mark the third in the US state’s ongoing outbreak.

Two previous deaths in the state were in infant children. In one case, the infant was born with a genetic defect that made her vulnerable to infection. The second infant child was infected with measles, and died of a ruptured spleen.

The woman died on Saturday, according to reporting by WTAE in Pittsburgh.

“Many people associate measles with a childhood illness, but it can lead to severe complications in individuals of any age,” Jason Stiver, the Jefferson county chief deputy coroner and public relations officer, told WTAE.
