Measles cases in the United States have more than doubled since last year

According to the Centers for Disease Control and Prevention, measles cases across the United States have surged to over double the previous year's total. The majority of those infected have either not received the vaccine or lack documented vaccination records. Pennsylvania leads the outbreak, reporting the highest number of cases and several deaths, including victims from communities with strong Amish presence.

Health officials are urging increased vaccination, especially for infants who are too young to be immunized. Pediatric specialist Deborah Greenhouse has emphasized the collective responsibility to protect vulnerable children.
