The Philadelphia Department of Public Health confirmed that newborns at Children's Hospital of Philadelphia may have been exposed to measles on September 11. Infants currently in the neonatal intensive care unit are receiving preventive antibody treatment.
Why it matters
Measles is a highly contagious airborne virus that can persist in rooms for up to two hours after an infected person has left. Because infants under 12 months are not yet eligible for the MMR vaccine, they remain highly vulnerable to infection.
Pennsylvania has recorded 731 measles cases and 141 hospitalizations throughout 2026, with 4 deaths reported. Fewer than 1% of these state cases occurred among fully vaccinated individuals.
