US measles cases more than double last year as outbreaks spread across 43 areas
US health authorities reported 178 additional measles cases this week, bringing the 2026 total to 4,588, already more than twice the 2025 count. Pennsylvania has recorded 1,338 cases, while South Carolina and Utah each report more than 500. The article says official totals may undercount infections and notes uncertainty around a reported death. It also examines changes to vaccine-injury reporting and criticism of Health Secretary Robert F Kennedy Jr’s influence over federal vaccine policy.
