Pennsylvania asks for CDC measles help amid Kennedy dispute

Key Points:

• Pennsylvania's health department has requested emergency support from the US CDC to address one of the country's largest measles outbreaks, but only if the CDC recognizes four measles-associated deaths reported by the state, highlighting tensions with the Trump administration.
• The dispute centers on US Health Secretary Robert F. Kennedy Jr., who has questioned whether the reported deaths were caused by measles and has instructed the CDC not to include Pennsylvania's fatalities in national counts, a move criticized by disease experts as unusual political interference.
• Pennsylvania Governor Josh Shapiro and the state health department have resisted earlier CDC assistance offers, arguing they had the outbreak under control, but the outbreak has since grown to over 700 cases across 37 counties with four deaths.
• The outbreak is part of the worst US measles resurgence in over three decades, driven by rising vaccine hesitancy, and has led to a slowdown in measles vaccination rates in Pennsylvania despite public health efforts.
• The CDC maintains it will not condition critical public health assistance on political demands, while experts note that misalignment between state and federal leaders on outbreak severity complicates response efforts.
