Measles outbreak spreads across US

The outbreak has prompted urgent calls for vaccination as cases have more than doubled compared to the same period last year.

Dozens of people have been hospitalized, and officials in California and Manitoba have also reported significant jumps in infections.

The resurgence of the virus has become a political flashpoint, with lawmakers questioning Health Secretary RFK Jr. over his department's vaccine policies.

Medical experts warn that the erosion of public trust in health institutions is a major driver of the crisis.
