The CDC has updated its travel advisory due to a surge in measles cases, urging international travelers to get vaccinated. With over 1,000 confirmed measles cases in the US in 2025, 96% are unvaccinated or of unknown vaccination status. The virus spreads easily, prompting the CDC to recommend vaccination before international travel or consultation with a medical professional. Recent outbreaks at locations like Denver International Airport highlight the risk.
