The CDC is urging unvaccinated Americans to cancel flights due to a measles outbreak spreading on airplanes. The agency confirmed at least one case of in-flight transmission after investigating dozens of infected travelers. With approximately 25 million unvaccinated adults in the US, the CDC recommends vaccination before any international travel and additional doses for domestic travelers to Texas, where over 700 cases have been reported. This follows reports of measles cases at major airports and a significant increase in infections this year. Stanford research projects a potential surge in measles cases if vaccination rates decline further.
