The West Virginia Bureau for Public Health was notified of a confirmed case of measles at Washington Dulles International Airport on March 5, 2025. The agency says West Virginia residents could have been exposed.

The confirmed case was an individual who was returning from international travel and is a Maryland resident. Public officials believe West Virginia residents may have been exposed.

Measles is a highly contagious disease that can spread through the air when a person breathes, coughs or sneezes. It is preventable through a safe and effective vaccine – the MMR shot that provides immunity to measles, mumps and rubella – and health officials said in 2000 that the virus had been eliminated in the United States.
