Louisiana, Missouri and Virginia have all reported their first measles cases in 2025, and they say all three patients’ cases are linked to international travel.

The most recently announced case in northwest Virginia is a child in the 0 to 4-year age range who had recently traveled internationally, according to the state’s health department. Officials did not clarify if the child was vaccinated against the virus.

“This first case of measles in Virginia this year is a reminder of how easily this highly contagious disease can spread, particularly with international travel,” said state epidemiologist Laurie Forlano. “Vaccination remains our best defense against measles and is safe and highly effective at protecting people and preventing outbreaks.”
