L.A. County has its first measles case since 2020: What to do if you’re exposed
LA TimesThe best way to prevent measles infection is by getting the MMR vaccine, which covers measles, mumps and rubella, experts say. A recently arrived traveler at Los Angeles International Airport is the source of the first case of measles in L.A. County since 2020. L.A. public health officials are notifying Turkish Airlines passengers who sat close to this flier about possible measles exposure. The measles virus can live in the air for up to two hours after an infected person has left the area, according to the U.S. Centers for Disease Control and Prevention, which works with the L.A. Department of Public Health to investigate communicable disease exposure on international flights to the U.S. People who have not had measles infection or received the measles immunization previously may not be protected from the virus and should talk with a healthcare provider about receiving the measles, mumps and rubella immunization.
