Measles is highly contagious and can be serious. Measles is easily spread when an infected person breathes, coughs, or sneezes. Almost everyone who has not had the vaccine or measles previously will get measles if they are exposed to the measles virus.
The department urges everyone to check their own and their children’s immunization records to verify that they’re fully immunized. You can check your immunization status through the DOH website.
