Measles Transmission: How It Spreads & Prevention

Measles is a highly contagious respiratory infection caused by a virus. It is spread through contact with respiratory droplets produced by an infected person when they cough or sneeze. These droplets can land in the mouths or noses of people who are nearby, or they can be inhaled into the lungs. People can also become infected by touching something that has been contaminated with the virus and then touching their face or mouth.
