Measles is caused by a highly contagious virus that spreads easily from person to person. It is an airborne disease, meaning it spreads through the air when an infected person breathes, coughs, sneezes, or talks. The virus can stay alive in the air and on surfaces for up to two hours. If one person has it, up to 9 out of 10 people nearby will become infected if they are not protected. Two doses of MMR (measles, mumps, rubella) vaccine are highly effective at preventing measles.
