Measles is a highly contagious disease caused by a virus that can spread through the air when an infected person coughs or sneezes or if someone comes into direct contact or shares germs. Symptoms may include fever, cough, runny nose, watery eyes and a rash of red spots.
Measles cases in the U.S. surpassed the highest number on record since the disease was declared eradicated in 2000.
