Measles is highly contagious and can stay in the air for up to two hours after an ill person coughs or sneezes, and can stay on surfaces for several hours, health officials say. About 90 percent of people who are exposed and not immune to the illness become sick 7 to 21 days after exposure.
Measles symptoms include fever, dry cough, runny nose, sore throat and red, watery eyes. Three to five days after symptoms begin, the CDC says a rash breaks out which appears as flat red spots on the face at the hairline and spread downward to the neck, trunk, arms, legs and feet. Small raised bumps may also appear on top of the flat red spots.
