Measles is highly contagious and spread through the air, according to the CDC. The disease is especially dangerous for children younger than 5. It was declared eliminated in the U.S. in 2000.
Measles symptoms include fever, cough, runny nose, red, watery eyes and fatigue. Measles is often characterized by a spotted rash that appears three to five days after the initial symptoms, according to the health department.
According to the CDC, the best way to prevent measles is with the MMR vaccine.
