Last year was the worst year for measles in the U.S. in 15 years the CDC has announced.
There were 222 cases of measles, a large jump from the 60 or so seen in a typical year. Most of the cases last year were imported — either by foreign visitors or by U.S. residents who picked up the virus overseas.
Generally, the Americans who got measles last year were not vaccinated. At least two-thirds of the U.S. cases fell into that category, including 50 children whose parents got philosophical, religious or medical exemptions to skip the school vaccinations required by most states, CDC officials have said.
Measles is highly contagious. The virus spreads easily through the air, and in closed rooms, infected droplets can linger for up to two hours after the sick person leaves. It causes a fever, runny nose, cough and a rash all over the body.
