MEASELS
Overview
Measles, also called rubeola, was once a common childhood illness. It's caused by a virus that spreads easily through the air and settles on surfaces. A vaccine can prevent measles infection.
Most people recover from measles in about 10 days. It usually doesn't cause long-term medical issues. But measles can be serious and even deadly. This is especially true for children younger than age 5 and people with severely weakened immune systems.
Measles is treated by managing symptoms and preventing complications.
Get a measles vaccine when recommended to keep the virus from spreading. Because of vaccination, measles hasn't been common in the United States for more than two decades. Often, measles cases in the U.S. come from outside the country. Outbreaks are more common among people who are not vaccinated.
