Measles is a highly contagious disease that can be prevented by vaccination. It is still found in many EU countries where vaccination coverage is low. Outbreaks have been reported this year in several schools in Berlin, Germany.
In the United States, more than 100 people have contracted measles in several states by early February 2015. Cases have also been found in Canada and Mexico. The Philippines saw a major measles outbreak in 2014, caused by the same type as the virus found in California.
