Measles is a respiratory disease caused by a virus.
It causes fever, runny nose, tiredness, cough and a blotchy rash.
Because of the widespread use of the MMR vaccine, cases in the US are rare, but measles still kills 200,000 people worldwide each year.
Measles is spread through the air by breathing, coughing, or sneezing.
It is so contagious that any person who is exposed to it and is not immune will probably get the disease.
Measles can be spread to others from four days before to four days after the rash appears.
