Measles is an infectious disease caused by a virus. It spreads easily from person to person. It causes a blotchy red rash. The rash often starts on the head and moves down the body. Other symptoms include

• Fever
• Cough
• Runny nose
• Conjunctivitis (pink eye)
• Feeling achy and run down
• Tiny white spots inside the mouth

Sometimes measles can lead to serious problems. There is no treatment for measles, but the measles-mumps-rubella (MMR) vaccine can prevent it.

\'German measles\', also known as rubella, is a completely different illness.
