Measles

Measles, also called rubeola, is a highly contagious - but rare - respiratory infection that's caused by a virus. It causes a total-body skin rash and flu-like symptoms, including a fever, cough, and runny nose.
Since measles is caused by a virus, symptoms typically go away on their own without medical treatment once the virus has run its course. But while your child is sick, it's important to make sure that he or she has plenty of fluids and rest, and to keep your child from spreading the infection to others. If you have any concerns about your child's condition, talk to your child's doctor.
