"Measles is a viral infection that can present in a number of ways, typically referred to as the three Cs: cough, coryza and conjunctivitis, plus fever and then a rash," says Dr. Nipunie Rajapakse, a pediatric infectious diseases specialist at Mayo Clinic. Measles in highly contagious and spread through coughing and sneezing.

Initial symptoms of measles include:
"The typical rash progression usually starts at the head and works its way down, but that doesn’t happen in all cases. Kids can feel quite miserable, like with many other viral infections, but there are some serious complications that can develop as well," says Dr. Rajapakse.
Complications from measles can range from an ear infection or diarrhea to more severe medical problems such as encephalitis. Dr. Rajapakse says measles can cause "Inflammation or swelling in the brain that can leave someone with lasting neurologic or brain damage. It can cause inflammation or swelling in the heart or lungs as well."
The severe complications can be long-lasting and possibly lead to death. The CDC says out of 1,000 children infected with measles, one or two children will die.
"It's completely unnecessary because we have an excellent vaccine that prevents this infection," says Dr. Rajapakse. "We know that one dose of measles, mumps and rubella (MMR) vaccine is about 93% effective. Two doses, which is the recommendation, is about 97% effective. Any childhood case of measles or death from measles is completely preventable at this point."
The Centers for Disease Control and Prevention recommends all children get two doses of MMR vaccine, starting with the first dose at 12–15 months and the second dose at ages 4–6.
