Who is at risk for measles?

Those most at risk for measles are:

• Children and adults who never had the measles vaccine.

• Infants too young to get the vaccine (under 1 year of age).

• People with weak immune systems, even if they’ve been vaccinated against measles.

• Adults vaccinated before 1968 who were given an inactivated (killed) measles vaccine or a measles vaccine of an unknown type. This vaccine was used between 1963 and 1967 and was not effective.

What are the symptoms of measles?

Early symptoms of measles include:

• A runny nose.

• A cough.

• Inflamed and red eyes (conjunctivitis).

• Fever.

• Rashes:

  • Tiny white spots inside the mouth called Koplik spots.

  • Red blanching spots that usually start on the face and spread downward.

The red spots of the rash appear 2 to 4 days later. The rash often starts on the face and then spreads to the rest of the body.

How is measles diagnosed?

Your doctor can often diagnose measles based on your child's symptoms. Lab tests can confirm the diagnosis.

How is measles treated?

There is no specific treatment for measles. It includes fluids, rest, and medicines for fever or discomfort. Your child may need:

• To be kept away from people, especially if they're not vaccinated.

• Medicine for fever.

• Antibiotics for bacterial infections if they develop. If your doctor prescribed antibiotics, give them to your child as directed. Do not stop giving them just because your child feels better. The full course of antibiotics needs to be taken.

• Vitamin A, if recommended by your child's doctor. In some children, it can reduce how severe the illness might become and lower the chance of serious problems. Vitamin A does not prevent measles. It is not a substitute for vaccination.

• A stay in the hospital if problems develop.

What are possible complications of measles?

Most children recover with no lasting effects. But measles can lead to serious problems or even death. Problems caused by measles can include:

• A middle ear infection.

• Infection of the lungs (pneumonia).

• Infection of the upper airway with trouble breathing and cough (croup).

• Diarrhea.

• Infection of the brain (encephalitis).

• Death.

How can measles be prevented?

Vaccination helps protect your child from measles.

The measles vaccine is part of the routine immunizations advised for children. Children should be vaccinated for measles with two doses:

• First dose at 12 to 15 months of age.

• Second dose at 4 to 6 years of age.

For those who have not been vaccinated, vaccination up to 3 days after exposure to measles may prevent or reduce the severity of the disease.
