What is measles in children?

Measles (rubeola) is a respiratory illness caused by a virus. It causes a red, blotchy rash. It's also known as 10-day measles or red measles. It's an infection that spreads very easily to other people (contagious).

The measles virus lives in the mucus in the nose and throat. It's spread from one child to another through contact with fluid from the nose and throat. It's also spread by an infected child coughing and sneezing.

What causes measles in a child?

Measles is caused by a virus. It's mostly seen in the winter and spring.

Which children are at risk for measles?

Children are more at risk for measles if they have not had the measles vaccine and are in contact with someone who has measles. A person is contagious about 4 days before the rash breaks out, so a child may have contact with the virus without knowing it.

What are the symptoms of measles in a child?

It may take 7 to 14 days for a child to show symptoms of measles after contact with the virus. A child is contagious about 4 days before the rash breaks out and 4 days after. A child may pass the virus to others before you know they have it.

The early part of the illness lasts between 1 and 4 days. Symptoms are like those of an upper respiratory infection. The most common symptoms include:

• Runny nose.

• Hacking cough.

• Pink eye (conjunctivitis).

• Fever.

After 2 or 3 days, other symptoms include:

• Severe diarrhea.

• Small spots with white centers (Koplik spots) on the inside of the cheek.

• Deep, red, flat rash that starts on the face and spreads down to the torso, arms, legs, and feet.

The red rash starts as small spots that combine into one big rash. After 3 to 7 days, the rash will start to go away. It will fade in the same order it appeared. It then leaves a brown-colored area and peeling skin.

The symptoms of measles can be like other health conditions. Make sure your child sees their doctor for a diagnosis.

How is measles diagnosed in a child?

The doctor will ask about your child's symptoms and health history. They may also ask about your family's health history. They will give your child a physical exam. The physical exam will include looking at the rash. The measles rash is different from other rashes. Your child may also have tests, such as blood or urine tests, to confirm the diagnosis.

How is measles treated in a child?

There is no specific treatment for measles. Treatment includes fluids, rest, and medicines for fever or discomfort. Treatment will depend on your child's symptoms, age, and general health. It will also depend on how bad the condition is. Antibiotics are not used to treat this illness.

The goal of treatment is to help ease symptoms. Treatment may include:

• Making sure your child drinks more fluids.

• Giving acetaminophen or ibuprofen for fever and discomfort.

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

If your child is younger than 1 year old, has a weakened immune system, or is admitted to the hospital with respiratory problems, your child's doctor may recommend an antiviral treatment called ribavirin.

Talk with your doctors about the risks, benefits, and possible side effects of all medicines. Don't give ibuprofen to a child younger than 6 months old unless your doctor tells you to. Do not give aspirin to children or teens unless your child’s doctor says it is safe. Aspirin can put your child at risk for Reye syndrome, a rare but serious condition.

If your child was exposed and has not had a measles vaccine, your child's doctor may give the MMR vaccine within 72 hours. Or the doctor may give immune globulin (IG) within 6 days of measles exposure. These are to help prevent the disease.

What are possible complications of measles in a child?

The most serious complications from measles include:

• Ear infection.

• Lung infection (pneumonia).

• Croup.

• Inflammation of the brain (encephalitis).

• Blindness.

How can you help prevent measles in your child?

The measles vaccine is usually given as part of a combination vaccine with mumps and rubella. It's called the MMR vaccine. The MMR vaccine is very safe and works well. It's given in 2 doses. The first dose is given between ages 12 months to 15 months. A second dose is given between ages 4 and 6 years. The second dose needs to be given at least 4 weeks after the first dose. During an outbreak, your child may need another booster shot.

Some children may need the MMR vaccine earlier if they:

• Live in an area with a measles outbreak.

• Need to travel to an area with a measles outbreak.

• Need to travel outside of the U.S.

Other ways to prevent the spread of measles include:

• Keeping children home from school or child care for 4 days after the rash appears.

• Checking that all of your child's friends and caregivers have been vaccinated.

When should you contact your child's doctor?

Contact the doctor if your child has:

• Symptoms that don't get better, or that get worse.

• New symptoms.
