Measles
Measles is a very contagious viral illness. It can be prevented with a vaccine. Measles is also known as rubeola. It causes a distinct rash and a fever. Measles can spread through direct person to person contact or through breathing air with infected droplets. Each cough or sneeze from an infected person releases thousands of virus particles into the air. In the case of measles, the virus remains infectious in the air for two hours. The symptoms of measles happen about 7 to 14 days after coming in contact with a person with the virus.
What are the symptoms of measles?
Measles often starts with cold-like symptoms, such as:
-
High fever (up to 104°F (40°C) or higher
-
Runny nose
-
Inflammation and redness of the covering of the white part of the eye (conjunctivitis)
-
Cough
-
Tiny white spots inside the mouth (Koplik spots)
Within another few days, a red rash appears. It often starts on the face and then spreads to the rest of the body. Once the rash appears, the fever may get much higher. This rash fades after 4 to 7 days as symptoms go away.
The symptoms of measles may look like other health problems. Make sure your child sees their healthcare provider for a diagnosis.
How is measles treated?
There is no specific treatment for measles. Treatment is supportive, meaning 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 severe the condition is.
Your child's treatment may include:
-
Medicine for fever or discomfort
-
Antibiotic medicine for complications, such as bacterial infections that may develop. Antibiotics are not effective in treating viral infections like measles.
-
Hospitalization if complications develop or your child is too sick to be taken care of at home.
-
Vitamin A if recommended by your child's doctor. It can lessen the severity of the illness and the chance of serious complications in some children. Vitamin A does not prevent measles. It is not a substitute for vaccination.
What are possible complications of measles?
Most children get better with no lasting effects. But measles can lead to serious complications or even death. Up to 30% of children will experience a complication, ranging from mild to severe. Complications of measles are:
-
Middle ear infection that may lead to hearing loss
-
Infection of the lungs (pneumonia)
-
Infection of the upper airway with trouble breathing and cough (croup)
-
Diarrhea
-
Infection of the brain (encephalitis)
How can measles be prevented?
The measles vaccine is part of the routine vaccines recommended for children. Children should be vaccinated for measles with 2 doses:
For children who have not been vaccinated, getting the vaccine up to 3 days after exposure to measles may prevent the disease.
Children who have had measles are immune for life.
When should I call my healthcare provider?
Call your child's healthcare provider right away if you suspect measles. Get emergency care if your child has:
