What is measles?

Measles is a very contagious (easily spread) infection that causes a rash all over your body. It is also called rubeola or red measles.

The measles vaccine protects against the illness. This vaccine is part of the MMR (measles, mumps, and rubella) and MMRV (measles, mumps, rubella, and varicella [chickenpox]) vaccines. Most children get the vaccine as part of their regular shots. This is why measles is rare in the U.S. and Canada.

 

What causes measles?

Measles is caused by a virus. It is spread when an infected person coughs, sneezes, or shares food or drinks. The measles virus can travel through the air. This means that you can get measles if you are near someone who has the virus even if that person doesn't cough or sneeze directly on you.

You can spread the virus to others from 4 days before the rash starts until 4 days after the rash appeared. The virus is most often spread when people first get sick, before they know they have it.

If you have had measles, you can't get it again. Most people born before 1957 have had measles.

 

What are the symptoms?

The first symptoms of measles are like a bad cold-a high fever, a runny nose, sneezing, a sore throat, and a hacking cough. The lymph nodes in your neck may swell. You also may feel very tired and have diarrhea and red, sore eyes. As these symptoms start to go away, you will get red spots inside your mouth, followed by arash  all over your body.

When adults get measles, they usually feel worse than children who get it.

It usually takes 8 to 12 days to get symptoms after you have been around someone who has measles. This is called the incubation period.

How is measles diagnosed?

Your doctor will ask you about your symptoms and examine you. If your doctor suspects that you have measles, he or she may do a blood test and/or viral culture.

If you think you have measles, call your doctor so he or she can report the illness to the local health department.

 

How is it treated?

Measles usually gets better with home care. Take medicines to lower your fever. Also, get plenty of rest and drink lots of fluids. Stay away from other people as much as you can so that you don't spread the disease. If your child has measles, keep him or her out of school until at least 4 days after the rash first appeared. Keep your child out longer if he or she is not feeling well. Your doctor may suggest vitamin A supplements if your child has measles.

Most people get better within 2 weeks. But measles can sometimes cause dangerous problems, such as lung infection (pneumonia) or brain swelling(encephalitis). In rare cases, it can even cause seizures or meningitis.
