Measles is a childhood infection caused by a virus. Once quite common, measles can now almost always be prevented with a vaccine. Signs and symptoms of measles include cough, runny nose, inflamed eyes, sore throat, fever and a red, blotchy skin rash.
Also called rubeola, measles can be serious and even fatal for small children. While death rates have been falling worldwide as more children receive the measles vaccine, the disease still kills more than 100,000 people a year, most under the age of 5.
As a result of high vaccination rates, measles has not been widespread in the United States for more than a decade. Today, the United States averages about 60 cases of measles a year, and most of them originate outside the country.

Measles signs and symptoms appear 10 to 14 days after exposure to the virus. Signs and symptoms of measles typically include:
The infection occurs in sequential stages over a period of two to three weeks.
Acute illness and rash. The rash consists of small red spots, some of which are slightly raised. Spots and bumps in tight clusters give the skin a splotchy red appearance. The face breaks out first, particularly behind the ears and along the hairline.
Over the next few days, the rash spreads down the arms and trunk, then over the thighs, lower legs and feet. At the same time, fever rises sharply, often as high as 104 to 105.8 F (40 to 41 C). The measles rash gradually recedes, fading first from the face and last from the thighs and feet.

Call your doctor if you think you or your child may have been exposed to measles or if you or your child has a rash resembling measles. Review your family's immunization records with your doctor, especially before starting elementary school, before college and before international travel.

The cause of measles is a virus that replicates in the nose and throat of an infected child or adult.
When someone with measles coughs, sneezes or talks, infected droplets spray into the air, where other people can inhale them. The infected droplets may also land on a surface, where they remain active and contagious for several hours.
You can contract the virus by putting your fingers in your mouth or nose or rubbing your eyes after touching the infected surface.

Your doctor can usually diagnose measles based on the disease's characteristic rash as well as a small, bluish-white spot on a bright red background — Koplik's spot — on the inside lining of the cheek. If necessary, a blood test can confirm whether the rash is truly measles.

If someone in your household has measles, take these precautions to protect vulnerable family and friends:
Isolation. Because measles is highly contagious from about four days before to four days after the rash breaks out, people with measles shouldn't return to activities in which they interact with other people during this period.
It may also be necessary to keep nonimmunized people — siblings, for example — away from the infected person.

If you've already had measles, your body has built up its immune system to fight the infection, and you can't get measles again. Most people born or living in the United States before 1957 are immune to measles, simply because they've already had it.
For everyone else, there's the measles vaccine, which is important for:
Promoting and preserving herd immunity. Since the introduction of the measles vaccine, measles has virtually been eliminated in the United States, even though not everyone has been vaccinated. This effect is called herd immunity.
But herd immunity may now be weakening a bit. The rate of measles in the U.S. recently tripled.
Preventing a resurgence of measles. Soon after vaccination rates decline, measles begins to come back. In 1998, a now-discredited study was published erroneously linking autism to the measles, mumps and rubella (MMR) vaccine.
In the United Kingdom, where the study originated, the rate of vaccination dropped to an all-time low of just under 80 percent of all children in 2002. Between 2012 and 2013, more than 1,200 children in the U.K. contracted measles, up from 380 children in 2010.
