Measles is an infection that spreads easily. It causes fever, cough, fatigue, runny nose, conjunctivitis, and a rash. It was once a common childhood illness, but it is now less common in the United States due to the use of the measles vaccine .

Measles is caused by a virus. The virus is spread by:
- Direct contact with nasal or throat secretions of infected people, such as through kissing
- Airborne transmission, which is less common, such as through coughing and sneezing
Measles can be spread:
- 1-2 days before symptoms appear
- 3-5 days before the rash
- Up to 4 days after the appearance of the rash
Factors that may increase your risk of measles include:
- Unvaccinated or inadequately vaccinated
- Living in crowded and/or unsanitary conditions
- Traveling to less developed countries where measles is common
- Season: winter and spring
- Weakened immune system even if vaccinated
Born after 1956 and either:
- You have never been diagnosed with measles
- You received a vaccine before 1968 and you have never been fully vaccinated since
Measles symptoms generally appear 8-12 days following exposure. They include:
- Fever, often high
- Runny nose
- Red eyes
- Hacking cough
- Sore throat
- Very small whitish spots inside the mouth—2-4 days after initial symptoms
Raised, itchy red to brownish rash:
- Starts around the ears, face, and side of the neck 3-5 days after the first symptoms appear
- Generally spreads to the arms, trunk, and legs over the next 2 days
- Lasts about 4-6 days
Full recovery, without scarring, generally takes 7-10 days from the onset of the rash.
Measles is caused by a virus. It cannot be treated with antibiotics. The focus is on relieving symptoms with rest and comfort measures such as:
- Gargling with warm salt water
- Using a humidifier
- Over-the-counter pain relievers
- Cold sponge baths
- Drinking plenty of liquids and eating a soft, bland diet
In most cases, complications are rare. You may need to be hospitalized if you have a severe case. Complications may include:
- Inflammation of the brain— encephalitis
- Bacterial pneumonia
Getting vaccinated is the best way to prevent measles. The vaccine contains live viruses that can no longer cause disease. There is a single vaccine to prevent measles. It is also available in combination with:
- Mumps and rubella vaccine (MMR)
- Mumps, rubella, and varicella (chickenpox) vaccine (MMRV)
The regular schedule for giving the vaccine is at age 12-15 months and again at age 4-6 years. If you or your child has never been vaccinated against the measles, talk to the doctor.
In some cases, the MMR vaccine is given within 3 days after exposure. This can prevent or reduce symptoms. Immune globulin is given to certain unvaccinated people within 6 days of exposure. This is usually for infants and pregnant women.
If you or someone in your family gets measles, family members may need to be vaccinated or given immune globulin.
If you are not vaccinated, avoid contact with someone who has measles. Recent outbreaks of measles have occurred in Europe and the United States. They may have been caused by increasing numbers of children who are not vaccinated. Discuss the benefits of vaccination with your doctor.
