Transmission of Measles
Measles is highly contagious. 90% of persons without immunity to measles will become ill after exposure to the virus. Importantly, measles can be transmitted before the characteristic rash develops. Measles virus can persist in the air for hours AFTER an ill person has left. Therefore, an individual can be exposed even without being in the same place at the same time as a measles case.

Signs and Symptoms
Measles symptoms don’t appear immediately after exposure. Illness often starts with respiratory symptoms and eventually a rash develops.
Measles symptoms appear 7-14 days after contact with the virus and typically include a high fever, cough, runny nose, and watery eyes.
Measles rash appears 3-5 days AFTER the first symptoms.
Call your healthcare provider immediately if you think you or your child have been exposed.
Call ahead before visiting a healthcare setting to be evaluated for measles.

Planning an International Trip?
Measles cases in the United States usually originate with unvaccinated people who get infected in other countries. Typically, 2 out of 3 of these unvaccinated travelers are Americans. They can spread measles to other people who are not protected against measles, which sometimes leads to outbreaks.
Since measles is still common in many countries, unvaccinated travelers bring measles to the United States, and it can spread. Protect yourself, your family, and your community with the MMR vaccine, especially before traveling internationally.To find out more about CDC's health recommendations for your travel destination, visit:
