Measles Fact Sheet

Radnor New Seal

According to the CDC, since early 2019, there have been over 500 cases of measles confirmed in 20 states

Outbreaks can occur for reasons such as:

  • An increase in the number of traveler's who bring it back to the US
  • And/or spreading of measles in communities with areas of unvaccinated people

Measles is a highly contagious virus that lives in the nose and throat of an infected person and it can spread:

  • When an infected person coughs or sneezes
  • Measles virus can live for up to two hours in air when the infected person coughs or sneezes
  • If others breathe in the contaminated air or touch an infected surface and then touch their eyes, nose or mouths, they too can become infected
  • Up to 90 % of the people who are close to that person and not immune, also become infected Infected people can spread measles up to 4 days before and 4 days after the rash appears

Symptoms usually appear within 7-14 days after the person is infected and Measles symptoms typically begin with :

  • High fever, cough, runny nose, red, watery eyes (conjunctivitis)
  • 2-3 days after symptoms begin, tiny white spots (Koplick Spots) may appear inside the mouth
  • 3-5 days after symptoms begin, a rash breaks out
  • The red spots usually start out flat, on the face or around the hairline, and work their way down the body
  • Raised spots may appear on top of the flat ones as they spread
  • Once the rash appears, high fever may develop

Your best protection against Measles is the Measles-Mumps-Rubella (MMR) vaccine
