*About Measles*

Measles [ [link removed] ] is highly contagious and spreads through the air when an infected person coughs, sneezes, breathes, or talks. The virus can remain airborne for up to two hours, meaning people can get infected even after a sick person has left the area. Measles can cause serious health complications, especially for babies and young children.

Symptoms (appear 7-21 days after exposure):


* High fever, cough, runny nose
* Red, watery eyes
* Rash which begins on the face and spreads down the body

If you have symptoms or believe you were exposed to measles, call your healthcare provider right away. For infants too young to receive vaccine and susceptible individuals who have been exposed but have not developed symptoms, the _measles, mumps, and rubella (MMR) vaccine [ [link removed] ]_ or immune globulin given within 72 hours of exposure can reduce the risk of developing measles.

*Prevention: The MMR Vaccine*

The measles, mumps, and rubella (MMR) vaccine [ [link removed] ] is the strongest protection against measles and is safe and highly effective: one dose is 93% effective and two doses are 97% effective.

Getting the MMR vaccine is safer than getting sick with measles, and it protects your family and your community. Children normally get the MMR vaccine at 1 year and 4 years of age. If you haven’t been vaccinated against measles as a child, you can get the MMR vaccine an adult. Most people who get measles are unvaccinated.
