Measles is very contagious. It is spread mainly through respiratory droplets from infected people. Infected people are most contagious from about 4 days before their rash starts until 4 days afterwards. Routine measles vaccination of children in the U.S. has made measles a rare disease in the U.S. However, measles is still seen in this country, usually associated with a visitor to the U.S. or a U.S. traveler returning from other countries.  In 2011, multiple countries around the world are experiencing increases in measles cases, especially in Europe and Southeast Asia.  The increase in the number of measles cases reported in the U.S. thus far in 2011 has mainly been associated with importation but has resulted in local transmission and outbreaks as well.  All Orange County residents should make sure they are up-to-date on their measles vaccinations (usually given as MMR).  To see if you need measles vaccine, see the CDC recommendations.
