On April 14, the World Health Organization (WHO) posted information regarding the international increase in measles cases. To date in 2011, 24 countries in the European Region are experiencing large measles outbreaks that are spreading between countries and to other regions of the world. France has had the largest outbreak, with 3,749 measles cases officially reported in January and February 2011. This included eight people who suffered neurological complications, and one person who died due to measles-related pneumonia.

CDC reports that in January and February 2011, a total of 29 cases of measles were identified in the U.S. – 28 of these were associated with importation. As of April 9, 2011 there have been 42 cases reported for 2011, compared to a total of 61 cases reported in 2010. Outbreaks are currently occurring in Minnesota and Utah. In New England, cases have been reported in Massachusetts and Rhode Island. No cases of measles have been reported in Vermont since 2001.

Measles is a highly communicable viral respiratory disease that causes an estimated 10 million cases and 164,000 deaths worldwide each year. Due to widespread immunization starting in the late 1960s, measles was declared eliminated from the United States in 2000. Importation of measles from other countries still occurs. Lower rates of vaccine acceptance associated with parental concerns regarding the MMR vaccine allows for continued transmission of sporadic cases of measles. The greatest risk is for infants under 1 year of age, still too young to receive MMR immunization.
