Measles — United States, January 1–May 23, 2014

In this report

Measles — United States, January 1–May 23, 2014  Paul A. Gastañaduy, MD, Susan B. Redd, Amy Parker Fiebelkorn,  MSN, et al. MMWR 2014;63:1–4.  Measles is a highly contagious, acute viral illness that can lead to serious  complications and death. Although measles elimination was declared in the  United States in 2000, importations of measles cases from endemic areas  of the world continue to occur, leading to secondary measles cases and  outbreaks in the United States, primarily among unvaccinated persons.  To update national measles data in the United States, CDC evaluated cases  reported by states from January 1 through May 23, 2014. A total of 288  confirmed measles cases have been reported to CDC, surpassing the  highest reported yearly total of measles cases since elimination.
