Measles was declared eliminated in the United States in 2000, but cases are still being imported from overseas. The Centers for Disease Control and Prevention (CDC) recorded a total of 288 confirmed measles cases from Jan. 1 through May 23, 2014, the highest reported yearly total since elimination and surpassing the previous high of 220 reported in 2011. The high number of cases emphasizes both the need for greater awareness among healthcare providers and the importance of vaccination. Measles cases this year have affected patients as young as two weeks and as old as 65 years, and 25 percent of cases involved patients aged five to 19 years. So far, there have been no related encephalitis cases or deaths reported. Most cases were reported from Ohio, California, and New York City. Ninety-seven percent of the cases were associated with importations from at least 18 countries. The CDC notes that most of the 288 cases have been in persons who were unvaccinated or had an unknown vaccination status.
