As of August 26, 198 cases and 15 outbreaks of measles had been confirmed in the United States, the highest number since 1996 (CDC, unpublished data, 2011). Of the 198 cases, 179 (90%) were associated with U.S. residents traveling internationally. Of the 15 outbreaks, the outbreak in Indiana is the second largest. With ongoing importation and suboptimal vaccination rates among specific populations, measles outbreaks might continue to occur.2 In addition to providing accurate information on the risks and benefits of vaccines and making vaccination accessible, state and local health departments should continue to investigate contacts of suspected measles patients to institute control measures to prevent measles transmission in the community. Parents should be reminded, as children return to school, to check their children's vaccination status for measles, mumps, and rubella vaccine and all other recommended vaccines.
