More than 220 measles cases have been reported this year as of March 6, largely associated with an outbreak at the border between Texas and New Mexico, according to the U.S. Centers for Disease Control and Prevention. Unvaccinated children make up the majority of confirmed cases.Still, the number of deaths suggests that the outbreak is much bigger than the official number, says infectious diseases physician Peter Chin-Hong of the University of California, San Francisco. Based on the expected fatality rate of 1 to 2 people per 1,000 infections, he says, the real number of cases may be closer to the high hundreds if not over 1,000.
