The measles outbreak that started in Texas this year is likely larger than reported, a U.S. Centers for Disease Control and Prevention official said on April 15.

“We do believe that there’s quite a large amount of cases that are not reported,” Dr. David Sugerman, a senior CDC scientist working on measles, said during a meeting with the agency’s vaccine advisory panel.
