Measles may become ‘endemic’ without vaccination, proper clinical diagnosis, CDC official saysThe number of measles cases reported in the U.S. in January has surpassed the total median number of cases in previous years, and more adults are contracting the virus, the Centers for Disease Control and Prevention (CDC) said during a telebriefing Thursday afternoon. The virus is also being traced back to a greater number of places than in previous years, according to the CDC. As of Thursday, Jan. 29, 84 measles cases had been reported in 14 states. The median number of measles cases from 2001 to 2010 was only 60 cases, said Anne Schuchat, assistant surgeon general for the United States Public Health Service and the CDC’s national Center for Immunization and Respiratory Diseases. “This worries me,” Schuchat said, “and I want to do everything possible to prevent measles from getting a foothold in the U.S. and becoming endemic.” The majority of the reported measles cases for the current outbreak stem from an outbreak at the Disneyland resorts in California. Since Dec. 28, 2014, an estimated 67 measles cases have been linked to the resort. Schuchat said the first person to spread measles at Disneyland likely traveled from another country and brought the virus back to the U.S. The virus has been spread to six additional states since the first reported case at Disneyland.
