China's New Bird Flu Strain Has Killed 10

CDC working on test for virus


After China reported 38 cases of a new, highly virulent flu strain that has killed 10 people, U.S. health agencies are moving into high gear to combat it.

This week, the Centers for Disease Control and Prevention activated its Emergency Operations Center at Level II, the second-highest level of alert. CDC staffers working on the outbreak who aren't in laboratories moved to the operations center for efficiency.

"It's to ensure that we don't have any loose ends," CDC director Thomas Frieden said.
