From this:

The Obama administration declared a “public health emergency” Sunday to confront the swine flu - but is heading into its first medical outbreak without a secretary of Health and Human Services or appointees in any of the department’s 19 key posts.

President Barack Obama has not yet chosen a surgeon general or the head of the Centers for Disease Control and Prevention. His choice to run the Food and Drug Administration awaits confirmation.

Obama spokesman Robert Gibbs says no worries, there's a team in place running day-to-day operations: "I think it’s all hands on deck, and we’re doing fine."
