WASHINGTON (CNN) - Obama senior advisor Valerie Jarrett told CNN Sunday the president takes the swine influenza outbreak "very seriously," as the White House announced an afternoon briefing to provide an update on efforts to keep the disease from spreading to the United States.
Secretary of Homeland Security Janet Napolitano and acting CDC director Dr. Richard Besser will speak at 12:30. The State Department is also involved in tracking efforts.
This week, isolated cases of the illness were reported in at least three states. The swine flu has stricken more than a thousand and been blamed for more than 80 deaths in Mexico over the past few weeks.
