Preparation for the next influenza pandemic includes development of a national plan that has 3 goals: to limit the burden of disease, to minimize social disruption, and to reduce economic losses attributable to the pandemic. Priority areas to be addressed and improved in the plan to achieve these goals include global and national influenza surveillance, vaccine development and production, vaccine use and coverage, chemoprophylaxis and therapy, guidelines for clinical care and health resources management, emergency preparedness, and research. This multifaceted plan will require close collaboration between public and private sectors to ameliorate the potentially devastating impact of pandemic influenza.
