A flu pandemic is a global outbreak of a new (novel) flu A virus in people that is very different from current and recently circulating seasonal flu A viruses.
A pandemic flu will likely infect many people because few people will have immunity to it. A vaccine may not be widely available in the early stages of a pandemic.
Flu pandemics happen rarely. Four flu pandemics have happened in the past 100 years, but experts agree that another one is inevitable. Although it is impossible to predict when the next pandemic will occur, Federal, State and local health departments are working to coordinate and improve efforts to prevent, control and respond to viruses with pandemic potential.
Planning for a flu pandemic assumes that many people will be ill and not able to work. Assume that disruptions may occur in services (including utilities, grocery stores and other businesses), and that schools and day care may close temporarily. Plan to take care of yourself and your family at home as much as possible. Keep a supply of non-perishable food and water that will last at least three to four days. Keep adequate supplies of prescription and non-prescription medications on-hand. Volunteer with local groups to learn more, and to help prepare and assist with emergency response.
If a pandemic influenza does occur, follow instructions from your local public health authorities. For more information, visit the Centers for Disease and Prevention's website at cdc.gov/flu/pandemic
