1. Pandemic Influenza or sometimes called Pandemic Flu is a new human flu virus that has changed significantly from previous human flu viruses. Because it is so different, people have little natural protection (immunity) and the disease can spread easily from person to person and cause a global outbreak, or pandemic, of serious illness.

2. A pandemic influenza, or pandemic flu, occurs when a new subtype of influenza virus:
- (1) develops and there is little or no immunity (protection due to previous infection or vaccination) in the human population;
- (2) it is easily passed from human to human;
- (3) is found in many countries; and
- (4) causes serious illness in humans. Also see influenza, seasonal influenza, and avian influenza.
