What is the Influenza A, H1N1 pandemic?
A pandemic is an epidemic of infectious disease that spreads across many international geographic areas. The recently declared pandemic concerns the spread of non-seasonal influenza, and does not reflect the severity of illness. Historical records indicate that there are typically several flu pandemics each century of varying severity. We are thought to be in the early phase of this pandemic, as pandemics typically last 1-2 years.
