Influenza, also known as the flu, is a contagious disease that is caused by the influenza virus. It attacks the respiratory tract in humans (nose, throat, and lungs). The flu is different from a cold. Influenza usually comes on suddenly and may include these symptoms: fever, headache, tiredness (can be extreme), dry cough, sore throat, nasal congestion and body aches. These symptoms are usually referred to as "flu-like symptoms."

Influenza A viruses periodically cause worldwide epidemics, or pandemics, with high rates of illness and death. Unlike other public welfare emergencies, an influenza pandemic will impact on multiple communities across the United States and require swift and coordinated action and cooperation by all levels of government. Advanced planning for a large scale and widespread health emergency is required to optimize health care delivery during a pandemic. In addition, prevention and preparedness activities facilitate the response and recovery during and after an influenza pandemic.

Sample Q&A: The Disease

What is pandemic influenza?
Pandemic influenza occurs when a non-human (novel) influenza virus gains the ability for efficient and sustained human-to-human transmission and spreads globally, causing serious illness.  Pandemic viruses emerge when there is a major change in the proteins on the surface of the virus, resulting in a new subtype of the influenza virus.  Animals are the most likely reservoir for these emerging new influenza subtypes; such as birds, known as avian influenza or pigs known as swine flu.  

Because the virus is new, the human population has little to no immunity against it.  The virus spreads quickly from person-to-person worldwide.  Pandemics may occur outside fall and winter, the traditional flu season.  While people may have some immunity to seasonal outbreaks of influenza, they may not have immunity to a pandemic strain, because it comes from a new kind of influenza virus.
