About Influenza

Influenza is a contagious lung disease caused by the influenza virus.  There are several types of flu that cause illness and even death each year.  Take a moment to learn about the different types of flu, common symptoms and when to seek medical treatment.  If you have a lung disease, like asthma or COPD, you are more likely to suffer from complications from getting the flu.  Pneumonia is the most common complication of the flu. Protect yourself and prevent flu infection by getting a flu shot each year and learning good health habits.

There are many resources available to people infected with influenza.  We have information and tools created by the American Lung Association for your use.  And there are resources provided by partners of the American Lung Association.  Be sure to check out the other areas of our Influenza section.
