Although influenza, commonly known as the flu, is a familiar disease to many people, its effects can be deadly. The virus holds the record for having the highest death rate in a two-year period of any disease (1918–1919), is highly potent, and is difficult to research because it is constantly mutating. Influenza, Third Edition examines symptoms and complications of the disease, as well as treatment, prevention, and the need for flu vaccines.
