About Influenza

Influenza - the flu - is familiar to all of us. It's so common, in fact, that we often forget how serious it can be. Each year, influenza causes 3 to 5 million cases of severe illness and 250,000 to 500,000 deaths around the world1. In the United States alone influenza results in an estimated:

9.2-36 million

111 million
lost workdays3

91 million
lost schooldays4

It's estimated that only about 1 in 18 children, 1 in 38 elderly and 1 in 45 adults5 who get influenza will seek medical attention, so the disease is likely much more widespread than we know.
