What is the flu?
Influenza (or “flu”) is a respiratory illness caused by a virus. Some people who get the flu can become very ill and need hospital care. The flu leads to thousands of deaths each year, mostly among the elderly. Young children and those with chronic health conditions are also at risk. In Canada, the flu season usually runs from November to April.
One of the most effective ways to protect yourself from the flu is to get the flu shot each year in the fall.
