Influenza, often called the ‘flu’, is an infection of the nose, throat and lungs caused by an influenza virus.
A person with influenza is also at risk of other infections. These include viral or bacterial pneumonia, an infection of the lungs. The risk of complications is greater for seniors 65 years and older, very young children, and people who have lung or heart diseases, certain chronic health problems, or weakened immune systems. Healthy pregnant women in the second half of their pregnancy are at greater risk of being hospitalized following infection with seasonal influenza virus.
In Canada, it is estimated that between 2,000 to 8,000 people die from seasonal influenza and its complications every year.
