What is the flu? The flu is an infection that spreads easily and is caused by the influenza virus.

It primarily attacks the respiratory system and can lead to pneumonia, and even death. There are three types of the virus: types A, B and C, but it is type A that causes the most illness. The infection can in fact be serious, as over 200,000 people are hospitalized each year because of the flu and over 36,000 people die. But is the flu preventable? In this video, Dr. Holly Atkinson explains ways we can catch the flu, as well as some helpful tips to avoid it. The virus is constantly mutating and adapting so as humans we must do the same.
