The Flu is a contagious respiratory illness caused by influenza viruses (Type A or Type B) that infect the respiratory tract. During the winter season, influenza makes up the majority of diseases.
Flu can manifest itself in the form of headaches, sluggishness, body aches and a runny nose. It can also produce deadly, serious or fatal symptoms, including:
The influenza virus is the primary cause of the flu. Keep in mind that there are many strains of the flu virus, and they constantly evolve each year.

Flu vaccination is still the best form of protection against the influenza virus.
Vaccines can lessen the risk and seriousness of the disease. Because the influenza virus constantly changes through a process called antigenic drift, every year, there are new flu vaccines to protect individuals against the new strains.
