Common causes of the flu

Viruses of the flu travel through air in droplets when an infected person coughs, talks or sneezes. The droplets can either be inhaled directly or be picked from germs from an object. People with the virus are likely to be more contagious on the day before symptoms of flu first appear, until the first 5 days after the symptoms begin. The ones who are more contagious include children and people with a weak immune system.

A person who is suffering from the flu in the past has made antibodies which can fight that particular strain of the virus. These antibodies work towards reducing severity of a consecutive infection and even preventing further infection.

A young and healthy person will not suffer from too serious seasonal influenza. The flu is likely to vanish within a week or two without any long lasting effects. However, children and people with weakened immune systems may develop complications such as ear infections, bronchitis, asthma flare-ups, pneumonia and heart problems.
