The flu, its causes, symptoms and treatments


nfluenza or influenza is a respiratory disease caused by a virus. The flu is highly contagious and is usually transmitted by coughing and sneezing of an infected person.

You can also get the flu by being in contact with an infected person (eg, shaking hands). Adults can be infected 1 to 2 days before symptoms appear and up to 7 days after becoming sick.

This means that the influenza virus can spread before people know they are infected.

More than 200,000 people in the United States are hospitalized for flu complications each year and it is estimated that about 36,000 people die from this disease.

It is estimated that between 250,000 and 500,000 people die every year as a result of the flu worldwide. In industrialized countries, the majority of deaths occur among people over 65.

A country affected by an epidemic of this disease in which a large number of people are infected, may take several weeks to control the situation.
