The Spread of Influenza 

The virus of influenza spreads rapidly among people via the tiny droplets which are formed by people who talk, cough or sneezes while suffering from the influenza virus themselves. The droplets reach the other person and quickly land on their mouth or nose which they inhale and that leads to the spread of the virus. Sometimes these influenza or flu viruses spread when a person touches a surface or anything that was taken over by the flu virus and touches their face or nose or sometimes their eyes instantly.
