How is Influenza Spread?
Influenza is spread through others that have the virus. They cough, sneeze, or talk and add droplets to the air that are then transferred to others. They will often land in the mouth or nose of an uninfected person, and cause the spread of the illness.
Some believe that it can also be caused surface contact if the virus is on a surface that is touched by someone. That person then touches their mouth, eyes, or nose and the disease is spread to that person.
