Flu is caused by a germ, also called a virus which infects the nose, throat, and lungs. The flu virus spreads from person to person mostly by the germs that are coughed and sneezed out into the air. Once you are infected, symptoms start between 1-4 days later, with an average of 2 days.
Adults typically can spread the virus to others from the day before their symptoms begin. They can stay infectious as long as 5 days after their illness starts.
