Experts believe that the flu usually spreads through the flu cough, sneeze, or droplets produced when speaking. This is especially true if those droplets enter the mouth or nose of nearby people. You can also get the flu (although less often) by touching a surface or object with the flu virus and then touching your mouth, eyes, or nose. The flu is as severe as possible, but the good news is that most people feel much better within a week or two. Most healthy adults are transmitted the day before symptoms appear (it becomes difficult to prevent their spread). It will continue to be infected for up to 5-7 days after symptoms appear. However, children and people with weakened immunity may continue to be infected for longer.
