Usually, the influenza virus is spread through the air from coughs or sneezes. It can also be spread by touching surfaces contaminated by the virus and then touching the eyes, nose, or mouth.

Common symptoms of the flu such as fever, headaches, and fatigue are the result of the huge amounts of proinflammatory cytokines and chemokines produced from influenza-infected cells. In contrast to the rhinovirus that causes the common cold, influenza does cause tissue damage, so symptoms are not entirely due to the inflammatory response. This massive immune response might produce a life-threatening cytokine storm. https://reagents.creative-...
