The flu can spread easily and unless your flu shot is up-to-date, you are vulnerable to catching the virus.The influenza virus can spread through the air and when infected droplets are inhaled, the virus can quickly multiply in the body. If there aren’t enough antibodies to fight it, flu symptoms will begin to manifest.
