A virus causes RSV infection. Like a cold virus, RSV attacks your nose, eyes, throat, and lungs. It spreads like a cold too, when you cough, sneeze, or share food or drinks.
There are many kinds of RSV, so your body never becomes immune to it. You can get it again and again throughout your life, sometimes during the same season.
