a short answer a virus where you experience sneezing coughing fever muscle aches ect. but no medicines can cure one the immune system must fight it off on its own medications can ease symptoms so you dont have a fever you dont cough as much dont sneeze as much ect. but all you really have to do is get lots of sleep eat enough food to keep you going at least take a fever reducing medication like advil motrin ect ive found that even taking allergy medicine helps me feel a little more human to the best of luck?
