Did you know that there are more than 200 viruses that cause the common cold? Meanwhile, only three known viruses are behind the flu?
Cold and influenza viruses are common contagious illnesses that affect millions every year. Typically, the height of flu season is from October through March, and the cold season is between August and April.
As you can see, some of these months overlap.
So, does that mean you can only be sick with one virus at a time? Or, is it really possible to get sick with both a cold and flu virus simultaneously?
