The term “common cold” is a bit of a misnomer
Common implies that there’s a single ordinary pathogen to blame for your runny nose, coughing, and mild fatigue. Actually, there’s a huge array of viruses—more than 200 of them—that induce colds, each with its own means of evading your body’s defenses. For this reason alone, it’s unlikely that a catchall “cure for the common cold” will ever be found. These are crazy cold symptoms you probably never knew about.
