The common cold is a viral infection that affects the upper respiratory tract. The primary signs of the common cold are fairly obvious: a stuffy or runny nose, sneezing, and pharyngitis. Due to the widespread nature of this illness, most people recognize these early symptoms very quickly.
When the virus overpowers the system and enters the body, it causes an infection. It attacks the mucosa, the body’s first line of defense. As soon as this virus enters a cell, it takes control of the cell’s machinery and produces more viruses. Often, this is how you fall victim to a severe virus. It is even easy for these viruses to spread from one person to another or from one surface to another. Most of these viruses can even survive on surfaces for several hours or even days.
