Overview

The pharynx is often the first site of infection for many contagious diseases such as the common cold. This is because viruses and bacteria often settle in this part of the body after a person inhales dust or water vapor containing the microorganism. Infection can also arise when a person touches their nose or mouth after having touched an object shared with another person with the disease. The foreign invader reproduces rapidly after settling on the body tissue.
