More than 200 different types of viruses are known to cause the common cold, with rhinovirus causing approximately 10%-40% of all adult colds. Other commonly implicated viruses include coronavirus, adenovirus, respiratory syncytial virus, and parainfluenza virus.
Some of the symptoms of a cold are caused by the actions of the virus. For example, destruction of cells lining the respiratory tract or throat can cause sore throat, cough, and runny nose. Other symptoms are caused by the body's immune reaction to the virus. When the body recognizes the viruses as foreign, immune cells release interferons and leukotrienes, which help mobilize the body's defenses, but also cause fever, aches, and fatigue. Adults average two to five colds a year.
