A Honor Society of Nursing (STTI) answered. Usually, the first effect of influenza on the body is a fever with chills and muscle aches. You may also have a fever, fatigue and a headache. Remember, the flu is caused by a group of viruses that infect the respiratory system. As a result, effects on the body often focus on the throat, nose, and lungs. The nose may become congested or runny, the throat may become sore, and a cough may move from dry to wet as the virus runs its course. The common cold primarily produces sneezing, nasal congestion, runny nose, and a sore throat.
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.
