Cold and Flu
A Answers (2)
Usually, the first effect of influenza (flu) on the body is a fever with chills and muscle aches. You may also have a feeling of general weakness, fatigue, and a headache. Remember, influenza 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. Sometimes influenza may lead to pneumonia, which can be serious.
