The flu is one of the most infectious diseases in the world. In the United States alone, it is estimated that anywhere from 5 to 20 percent of the US population contracts the flu every year. Common flu symptoms include fevers over 101°F, severe headaches, dry cough, joint pain, chills, and fatigue.
Generally, the flu is not a life-threatening disease. However, it does weaken the immune system, heightening the chances that more serious respiratory diseases, like pneumonia, will strike a person.
The flu can be largely avoided by practicing good health habits such as properly washing the hands with soap and water, refraining from touching the eyes, nose, and mouth with unwashed hands, and observing a healthy diet. However, the best way to prevent contracting the flu is to get vaccinated.
