Full Answer

According to the New York State Department of Health, the influenza virus is spread through the coughs and sneezes of an infected person. If individuals swallow or breathe in these infected droplets, they may become infected by the virus. Additionally, some people may contract the illness by touching an inanimate object that has the virus on it before then touching their eyes, nose or mouth.

The primary symptoms of the flu include a fever, sore throat, cough, nasal congestion, headaches, body aches and fatigue, according to the New York State Department of Health. As explained by HowStuffWorks, some of these symptoms, such as a sore throat, are caused by the virus itself. Conversely, the fatigue and fever are symptoms produced by the body as it attempts to fight off the infection.

According to the New York State Department of Health, approximately 200,000 people are hospitalized each year in the United States due to influenza. Approximately 23,000 of these people, primarily those over the age of 65, die each year.
