Understanding Influenza

Course overview

Influenza, also called the flu, is one of the most common infectious diseases. It is common because of the ease that it may be transmitted from one person to another. There are specific signs and symptoms of an influenza infection. Influenza is distinctively different from a cold. An influenza patient will develop a cough, fever, malaise, and muscle aches but within two to five days the immune system controls the infection, the signs and symptoms abate, and there are no long-term consequences. The amount and infectious level of influenza virus shed into air and passed on between hand contact or contaminated surfaces is not fully known. Nonetheless, well known prevention and health guidelines and treatment exist that both patients, family and healthcare workers should follow.
