About Seasonal Influenza (Flu)

Influenza, also known as the flu, is a contagious disease caused by the influenza virus. It attacks the respiratory tract (nose, throat, and lungs) of humans. The flu is different from a cold or other respiratory infection (bronchitis).

Management of Students or Faculty Exposed to Influenza

Watch for fever (take temperature once a day) and respiratory symptoms for 2-3 days following exposure.

If symptoms develop, rest and drink plenty of liquids. Avoid alcohol and tobacco. Take medications to relieve the symptoms of flu, but avoid aspirin.
