Flu
Influenza, commonly referred to as the flu, is a disease of the lungs and upper airways caused by infection with a flu virus. The most common symptoms of the disease are chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort.
There is currently a higher demand for the anti-viral Tamiflu and for information about the flu due to the current swine flu outbreak (which refers to the spread of a new strain of H1N1 influenza virus that was first detected in humans by public health agencies in Mexico, March 2009).
