Still, a lot of illnesses and symptoms get blamed on the flu, especially during the winter, that likely are caused by other viral illnesses or other conditions.
If you consider that only 5 to 20 percent of people get the flu each year, and they typically get it just once, then every cough, cold, ache, pain, and fever, can't be caused by the flu.
