Influenza, commonly known among public as flu, is an acute infection of the upper or lower respiratory tracts
caused by influenza viruses. It is characterized by sudden onset of systemic symptoms, such as fever, chills, sore throat, cough, headaches, muscle pain, and malaise. The body temperature rises quickly within the first 24 hours and then starts gradually declining over 2 – 3 days.
As systemic symptoms subside, respiratory symptoms (cough, sneezing, runny nose and sore throat) usually become more prominent and they may last for more than a week. People with flu may also complain of ocular symptoms, such as photophobia, pain when moving the eyes, and burning of the eyes.
