Influenza (Flu)

Influenza, commonly referred to as “flu”, is a contagious disease caused by Influenza virus. Influenza virus is transmitted through breathing air that contains the infective virus. The viruses are present in the air in form of aerosols, which are fine solid particles or liquid droplets suspended in the air. The aerosols that contain Influenza virus are released into the air whenever a person coughs or sneezes. 

Influenza is common in winters and it can infect any age group.

The affected person may develop fever, cough, sore throat, headache, bodyache, and weakness. The infection usually resolves by itself within a week or two and even without treatment. It is a self-limiting condition. But in some cases, severe symptoms such as shortness of breath or high fever may occur due to associated conditions such as Pneumonia.
