I. Introduction
In a human body lungs are important parts of respiratory system responsible for gaseous exchange. Maintaining the lung health is important for the constant vitality of life. One of the major respiratory disorders involving the lungs is pneumonia. Pneumonia leads to the accumulation of fluid within the air spaces of the lungs, resulting in breathing difficulties for the infected individuals. The major causes of pneumonia are virus, fungus and bacteria [1]. After the outbreak of COVID-19 focus is shifting towards virus as microorganism causing diseases. These viruses have the ability to mutate and adapt frequently which poses significant challenges to their effective treatment and prevention [2].
