COVID-19 is an infectious disease linked to Severe Acute Respiratory Syndrome (SARS) disease that spreads primarily through contact with an infected person when they cough or sneeze (Sharma et al., 2020). This virus causes a respiratory illness with symptoms such as a cough, cold, fever, dehydration, souring, breathlessness, and potential loss of taste or smell (Bakar & Rosbi, 2020) which was first reported in Wuhan Province of China in December 2019 and later it spread rapidly worldwide (Nishiura H et al., 2020). A report by the World Health Organization (2020) the total confirmed cases of COVID-19 worldwide are 48.7 million cases with 1.23 million deaths as of 1st November 2020. This virus has diverse impacts on business, education, communication, health, and so on. People with weak immune systems or heart and lung disease are at higher risk of being infected (Kumar, 2020) including old age persons, children, and patients with a pre-existing clinical history like diabetes, cancer, respiratory disorders, obesity, lung disease, etc (Srivastava et al., 2020).
