Severe acute respiratory infection remains one of the leading causes of mortality around the world. The recent pandemic caused by an RNA virus that belongs to the family of CORONA (Latin Crown, from the structure of the virus under electron microscope) virus is a challenge for both developed and underdeveloped nations. The new CORONA virus identified as the cause of the acute respiratory disease in humans since the end of December 2019(2019-nCoV), later labeled as SARS-CoV2 by World Health Organization is a different strain of CORONA virus from SARS and MERS CORONA viruses. The difference is not limited to genetic make-up only but also in the clinical presentations, case fatality and the rate of spread across the globe. The disease caused by this virus is known as COVID-19.
