Corona viruses are the group of virus which is a group of viruses that have a crown like appearances when viewed in under the electronic microscope. They belong to the Coronaviridiae family. Corona virus causes the Severe Acute Respiratory Syndrome (SARS) [4]. They are commonly known to cause the respiratory disease in human being. Some time they also caused the gastrointestinal disease in different farm animals. They contain +ve single standard enveloped RNA as their genetic material. The genome of corona virus is the largest among the viruses (27-32 in length). Large, roughly spherical, enveloped particles with a nuleocapsids and large, petal like spike 20nm long, protruding from the membrane appearing as the crown [1]. These viruses are host or tissue specific based on the receptor specificity of their spike or S protein. It is an enveloped viruses and the envelope is made up of glycoprotein.
