It transmitted rapidly affecting more than 200 countries globally, so, the World Health Organization has declared it as a pan-demic. SARS-CoV-2 presently is a 7th amongst known coronaviruses that cause infection in people, after 229E and OC43 (earliest studied viruses in human patients suffering from a common cold). It has infected humans in all age groups, of all ethnicities, both males and females while spreading through communities at an alarming rate. Infected patients experience common cold-like symptoms along with raised temperature, non-productive coughing and difficulty to breathe.
