Abstract
Introduction
Very recently, a novel beta‐CoVs coronavirus (2019‐nCoV) originating from the province of Wuhan, China, has been causally linked to severe respiratory infections in humans.[1] As of today 28/03/2020, there are 517678 confirmed cases of covid-19 in the world, involving 202 countries and resulting in almost 26,495 deaths worldwide[2]. India has 819 positive cases resulting in 19 deaths. This article will give a panorama view of this new emerging infection. This corona virus infection is rapidly evolving and much of the details and research is required for the same.
History
Coronaviridae (CoVs) are the largest known single‐stranded RNA viruses. Coronaviruses are members of the subfamily Coronavirinae in the family Coronaviridae and the order Nidovirales (International Committee on Taxonomy of Viruses).[3] This subfamily consists of four genera-
- Alpha‐CoVs- responsible for gastrointes-tinal disorders in human, dogs, pigs, and cats;
- Beta‐CoVs- including the Bat coronavirus (BCoV), the human severe acute respiratory syndrome (SARS) virus and the Middle Eastern respiratory syndrome (MERS) virus
- Gamma‐CoVs- infecting birds
- Delta CoVs- infecting birds.[1,3]
