COVID-19: A bitter truth

Abstract

The COVID-19 (Coronavirus Disease-19) is extremely contagious and quickly spreadable pathogenic viral infection caused by SARS-CoV- 2, a virus belongs to coronavirus family member. It was appeared abruptly in Wuhan, China; transmitted possibly from bat to human followed by human to human and now becomes pandemic. The intermediate stage of transmission is not known but becomes a global challenge to stop the spread of virus. The best way to avoid the chain of viral spread is suggested as isolation. Though, mutagenic strains of this virus has been observed, the genome of virus has been sequenced that helps in development of viral diagnosis kit. Vaccines has been developed in the vast genomic era and now the world is moving towards direct human vaccine trial. The sensitivity of diagnostic kits, development of antiviral drugs and vaccines can save the life. This review is focused on overall knowledge of viral origin, their genetics, structure, diagnosis, precautions and possible therapy currently developed or under developmental progress by scientist.
