This review summarizes the outbreak of viruses causing the fatal disease, which is highly
pathogenic and efficiently transmitted from human to human. This first began in Wuhan, China, and
now turned into an epidemic situation worldwide. A novel coronavirus (2019-nCoV) or severe acute
respiratory syndrome coronavirus(SARS-CoV)-2 belongs to β-coronavirus genera originated in bats due
to highly identical genome which leads to bat coronavirus. This review highlights the study of Indian
Council of Medical Research, India, which determined the detection of pathogenic coronavirus in two
different species of Indian bats. Indian Council of Medical Research, India, has successfully isolated the
COVID-19 virus strain which was the first step towards diagnosis and the development of vaccines in
the country. The outbreaks of coronavirus received worldwide attention for overcoming the challenges
faced during this current pandemic as there is no clinically approved antiviral drug or vaccine available
yet. However, preventive measures and different treatments were taken to cope with this viral outbreak.
In response to this global outbreak, this review tries to explain the Virology, Epidemiology and pathogenesis,
and discusses the diagnosis and treatment strategies of COVID-19. This review emphasizes the
current update of COVID-19.
