Abstract

In the present globalised world, outbreaks of emerging or re-emerging novel viruses have exerted the greatest toll on human health. The ongoing health crisis due to the novel SARS-CoV-2 disease (COVID-19) has brought the world to a standstill. Its actual source of origin and mechanism of high transmission and aggressive pathogenesis still remain poorly understood. SARS-CoV not only causes severe respiratory disease but also manifests in other vital organs, notably the digestive tract and liver. Nonetheless, previous experiences with the 2002-3 SARS-CoV and 2012-13 MERS-CoV outbreaks have helped understanding the virus pathobiology to some extent.

A comparative sequence analysis of SARS-CoV-2 with human CoV (SARS-/MERS-CoV) and mammalian SARS-like CoV (bat-/civet-/pangolin-SL-CoV) has revealed its very close similarity (~96%) with bat-SL-CoV. Because the virus has zoonotic origin and is newly introduced, humans lack natural immunity against it. Of the novel and unique mutations observed in SARS-CoV-2, the most important ones have been found in the cellular ACE2 receptor binding-motif as well as generation of a furin-like cleavage site in its ‘Spike’ protein. These genetic features strongly suggest the adaptive evolution, enhanced infectivity and disease severity of COVID-19 in humans.

While hundreds of treatment and intervention candidates are undergoing clinical trials, the anti-Ebola drug remdesivir has been recently approved as ‘emergency drug’ and the mRNA vaccine is ready to enter phase-2 trial.
