Abstract
In late 2019, following the emergence of a β-originated SARS-CoV-2, phylogenetic and evolutionary approaches have been demonstrated to strengthen the diagnostic and prophylactic stratagem of COVID-19 at an unprecedented level. Despite its clinical prominence, the SARS-CoV-2 gene set remains largely irrefutable by impeding the dissection of COVID-19 biology. However, many pieces of molecular and serological evidence have predicted that SARS-CoV-2 related viruses carry their roots from bats and pangolins of South East Asia. Analysis of viral genome predicts that point mutations at a rate of 10[SUP]-4[/SUP] nucleotides per base in the receptor-binding domain allow the emergence of new SARS-CoV-2 genomic variants at regular intervals. Research in the evolution of molecular pathways involved in emergence of pandemic is critical for the development of therapeutics and vaccines as well as the prevention of future zoonosis. By determining the phyletic lineages of the SARS-CoV-2 genomic variants and those of the conserved regions in the accessory and spike proteins of all the SARS-related coronaviruses, a universal vaccine against all human coronaviruses could be formulated which would revolutionize the field of medicine. This review highlighted the current development and future prospects of antiviral drugs, inhibitors, mesenchymal stem cells, passive immunization, targeted immune therapy and CRISPR-Cas-based prophylactic and therapeutic strategies against SARS-CoV-2. However, further investigations on Covid-19 pathogenesis is required for the successful fabrication of successful antivirals.
