Emerging Viruses Besides the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)

Abstract

The emergence of deadly viruses is one of the epitomes of major global health threats. Currently the world is going through the COVID-19 pandemic resulting in extreme morbidity and mortality, which is caused by the severe acute respiratory coronavirus 2 (SARS-CoV-2). Besides, SARS-CoV-2, recent global perturbation caused by the chikungunya virus (CHIKV) infection, dengue caused by dengue virus (DENV), zika virus (ZIKV) infection, etc. are worth being noted. Although an array of research on the genome sequences within spatial geographical locations, infectious components, viral transmissibility and dynamics, treatment strategies using in silico model, animal/cell culture, and patient trials of these emerging viruses is being conducted, the human population is still at risk of being exposed to the emerging and re-emerging viral infections posing a most dreadful threat to the global public health. Besides the genomic characterization and the proteomic studies for drug repurposing or repositioning as well as the possible candidate vaccine development, the general awareness among the mass public about the preventive care against these emerging viruses is also an important concern. Lots of works have been reported on SARS-CoV-2 since its commencement on December 2019. Besides the elucidation of the respiratory viruses, present review briefly pointed on the viruses from Flaviviridae family, Paramyxoviridae family, Filoviridae family and Bunyaviridae family.
