Corona virus disease-2019 (covid-19) pandemic: an eerie challenge to the global community

Named after the crown-like spikes on their surfaces, it is established that coronaviruses (CoVs) constitute a large group of viruses, most of which circulate among animals such as pigs, camels, bats and cats (1). The history of human coronaviruses began in 1965, and we know that new coronaviruses appear to emerge periodically in humans, primarily due to the high prevalence and wide distribution of these viruses, the large genetic diversity and frequent recombination of their genomes, and the increase of human-animal interface activities (2). It is fascinating to see that ongoing research using serologic techniques has resulted in a considerable amount of information regarding the epidemiology of the human coronaviruses. We recognize that the enormous infusion of energy and activity around the expanding field of veterinary virology has deepened our knowledge about the virology and pathogenesis of coronaviruses (3).
