The Coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection caused by severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2), which emerged in Wuhan, China and spread around the world. As of 19 June 2020 data from the World Health Organization (WHO) have shown that more than 8457305 confirmed cases have been identified in more than 200 countries, with the number of cases cutting across all continents. On 30th January 2020, the WHO declared COVID-19 as the sixth public health emergency of international concern. Genomic analysis revealed that SARS-CoV-2 is phylogenetically related to severe acute respiratory syndrome-like (SARS-like) bat viruses; therefore, bats could be the possible primary reservoir. The intermediate source of origin and transfer to humans is not known, however, the rapid human-to-human transfer has been confirmed widely via droplets or direct contact, and infection has been estimated to have mean incubation period of 6.4 days. Currently, controlling infection to prevent the spread of SARS-CoV-2 is the primary intervention being used. However, public health authorities should keep monitoring the situation closely, as the more we can learn about this novel virus and its associated outbreak, the better we can respond.
