Abstract
In December 2019, a new species of coronavirus (SARS-CoV-2) was identified in a number of patients presenting with pneumonias of unknown aetiology in WuHan Province, China. Early epidemiological indications were of a zoonotic origin: many of the initial patients confirmed contact with a local wet market and the genomic sequencing showed similar characteristics with coronaviruses known to be carried by bats. The theory of subsequent human to human transmission became evident once global epidemiological reporting of COVID infection was established. Confirmation of the origins of infections caused by SARS-CoV-2 was enabled by the early sharing of the initial genomic sequence by China in January 2020 and since developed collaboratively on a globally accessible database, supported by the World Health Organization (https://tinyurl.com/rj32fp3).
