Extract
The Coronavirus (COVID-19) epidemic, which was first reported in December 2019 in Wuhan, China, has caused 80 904 confirmed cases as of 9 March 2020, with 28 673 cases being reported outside of China. It has been declared a pandemic by the World Health Organization which exhibited human-to-human transmissibility and spread rapidly across countries [1]. Although Chinese government has taken various measures to control city-to-city transmission (e.g. shutting down cities, extending holidays) and many countries have implemented measures such as airport screening and testing of patients who have reported symptoms, the number of cases still increases quickly throughout the world.
