Three scientists who fell sick with COVID-like symptoms in November 2019 are suspected of being patient zero of the coronavirus pandemic, according to Sky News host Sharri Markson.
Ben Hu, Yu Ping and Yan Zhu were employed by the Wuhan Institute of Virology and experimenting with RaTG13, the virus which has the closest genetic sequencing to COVID-19.
Ms Markson is joined by ANU Health and Medicine Professor Colin Butler to discuss this major revelation and how these scientists originally became infected.
