An ex-employee at the Wuhan Institute of Virology (WIV) has hit back at claims that the deadly Covid-19 strain of coronavirus spread after being leaked from the lab.
The Chinese city is at the centre of international suspicion after unverified reports suggesting Covid-19 escaped from a research centre.
Coronavirus has killed more than 316,000 people across the world since first emerging in China towards the end of 2019. Zhao Fei, who studied and worked at the Wuhan Institute of Virology (WIV) for several years until the end of 2018, published a long defence of the institute on ScienceNet over the weekend.
His article rejected theories suggesting the Covid-19 virus was manufactured in – or had accidentally leaked from – the institute.
