An update in 2018 said that the scientific teams – who published many of their findings in international journals – had found four new pathogens and ten new bacteria while ‚more than 1,640 new viruses were discovered using metagenomics technology‘. Such research is based on extraction of genetic material from samples such as those collected by Prof Shi from bat faeces and blood in the cave networks of southern China.
Such extensive sampling led to Prof Shi‘s rapid revelation last year of RaTG13, the closest known relative to the new strain of coronavirus that causes Covid.
It was stored at the Wuhan lab, the biggest repository of bat coronaviruses in Asia.
