A Chinese virologist who alleges the coronavirus was cooked up in a military lab has published a report which she claims backs up her theory.
Li-Meng Yan, who alleges to be a former researcher at the Hong Kong School of Public Health, says the virus was built by merging the genetic material of two bat coronaviruses.
She claims its spike protein – a structure on the surface of the virus which it uses to bind with cells – was edited to make it easier for the virus to latch on to human cells.
