A Chinese virologist who has alleged that COVID-19 was human-made in a lab in China released a report on Monday that she says backs up her explosive claim.

Dr. Li-Meng Yan, a former researcher at the Hong Kong School of Public Health, posted a paper on the open-access repository website Zenote, that she claims shows how SARS-CoV-2 could be “conveniently created” in a laboratory setting in six months.

The paper, co-authored with two others, is titled “Unusual Features of the SARS-CoV-2 Genome Suggesting Sophisticated Laboratory Modification Rather Than Natural Evolution and Delineation of Its Probable Synthetic Route.”
