Li-Meng Yan

Li-Meng Yan or Yan Limeng, is a Chinese ophthalmologist and virologist whose 2020 publications and interviews alleging that SARS-CoV-2 was made in a Chinese government laboratory have been widely disputed by the scientific community. Yan claimed in interviews that she became aware of person-to-person transmission of COVID-19 in late December 2019, and that she attempted to communicate the risks to her superiors in late December 2019 or early January 2020. She alleges that the Chinese government and the World Health Organization (WHO) knew about the person-to-person transmission of COVID-19 earlier than they reported or made public, and suppressed both her research and that of others.
