Science’s COVID-19 reporting is supported by the Pulitzer Center.

China is facing growing pressure from national governments and international organizations to open its doors to an independent, international investigation into the origins of the novel coronavirus causing the current COVID-19 pandemic, as well as into the nation’s early response to the outbreak. So far, however, the Chinese government has given no public sign it is interested in cooperating. Its silence, and signs that China is stifling origins research by its own scientists, have fueled theories that the virus accidently leaked from a lab there.
