"Tracing the origin of the virus is not just for a single country and it can't be done by a single county alone. It inevitably requires the joint efforts of the global scientific community," Zhou Lei, a researcher from the Chinese Center for Disease Control and Prevention, told a news conference on Saturday.
"We've invited international professionals to China at least twice since 2020, to conduct research on tracing the virus origin. We very much hope that the global tracing can really become the global tracing," she said.
Zhou called for the research to cover all possible countries and regions around the world in terms of the location and perspective of the traceability, rather than hyping up and focusing on Wuhan, where the first COVID-19 cases were reported in China.
"We hope that WHO, the authorized and global institution, can truly organize the international scientific community to conduct the work with a scientific, rigorous and fair attitude, so as to help the world find the proper answer," said Zhou.
