BEIJING, Sept. 29 (Xinhua) -- China on Wednesday released a chronicle of international cooperation on the WHO-convened Global Study of Origins of SARS-CoV-2: China Part.

COVID-19 is the most serious pandemic and the biggest public health emergency the world has experienced in a century. The origins-tracing of SARS-CoV-2 aims to identify the zoonotic source of the virus and the route of introduction to the human population, including the possible role of intermediate hosts. The work is of vital importance to taking targeted interventions against infectious diseases and reducing the risk of similar events occurring. To produce a research report that can stand the test of history, a paramount principle that must be upheld is sticking to the spirit of science, adopting a science-based approach, and following the law of science.

The origins-tracing study is a complex and serious matter of science. To study the origins, transmission and evolution of COVID-19, which has raged across over 200 countries and regions, the global science community needs to work together so that science, solidarity and cooperation will prevail over ignorance, isolation and prejudice.

China has its share of COVID-19 prevention and control work. Yet, it has twice invited international experts to conduct origins-tracing studies. In a science-based, open, transparent and cooperative manner, China offered the necessary facilitation for WHO expert team’s work in Wuhan. With a sense of responsibility and urgency, the WHO-China joint team completed the China part of the global study of origins, giving a panoramic view of the work methods and major findings of origins-tracing study and offering suggestions for the next phase of global origins-tracing work.
