What is the origin of COVID-19?

At present, there is no scientific basis to clarify the true origin of COVID-19.

On the afternoon of April 8, the State Council held a press conference on the traceability study of COVID-19 in China. Zhou Lei, a researcher at China Center for Disease Control and Prevention, said that in the first phase of joint research, we have reached a conclusion about the origin of COVID-19. In the report, we clearly put forward several hypothetical research results on the origin of COVID-19 epidemic.

In the report, we evaluated the possibility of human, animal and cross-species transmission, including the laboratory.

The conclusion is that the possibility of direct spillover of zoonotic diseases is "possible to extremely possible", and we think that the introduction through intermediate hosts is "extremely possible to extremely possible", the introduction through cold chain is "possible" and the introduction through laboratory is "extremely impossible".

The place where the epidemic was found is not equal to the origin of the epidemic.

Zhou Lei introduced that it is difficult to study the source of the virus. It's only been three years since the COVID-19 Conference, and we still have a long way to go. Many research results of disease traceability tell us that the place where the epidemic was found is not equal to the origin of the epidemic, but we should adhere to a scientific attitude.

More importantly, in order to trace back to the source of COVID-19, it is necessary for scientists all over the world to study together and carry out research work comprehensively and objectively.
