165438+ 10, at the routine press conference on COVID-19 epidemic held by the World Health Organization, Michael? Ryan said: WHO has reached an understanding with countries all over the world and will join hands with scientists all over the world to trace the origin of COVID-19. The COVID-19 epidemic has been raging around the world for a long time, but it has not been well controlled. It is very important to find the source of COVID-19 and develop vaccines. Why is traceability so important? Because the source of COVID-19 has not been found, it is impossible to carry out scientific prevention and control according to its characteristics, which affects the deployment of the next epidemic prevention work.

At the beginning of the COVID-19 outbreak, world-renowned scientific researchers proved that COVID-19 came from wild animals. According to research, the host of COVID-19 is bat, and pangolin is the potential host of COVID-19. With the research of researchers, they said that the specific virus source of the COVID-19 epidemic has yet to be determined. According to research data, COVID-19 has the ability of evolution. If we can't find out the source of the virus as soon as possible, the future research will be much more difficult. According to the case, COVID-19 has strong interpersonal communication skills. There is a great difference between the current cases and the original cases, which means that with the continuous evolution of the virus, the transmission route of the virus has changed, and the conditions for human illness will also change.

China is the first country to report the epidemic, but the earliest reported cases are not necessarily the source of the virus. 20 19, 12, 1, the first case of COVID-19 was discovered in China. Considering the latent time of the virus in human body, it is inferred that the patient was infected with the virus at 1 1. In view of this, many countries in the world blame China for the epidemic, or even call it? China virus? . Imposing trumped-up charges on China will affect China's image as a great power.

Now, the medical journal International Journal of Antimicrobials shows that at the end of 20 19 and 12, cases were also found in other countries. This case has nothing to do with China, and it can even be said that patients first appeared in other countries. We can't speculate subjectively, we should believe in science and let scientists reveal the answer to the source of the virus.
