 Beijing new coronavirus is the most similar to Czech? Who: the origin cannot be determined temporarily


Novel coronavirus National Science and technology resource service system released three data in China on June 18th night, the genome data of Beijing confirmed cases (NMDC60013902-01, NMDC60013903-02) and environmental samples genomic sequence data (NMDC60013903-03), all of which were samples of recent outbreak in Beijing.

The three samples were collected on June 11, 2020. It is rapidly sequenced by CDCs Institute of viral disease prevention and control and shared by gisaid.

Recently, the sequence of the virus samples from Beijing outbreak falls in the same evolutionary cluster, many of which are from Europe, which is very different from the gene sequence of the three input viruses from the previous sampling.

In the evolutionary framework of the global coronavirus, the new coronavirus sequences from the Czech Republic, Taiwan, Greece and Portugal are the closest to the three new coronavirus sequences from Beijing.

According to the regional distribution, in the evolutionary framework of Asian coronavirus, the sequence of Beijing is close to that of Czech Republic, Taiwan, Denmark, Colombia, Israel and Austria.

In the evolutionary framework of the European coronavirus, the sequence of Beijing is very close to that of many European countries such as Czech Republic and Denmark, among which only one mutation is different from that of Portugal and Sweden.

Therefore, from the perspective of gene sequence analysis, the newly transmitted coronavirus in Beijing is related to the virus prevalent in Europe. However, because of its similarity with the sequence of many countries / regions, it is impossible to determine where it originated and when it was introduced into Beijing.

Novel coronavirus pneumonia, Michael Ryan, director of health emergency project at the World Health Organization, also said that there are different strains of virus spreading in Beijing, and it does not mean that the disease is from Europe. It is very likely that the virus is imported from outside of Beijing. Now it is important to determine the time and the transmission chain of the virus. Who is glad to see the high strength taken by the Beijing. Degree of investigation to ensure that the source of aggregated sexual transmission is found.
