Academia Sinica noted that the new coronavirus has mutated from the early Wuhan No. 1 virus into a “type 6”, and the current British mutant virus is a subtype of the sixth type. (Schematic diagram) Image: New Head Housing Data Photo
A more contagious variant of the virus appeared in Wuhan pneumonia, causing the global epidemic to heat up. The Epidemic Central Command Center confirmed on the 30th that the first case of the Wuhan pneumonia virus variant was confirmed in Taiwan, and a man with a fever who returned to Taiwan from the United Kingdom brought the virus variant into the country. . Starting on New Year’s Day, China will “blockade the country for a month” to strengthen border control, and only one nationality can enter the country. Academia Sinica’s interdisciplinary research team found that the new coronavirus, which was first discovered in China, had mutated from early Wuhan virus number 1 to “type 6.” It has dominated the party since April of this year and currently represents 99% of the types of viruses circulating. And continue to mutate to produce new subtypes The current British variant of the virus is the sixth subtype.
According to a report by Public Health England (Public Health England), the British variant virus strain “VOC 202012/01” has 23 viral gene mutation points, which were first discovered in Kent, in the south-east of England, whose origin is still unknown. He is currently in London, the south and southeast of England. The British variant virus strain includes many mutation sites. According to GISAID data, there are 1,354 strains from the UK and 3 from Denmark. The first strains were found in the two countries on September 20 and November 9, respectively. The incidence was in the UK. It has been going up since the end of October 2020.
In response to the virus variant, the Academia Sinica team also announced the results of the virus variant research in the UK. According to data from the Global Influenza Data Initiative (GISAID), among more than 200,000 samples of virus gene sequences, the virus can be classified into six types, the sixth of which Since February and March of this year, the virus has it has exploded in several countries and has represented 99% of circulating viruses in just a few months. However, the British variant virus strain is not a new virus. It’s just that the sequence of the virus genome has changed. It appeared mainly in the UK and later became infected in other countries such as Denmark and Australia. It was also recently discovered in Germany, Singapore, and Hong Kong.
The team noted that if the virus makes a mistake during the replication process, it’s called a mutation. Most mutations have no effects or are negative. This mutation appears to be easier to spread, but the cause is unknown. It is not ruled out that it is the environment or the human body. Advance screening. There are 23 mutations in the genes of the British variant virus strain, of which 8 fall into the spike protein (the key to unlocking and attacking the human body), and among the 6 point unit mutations, there is 1 receptor on the key peak protein. The binding domain (the part of the virus that first contacts the surface of human cells), that is, the area of binding with human cells, is the key for the virus to enter the host cell.
The team mentioned that both the new coronavirus and the influenza virus are RNA viruses, which have high variability and are still lower than influenza viruses, so due to their characteristics, continuous mutation is inevitable. Viral mutations can occur randomly. Before defining the British variant virus strain mutation, it also appeared in different virus strains, but this time, many mutations appeared in the same virus strain and 8 of them fell on the peak protein. . At present, only its genetic sequence is known to have changed and its proliferative advantage in the UK is greater than that of other virus strains. The number of effective transmissions has also increased and the transmission speed may increase, but there are no reports showing that infected people will have more severe symptoms.
