Japanese mutant virus from Brazil is also on the rise… “I can’t handle the inflow of a few people”

On the 10th, as the corona 19 mutant virus from Brazil was first confirmed in Japan on the 10th, an emergency in Japan took place.

The infectivity of this mutant virus is still unknown. However, in that the virus has a structure similar to that from the UK and South Africa, it is likely to be more infectious than the general Corona 19 virus.

According to the support report, the Japanese Ministry of Health, Labor and Welfare decided to report the virus to the International Health Organization (WHO) and provide relevant information to the Brazilian Ministry of Health.

As a new mutant virus was discovered in four Brazilian entrants on the 10th, the number of corona19 mutant virus infections in Japan, including those from the UK and South Asia, increased to 34. Of these, 27 were found at airport quarantine, but the remaining 7 were confirmed after entering the country, and the possibility that the mutant virus has already spread to local communities through them cannot be ruled out.

On the 10th, it was confirmed in Tokyo that three men and women in their twenties were infected with a mutant virus from the UK. After entering the UK, they had a dinner with a man in his 30s who was tested positive for Corona 19, and it is known that 10 people participated in the dinner at that time.

The UK mutant virus is up to 1.7 times more infectious than the existing virus. Mutations from South Africa are estimated to be more infectious than those from UK.

The Sankei Shimbun reported on the 11th, “It is not known exactly how many people have been infected with the mutant virus in Japan so far.” This is because it is not possible to determine whether a mutant virus has been infected with the COVID-19 test alone. In Japan, the National Institute of Infectious Diseases is conducting genome analysis of viruses detected at airport quarantine stations and domestically to identify mutant viruses, and so far, about 6% of the total infected have been tested.

On the 10th, Professor Yuichi Ino (Life Sciences) of the University of Tokyo University announced a research result that if a mutant virus is introduced into Japan, it can result in an explosive spread of infection after several months.

According to the Sankei Shimbun on the 11th, Professor Ino calculated the spread of the existing virus as 1 and the spread of the mutant virus as 1.7. As a result, the influx of a small number of mutant virus infections within 10 people led to unbearable results after 6 months. .

For example, when there are 300 people infected with the existing Corona 19 virus, and 10 people infected with the mutant virus enter the community, the number of new infected people a day after 4 months will be 1,000. After 6 months, it will increase to 2000, and at this point, the number of mutant virus infections will increase than the existing virus infections.

If 100 people infected with the mutant virus are introduced in a situation where there are 300 people infected with the existing virus, the number of confirmed cases will increase to 3,000 a day in 4 months, and more than half of the people infected with the mutant virus will. After 6 months, the number of infected people per day increases to about 13,000.

Professor Ino pointed out that based on this simulation, “it is necessary to perform more thorough airport quarantine in order not to introduce the mutant virus any more.” “Assuming that the mutant virus has already spread on the market, much stronger regulation is needed than now.”

Meanwhile, in Japan, there were 6098 new corona19 confirmed cases in one day on the 10th. In Tokyo, 1494 people were confirmed.
