How widespread is the highly infectious mutated coronavirus in each region?


I understand the current situation.


In Osaka, Kyoto, and Hyogo, where a state of emergency has been declared, more than 80% have been replaced by conventional viruses, and more than half in Tokyo have been replaced by conventional viruses, and the replacement is progressing rapidly nationwide.

"N501Y" mutation In the area of ​​the state of emergency ...

Motoi Suzuki, director of the National Institute of Infectious Diseases Epidemiology Center for Infectious Diseases, said at an expert meeting held on the night of the 27th that a virus with a highly infectious "N501Y" mutation was detected by a private testing company. The data that estimated the spread of each region is shown.

This is the result of the area where the state of emergency is declared.

<Osaka Hyogo Kyoto> Over 80% by the end of this month

The proportion of mutant virus was about 20% at the beginning of March, but it was about 70% at the beginning of this month, and the infection of the mutant virus spread the fastest in Japan, and the replacement progressed rapidly.

After that, it is estimated that it will exceed 80% by the end of this month.

<Tokyo> About 80% at the beginning of next month

The proportion of mutant viruses increased later than in Kansai, and it is estimated that it was about 20% at the beginning of this month, more than half at the end of this month, and about 80% at the beginning of next month.

"Rapid replacement" nationwide except Tohoku

The proportion of viruses with the "N501Y" mutation is increasing in other regions as well, and the National Institute of Infectious Diseases says that it is rapidly being replaced nationwide except in the Tohoku region.

On the other hand, recently, especially in Osaka Prefecture, the speed of replacement tends to slow down, and it is said that it has reached a "peaking out" state, and the reason for this


is that the speed of replacement with mutant viruses is increasing while the number of people is decreasing. It is said that it may be changing and that it may


not be replaced 100% against other strains of virus.

Director Takaji Wakita, National Institute of Infectious Diseases


"The number of effective reproductions of the mutant virus that is spreading now is 1.32 times the national average, which indicates that it is easier to infect than conventional viruses. However, the infectivity varies depending on the region. There was a difference, with a difference between approximately 1.21 and 1.68 times. "

"N501Y" mutation In areas with many infected people ...

In other regions, the proportion of new coronaviruses with the highly infectious "N501Y" mutation is increasing.

The results estimated by the National Institute of Infectious Diseases for other regions as of the 26th of this month are as follows.

<Tokyo Kanagawa Saitama Chiba 1 metropolitan area 3 prefectures> About 80% at the beginning of next month

It was about 20% at the beginning of this month, but it has been replaced rapidly by more than half by the end of this month, and it is estimated that it will be about 80% by the beginning of next month.

<Aichi> Over 70% at the beginning of next month

The replacement is progressing rapidly.

It is estimated that it will be close to half at the beginning of this month and more than 70% at the beginning of next month.

<Fukuoka> More than 80% later this month

It was rarely seen until the middle of last month, but it is estimated that it will be 20% to 30% in the beginning of this month and more than 80% in the end of this month.

<Okinawa> More than 80% later this month

It was low until the beginning of last month, but it has expanded rapidly since the beginning of this month, and it is estimated that it will be about half in the middle of this month and more than 80% in the end of this month.

<Tohoku of Miyagi Yamagata Fukushima>

The replacement of the "N501Y" with a mutated virus has not yet been seen significantly.

"N501Y" mutation in Tokyo and 44.4% of private inspection agencies

In Tokyo, a new type of coronavirus with a mutation of "N501Y" was found in more than 40% of the tests conducted in Tokyo during the week up to 18th of this month, and it was found that it increased by more than 14 points compared to the previous week. I did.



In Tokyo, the Tokyo Metropolitan Institute of Health and Safety and private laboratories are inspecting for viruses with the "N501Y" mutation.

As a result of examining 1562 samples, which is close to 40% of the newly confirmed positives in Tokyo during the week up to the 18th of this month, viruses with the "N501Y" mutation were found in 694 cases, which is 44.4%.

This is an increase of 14.4 points compared to the week leading up to the 11th.

Approximately 60% in Tokyo Metropolitan Institute of Health and Safety analysis

In addition, as a result of analyzing the samples collected at the "Health and Safety Research Center" in Tokyo, 59.6% of the viruses had the "N501Y" mutation in the week leading up to the 25th of this month.


Almost doubled compared to the previous week, experts said, "The N501Y is completely gaining an edge. Given the threat of the N501Y, we need to stay vigilant and keep an eye on the trends. ".

Tokyo Almost all mutant viruses are more than 1,700 positives two weeks later

It was also estimated that if almost all of them were replaced with the mutant virus, there would be 1742 new positives and 4450 inpatients in two weeks.

Variant virus Over 10,000 infected people in Japan

Regarding the mutated coronavirus, the Ministry of Health, Labor and Welfare has announced that more than 10,000 people have been confirmed infected in Japan.

Municipalities across the country are extracting samples from some of the new coronavirus-infected individuals to see if they are infected with the mutant virus found in the United Kingdom, Brazil, South Africa, and the Philippines.



According to the Ministry of Health, Labor and Welfare, the local government reported that the mutant virus was detected in a total of 10,102 people nationwide from December to April 27, last year.

In addition, the total number of infected people confirmed in the week up to the 27th was 4,186 in 43 prefectures, which is about 1.8 times the number in the previous week (2352).



In addition, as a result of analyzing the genes of more than 2,200 samples infected with the mutant virus so far, the first virus found in the United Kingdom was detected in 96% of people.
