The National Institute of Infectious Diseases has summarized the evaluation of the mutant virus of the new coronavirus, and said that it is almost certain that the mutant virus confirmed in India is equal to or higher than the infectivity of the mutant virus so far, at the water's edge or in Japan. I said that it was necessary to take measures.
This month, the National Institute of Infectious Diseases published a summary of past evaluations of domestic mutant viruses.
According to this, the "Theta strain" of the mutant virus confirmed in the Philippines, which was designated as a "mutant virus of concern" in Japan in April, has not been expanded, so the classification has been lowered. It means that it has been made a "notable mutant virus".
Also, in Japan, the three types of mutant viruses confirmed in India have been collectively referred to as "mutant viruses of concern", but only the "delta strain", of which the number of infected people is increasing, should be "concerned". I decided to make it a "mutant virus".
And, as for the "Delta strain" confirmed in India, it is almost certain that the infectivity is equal to or higher than that of the mutant virus confirmed in the United Kingdom, and it is said that the chances of contact will increase and the infection control will be loosened. He said there was a greater risk of epidemics than ever before.
On top of that, although the risk of entering from overseas is suppressed to a certain extent by border measures such as immigration restrictions for mutant viruses, it is necessary to continue to take appropriate and agile measures in Japan, saying that it cannot be completely prevented. I pointed out.
