Preventing the spread of corona infection "It is important for people to meet only within the community"

In order to stop the spread of the new coronavirus, Prime Minister Suga

called for cooperation, such as refraining from meetings as much as possible at the

press conference

.

Professor Yukio Osawa of the University of Tokyo, who is studying countermeasures by analysis using AI in a government subcommittee, points out that it is important to limit the people who meet to people who usually meet, such as homes, schools, and workplaces. ..

Professor Osawa focused on the nature of human beings trying to gather in a specific place and expanding relationships at the place where they gathered, and simulated the spread of infection using AI.

As a result, if you limit the people you meet to within the normal community such as home, school, and work, the risk of spreading the infection is low even if you eat or go out together, but with people outside the normal community. The more contacts there are, the higher the risk, and when the number exceeds the number of people in the normal community, the risk increases at once.

In addition, even if people refrain from going out and the spread of the infection begins to subside, if the number of contacts outside the community increases at an early stage, it will be a factor to spread it again.

Professor Osawa said, "Even after the period when self-restraint is being called for, contact with people who do not usually meet increases the risk of spreading the infection, so it is important to keep the people who meet for a while as much as possible in the community." I'm talking to you.
