In addition, as we enter the winter season, there are concerns about the simultaneous epidemic of the new coronavirus infection and seasonal influenza this year.
So far, it has not been possible to say that the infection has spread from child to child in the school, but when the number of children treated as suspended due to infection in the home increases, the class will be closed. It is thought that there will also be a school in a situation where it is necessary.
In conjunction with the resumption of the new semester on September 1, 2022, the ward has decided to close classes according to the following criteria.

Regarding the closure of classes due to the new coronavirus infection, in order to prevent the spread of infection from the school to each home, the absence rate per class is 10%, and in small classes of less than 30 students, 3 or more absentees. As a standard, while the Omicron strain is the mainstream, as a characteristic of the Omicron strain, it is said that symptoms will appear in about 3 days after infection, so we will be closed for 5 days in principle.
Absence rate can be calculated by excluding those who do not come to school during the infectious period and students who are not related to the infection route. Depending on the situation, we can shorten or extend it and respond flexibly.
Below is the status of class closures at municipal elementary and junior high schools and kindergartens as of the update date.
