The Ministry of Health, Labor and Welfare has reduced the waiting period at home and accommodation required for close contacts of Omicron strains from the current 14 days to 10 days.


We will continue to urgently collect and analyze information on the characteristics of Omicron strains and consider revising the treatment of infected and close contacts as necessary.

With the replacement of Omicron stocks nationwide, the Ministry of Health, Labor and Welfare has reduced the waiting period at accommodations and homes required of close contacts from the current 14 days to 10 days in order to maintain social functions on the 14th. I notified the local government to shorten it.



In addition, so-called "essential workers" such as medical staff, police and fire departments can cancel the waiting if the PCR test conducted on the 6th day from the day of the last contact with the infected person is negative.



Regarding this response, the Ministry of Health, Labor and Welfare explains that the incubation period of Omicron strains is shorter than that of conventional viruses, so even if the waiting period is shortened, the risk of developing the disease does not change.



The Ministry of Health, Labor and Welfare will continue to rush to collect and analyze information on the characteristics of Omicron strains, and if necessary, consider reviewing the treatment of infected persons and close contacts, and even if the spread of infection continues, it will function as a society. I want to be able to maintain.
