Tochigi Prefecture announced on the 30th that it was confirmed that a man in his 40s who had returned from overseas and was waiting at his home in the prefecture was infected with the new coronavirus mutant virus "Omicron strain".
This is the first time that infection with Omicron strain has been confirmed in Tochigi prefecture.
According to Tochigi Prefecture, it was a man in his 40s who lived in the prefecture that was confirmed to be infected with the Omicron strain.
The man returned from the United States this month and was waiting at his home in the prefecture, but found that a man infected with the Omicron strain was on the same plane as the man.
For this reason, when the prefecture's Health and Environment Center conducted a genome analysis as a close contact, infection with the Omicron strain was confirmed on the 30th.
The man has no symptoms and is currently admitted to a hospital in the prefecture.
Since there are no close contacts other than the male family, the prefecture is also investigating whether the family is infected with the Omicron strain.
Governor Tomikazu Fukuda of Tochigi Prefecture said, "This time it is not a community-acquired infection, but given that the number of community-acquired Omicron strains is increasing in Japan and the number of infected people in the prefecture is increasing, the infection spreads again. I am aware that it may have started. "
