KOFU -- A total of six staff and customers at a restaurant that had received certification for its measures to prevent COVID-19 infections have been confirmed infected with the virus, the Yamanashi Prefectural Government announced on April 20.
Apart from information that the restaurant is in Yamanashi Prefecture's eastern Fuji region, the prefecture did not disclose any details including the name of the eatery and the gender and age of the patients, as it could lead to personal identification and reputational damage.
Some of the six were found to have mutant strains, and the prefectural government is investigating what caused the chain of infections. According to the prefectural government's Yamanashi Green Zone (GZ) Certification promotion division and others, the cluster was found while investigating the behavioral history of the six people from April 18. More than 10 people, including their close contacts and family members living with them, have since received polymerase chain reaction (PCR) tests.
On the morning of April 20, prefectural officials conducted an on-site inspection of the restaurant. Although they confirmed that the ventilation and seating arrangements were in line with certification standards, they are continuing to ask whether there were any problems with the diligence in wearing masks and the distance between customers.
The restaurant has been closed since April 18, and the prefectural government has temporarily excluded it from the GZ certification website. The prefectural government also indicated that it may review the certification criteria in the future, based on the opinions of experts from the prefectural center for infectious disease control.
