The metropolitan government had issued its first such advisory for this season in October, followed by a warning in November, both of which were later lifted. This marks the first time in 17 years, since the 2008-09 season, that a new advisory has been issued after a warning was lifted within the same flu season. According to the metropolitan government, the number of patients reported per designated medical institution in Tokyo during the week of Jan. 19-25 reached 13.83. Reports of suspected influenza outbreaks at schools and social welfare facilities in Tokyo this season had exceeded 6,000 cases by Sunday.
