TREE NEWS reports: Japan’s Ministry of Health, Labour and Welfare reported 42,320 influenza cases at designated medical institutions nationwide for the week of Sept. 28 to Oct. 4, about 7.3 times the same period last year and 1.6 times the prior week. The average of 11.35 cases per institution marks the first time this flu season that Japan has reached the ‘attention’ alert level.
Japan Reports Over 40,000 Flu Cases in One Week, 7x Last Year
The jump to the 'attention' threshold this early in the season is the notable signal, since reaching it at all normally comes later in the flu calendar. The scale of the week-on-week and year-on-year increase points to a faster-than-usual spread rather than a localized cluster, which matters for how hospitals and clinics staff up ahead of winter. Whether the weekly count keeps climbing from here, or this is an early spike that flattens, is the open question.
