中国でインフルエンザ患者が増加

Influenza disappeared from most of the world in the past 18 months, when influenza transmission was suppressed by the anti-COVID public health measures. But now influenza B is spreading again in mainland China and detections are increasing each week (1/9) pic.twitter.com/2HU2m4Pv0X

Given the loss of population immunity against influenza in the past year, it's quite possible that the flu season in the mainland this winter could be larger than average, potentially with >100,000 respiratory deaths caused by influenza (5/9) https://t.co/TRQx1bwTpM
