Warning levels persist! The threshold has been exceeded again within the Tokyo metropolitan area!
Warning levels remain in effect across the city, and the number of reports per sentinel site is increasing. In Tokyo Metropolis, reports exceeded the warning threshold in Week 45 (November 3–9). After a temporary decline, the number of reported patients again surpassed the warning threshold in Week 5 (January 26–February 1). Because a further surge is possible, everyone should continue basic infection prevention measures to prevent and limit influenza spread, such as frequent handwashing, disinfection, and cough etiquette.
※〈About influenza advisory and warning levels〉
・The number of influenza patients reported by 419 pediatric and internal medicine sentinel clinics across the Tokyo metropolitan area is aggregated by public health center. An advisory is issued when the number of reported patients exceeds 10 per sentinel site per week; a warning is issued when it exceeds 30 per sentinel site per week.
・Tokyo Metropolis issues an advisory or warning broadly when either the total number of patient reports from sentinel clinics across the metropolis exceeds the advisory or warning threshold, or when the combined population of public health center jurisdictions at advisory or warning levels exceeds 30% of Tokyo Metropolis’s total population.
