Abstract
BackgroundTo control the COVID-19 outbreak in Japan, sports and entertainment events were canceled and schools were closed throughout Japan from February 26 through March 19. That policy has been designated as voluntary event cancellation and school closure (VECSC).ObjectThis study assesses VECSC effectiveness based on predicted outcomes.MethodsA simple susceptible–infected–recovered model was applied to data of patients with symptoms in Japan during January 14 through March 26. The respective reproduction numbers for periods before VECSC (R0), during VECSC (Re), and after VECSC (Ra) were estimated.ResultsResults suggest R0 before VECSC as 2.534 [2.449, 2.598], Re during VECSC as 1.077 [0.948, 1.228], and Ra after VECSC as 4.455 [3.615, 5.255].Discussion and conclusionResults demonstrated that VECSC can reduce COVID-19 infectiousness considerably, but after VECSC, the value of the reproduction number rose to exceed 4.0.
Highlights
Results demonstrated that voluntary event cancellation and school closure (VECSC) can reduce COVID-19 infectiousness considerably, but after VECSC, the value of the reproduction number rose to exceed 4.0
The first is that even though we evaluated VECSC, the respective effects of voluntary event cancellation and school closure cannot be distinguished
Results have demonstrated that VECSC can reduce the infectiousness of COVID-19 considerably: approximately to one

To control the COVID-19 outbreak in Japan, sports and entertainment events were canceled and schools were closed throughout Japan from February 26 through March 19. That policy has been designated as voluntary event cancellation and school closure (VECSC). This study assesses VECSC effectiveness based on predicted outcomes
