Abstract

This study evaluated the impact of airborne infection prevention measures by Wells-Riley equation to provide basic information for infection control in elementary schools. At first, the Wells-Riley equation is modified to reflect prevention measures against airborne infection such as facial masks, ventilation and air purifiers. Afterward, 22 scenarios are established to evaluate the impact of airborne infection prevention measures. The results indicate infector screening by fever check is the most influential followed by hi-efficiency mask (KF94), ventilation, cotton-mask, air-purifier. Especially, when an infector is present, airborne infection risk can be reduced effectively only when both of wearing masks and ventilating are well done. Cotton-masks are useful but have limited effect, and air-purifiers can be used as auxiliary measures.
