The Effect of Ventilation Rate in Controlling Airborne Infection

摘要：

Literatures showed that increasing ventilation rate could reduce the airborne infection risk. This paper discussed the effect of ventilation rate, ward size, number of infector and susceptible in controlling airborne transmitted diseases using Wells-Riley model which was based on the concept of quantum of infection and the concentration decay equation which expressed the relationship between ventilation rate and calculated pollutant concentration decay. The purpose of this study did not try to recommend the ideal minimum ventilation rate but tried to find a more scientific method to define minimum ventilation rate instead of current using Air Change per Hour (ACH).
