Abstract

In this study, ventilation methods and quarantine methods for infected persons were evaluated as measures to reduce airborne infections in elementary schools. The minimum ventilation rate by mechanical equipment was calculated based on 20 people. As a result of the study, it was found that the minimum ventilation using mechanical ventilation has limitations in preventing the spread of airborne infection. However, it has been shown that securing a natural ventilation of more than 10 ACH throughout the day can effectively prevent the spread of airborne infection, but it is inevitably a limited alternative depending on the characteristics of the building. On the other hand, rapid isolation of infected persons has been shown to be very effective in preventing the spread of airborne infections. It is noteworthy that if an infected person can be isolated immediately after the first class, the spread of airborne infection can be effectively prevented even in everyday situations without wearing a mask.
