Scientific basis for social distancing during the period of COVID-19.

Recently, the COVID-19 Central Disease Control Headquarters and the Korea Institute of Science and Technology (KIST) analyzed the relationship between meeting time, number of meetings, number of ventilation, and risk of COVID-19 infection using a mathematical model (spread simulation model and actor-based model). It scientifically verified the effectiveness of social distancing.

As a result of this study, the risk of infection is 60 percent if you meet for 12 hours, while the risk of infection is reduced to 35 percent if you reduce the time you meet to 4 hours.

During the 12-hour meeting, the risk of infection decreased to 78% if ventilation was not performed at all, 60% if ventilation was performed once every 30 minutes, while 42% if ventilation was performed once every 10 minutes.

The risk of infection was 22% by reducing the meeting time to 4 hours, ventilating once every 10 minutes, and 14% by reducing the meeting time to 2 hours.

In addition to the usual people, if the number of meetings they meet after a long time is reduced by 40%, the overall number of COVID-19 confirmed cases can be reduced by 33% after 1.5 months.

Based on these research results, the guidelines for recommending social distancing by the Korea Centers for Disease Control and Prevention are as follows: First, reduce meeting time than usual. Second, reduce the number of meetings than usual. Third, if you meet, ventilate continuously. Fourth, always wear a mask and do not talk during meals. Lastly, get vaccinated.
