The COVID-19 outbreak in the South Korean city of Jeonju began in a restaurant. Analyzing these cases, Korean epidemiologists made several important conclusions that are very relevant on the eve of the holidays, when people will meet more in bars and restaurants.

The study, published in the Journal of Korean Medical Science, used data on the location of smartphone users, video recordings in a restaurant, and special devices that measure the speed and direction of airflow in rooms. According to Medportal.ru, epidemiologists found out that one of the restaurant's visitors became infected within 5 minutes while at a distance of 6.5 meters from the infected person. However, they did not contact each other in any way. According to scientists, the virus can be transmitted by airborne droplets at a distance of more than 2 meters, provided that the airflow comes from the infected person.

The risk of infection can also be increased by talking while eating, especially in a raised voice. The more and louder an infected person speaks, the more droplets are released from his body.
