    SEOUL, SOUTH KOREA, May 4, 2021 – The Seoul Metropolitan Government launches the “Open the Window” campaign so that Seoul citizens actively practice indoor ventilation in their daily lives.

    For the past four months, from January 1 to April 19, 900 COVID-19 infections, or 30.7 percent of the total cluster infection cases (2,935), in Seoul have occurred at poorly ventilated facilities, such as indoor sports facilities and call centers. In April alone, 349 cases, or 38.7 percent, were infected with the virus at those facilities.

    In a bid to curb the spread of COVID-19, the Seoul Metropolitan Government announced its recommended rules about indoor ventilation while extending the social distancing level 2 by three weeks. The Seoul Metropolitan Government also stages the “Open the Window” campaign to encourage the citizens to realize the importance of indoor air ventilation and participate in the campaign.

    According to the rules, windows and doors are recommended to be always open unless there are any particular civil complaint factors, such as noise. If a facility has difficulty opening the windows and doors during business hours, it is recommended to air out the facility for at least ten minutes every hour.

    If a facility has no windows or has difficulty opening windows because it is located in the basement, it is recommended to open the windows and doors connected to the passageways and operate ventilators. When running an air conditioner or heating system, opening some of the windows is strongly recommended.

    In the case of indoor sports facilities with a higher possibility of excessive droplets, the frequency of ventilation should be increased. All windows are opened for more than 15 minutes before and after business hours.

    Since there are many cases in which people exchange conversations without wearing masks at home, the Seoul Metropolitan Government asked the citizens to follow the rules at ordinary houses as well.

    The Seoul Metropolitan Government said the “Open the Window” campaign that takes actions jointly with the citizens to minimize the risk of infection at indoor facilities, where the cluster infections occur the most, along with the extended Special Quarantine Week to contain the coronavirus.

    Park Yu-mi, General-Director of Citizens’ Health of the Seoul Metropolitan Government, said, “Recently, we have about 700 new confirmed cases a day nationwide. It has been proven to drastically reduce the confirmed cases just by changing the air, which is the thing anyone can do.” She added, “I hope as many citizens as possible join the “Open the Window” campaign so that we can make the city safer and achieve practical effects.”
