6) “so the quarantine authorities believe that a very strong virus was spread quickly through the wind of an air conditioner. there are voices of concern that the use of air conditioners has increased due to the end of the long rainy season and the heat wave has come in earnest”

7) “and that ventilation is difficult in some facilities, making it difficult to comply with these guidelines. In addition, it is pointed out that even if there is a guideline, a strong recommendation from govt should be accompanied as it is a matter for companies to cooperate.”

9) “Even if it is not, it is possible to propagate droplets of 2m or more in a closed space, and it is possible to propagate through hand contact and other public facilities. ***Taking off a mask in an indoor space is all dangerous behavior***, and please minimize those parts."

室内循環エアコン、換気不良空間+多人数のAirborne Transmissionと推測しますが、KF94 はフィッティングは悪そうですが、防御に寄与していますね。記事は読めませんが参考になりました。ありがとうございます😊 twitter.com/tyonarock/stat… pic.twitter.com/WAOnSS69Vj
