Two crowns confirmed in the karaoke room
Seoul’s “ventilation with the same air conditioning system” … increases the chance of infection between each
The possibility of direct infection cannot be excluded through door handles, vending machines, and restrooms.
On the other hand, Jung Eun-kyung, “the probability of spreading drops and contacts is higher.”
A case was found in a karaoke room in Dobong-gu, Seoul, where guests who stayed in other rooms at the same time were confirmed with coronavirus infection. The Seoul Metropolitan Government said it does not exclude the possibility of spread through the air conditioning system connected to each room in the karaoke room. If the corona is confirmed to have occurred through the air conditioning system, there is concern that the corona infection may occur in a building that circulates air in a tight space, such as some video rooms or high gardens. security. However, the city of Seoul said, “The exact cause needs more investigation.”
This karaoke visited the Itaewon club visitor (Gwanak No. 46) in close contact with confirmed patient Dobong No. 10, and then two of the karaoke visitors (Dobong Nos. 12 and 13) were further confirmed. Although Dobong No. 10 and No. 12/13 did not use the same room, it is estimated that the air conditioning system in each room connected to karaoke was not used as a propagation route.
However, a city official said: “It is not possible to exclude other possibilities that could have been extended through direct contact through the door handle, the vending machine, the toilet, etc.,” he said.
Karaoke-mediated crown spread can also be launched. There is one more karaoke room in addition to the karaoke in contact with Gangseo-gu # 31 on the Gwanak 45 patient line, which can be said to be the starting point of the infection at Hongik University. In addition, there are three karaoke rooms on Patient Route Gwanak 46, which is believed to have extended Corona to Dobong-gu karaoke in contact with Dobong # 10. Accordingly, authorities are focusing on identifying karaoke contacts.
Some estimate that the interior structure, in which a limited amount of air circulates through the air conditioning system to another room, can cause the crown to spread, while drops from the infected person sneeze up to 2m and float in the air for a while.
On the other hand, the quarantine authorities considered that the case was not a karaoke air conditioning system, but that it spread through droplets or contact between people. Jung Eun-kyung, head of the Central Defense Response Division, said at the regular briefing of the Center for Disease Control and Prevention this afternoon. It was done and it is possible that the splash would spread. “
“There may have been spread through contact and manual contact in public spaces like restrooms and toilets,” Jung said. “I think the risk of spread of time or space sharing is greater than it is now.”
