The group with the latest small outbreak appeared in the Red Mr Karaoke Room in Tsim Sha Tsui. The diagnosis is confirmed, and the remaining 2 people need to be quarantined.

Infectious disease doctors point out that the K room is as dangerous as a side burner. There are four major factors, including the fact that masks may not be worn when singing K, or common microphones and other facilities being polluted. When everyone talks, they will fly away. One person with the virus can infect all people; everyone will stay in the same confined space for a long time; if there is an independent toilet in the K room, which is shared by the people in the room, the virus may also be transmitted through secretions. The doctor reminded that even wearing a mask in the K room is not the same as zero risk of infection. Because it is inevitable to take off the mask to eat, it may also be infected through other contacts.

Coexisting in confined spaces like a side burner, multiple shared facilities increase risk

Infectious and infectious disease specialist Zeng Yin described that singing K is as high-risk as a sideburner. The distance between people in the K room is closer, which increases the risk of infection. He also listed the high-risk factors in the K room one by one.

A recent study in the United States found that the new coronavirus can be suspended in the air for up to 3 hours under the atomization procedure. Zeng Qiyin explained that singing K is the same as playing a side burner. A group of people will stay in a closed space for a long time. If there is insufficient air circulation, the virus can stay in the environment for a long time.

He continued to point out that guests who patronize karaoke may not wear masks when singing, and they will also close the microphone peak to the mouth, and the microphone peak in the K room needs to be shared, and there is a chance of contagion. In addition to microphone peaks, there are also many shared facilities in the room, such as chairs and door handles. If there is a separate toilet in the room, if a person with a virus has used the toilet, the virus in the secretion may indirectly infect other people. user.

In addition to singing in the K room, there will also be other activities, such as eating, talking, playing dice cups, and even more intimate contacts such as hugs. The social distance is believed to be less than 1 meter. Without masks, there will be crowds. Flying horizontally, easily transmitted to others.

The Hong Kong Government has implemented a new law since 6 pm on March 28th. There can be no more than 4 people per table in restaurant premises. Since most karaoke restaurants hold restaurants, they are also subject to this restriction, but no karaoke is required. OK closed. Entertainment venues such as the Sparrow House are also unregulated.

Zeng Qiyin pointed out that it is difficult to understand that the government did not require karaoke to cease operations at the beginning, and if it is not “redressed as a government problem”, the next group outbreak may be the sparrow house.
