Liang Zichao said that cross-infection in quarantine hotels sometimes occurs, because the air out of the room is faster than the air in. After part of the indoor air is exhausted out of the corridor, it will be brought to the adjacent rooms with the air flow in the sealed corridor. Air volume or filtration will slightly reduce the risk, but there will always be short-distance transmission, and the air dilution rate is not as fast as walking to the adjacent room, so it is recommended to avoid unnecessary opening of the door, and wear a mask when opening the door.
He also suggested that people in quarantine should be arranged to stay in adjacent rooms according to their quarantine days, explaining that it can prevent new occupants from infecting people who are about to complete quarantine, and then bring the virus into the community.
Promoting the use of deep throat saliva bottles to collect samples, otherwise it will become a major weakness in prevention and control
Yesterday, a 23-year-old female employee of a pet shop in Causeway Bay was diagnosed with an unknown source of suspected Delta Variant Virus.
Liang Zichao believes that the government will give up the promotion of people with mild symptoms and risk factors to be tested through deep throat saliva as soon as possible, or delay the diagnosis of hidden cases due to the time cost, and the virus has the opportunity to spread in the community, "This is a big weakness in prevention and control. ...I do not encourage you to take a bottle and do deep throat saliva? For those with symptoms and willing to cooperate, but not forced to test, deep throat saliva is sensitive and convenient, and there will be no cross infection, which is more likely than other testing methods. better."
Delta plus Omicron may not increase the transmission power Liang Zichao: The chances of two simultaneous infections are similar to the lottery lottery
As for whether there will be a mixture of two mutant virus strains in Hong Kong, Leung Tsz-chao believes that after a large number of tests, the density of relevant cases is extremely low. He believes that there is no need to worry too much at this stage. It's about the same as the Mark Six."
