Four more people were diagnosed with "new coronavirus" in Hong Kong. The patients all lived in Luquan Building, Liyuan Village, suspected to be related to the Kerry warehouse group. Yuan Guoyong, a lecturer professor of the Department of Microbiology of the University of Hong Kong and many other experts and government representatives, went to the unit of the diagnosed person last night (June 1) to understand that there was no structural transmission problem in the building, so there is no need to evacuate the building residents. However, after investigation, it is suspected that the building has a chain of transmission or even a "super communicator". Therefore, all residents are urged to conduct a deep throat saliva test as soon as possible, and to ensure personal hygiene, wear masks, etc., because the virus is not excluded in the public space of the building, including through Mailboxes, lobby doors, etc.

Yuan Guoyong, Chair Professor of the Department of Microbiology of the University of Hong Kong, Huang Jiaqing, Director of the Center for Health Protection, Zhang Zhujun, Director of the Infectious Diseases Department, and Xie Zhanhuan, Deputy Director of the Environmental Bureau, and other government representatives, arrived at the Liyuan Village Housing Department late yesterday (June 1) for a meeting And went to the unit involved in Luquan Building to conduct an investigation, and took environmental samples.

Huang Jiaqing, director of the Center for Health Protection, told reporters at the scene that a couple earlier in the Luquan Building of Liyuan Village had been diagnosed on May 31. The center collected deep throat saliva samples from residents. The laboratory was yesterday (June 1) Notice that 4 other residents were diagnosed. Yuan Guoyong, Chair Professor of the Department of Microbiology at the University of Hong Kong, pointed out that the female patients who worked in Kerry Logistics were diagnosed earlier and believe that Kerry Logistics has a transmission chain; at present, Luquan Building also has a transmission chain, which is spread to 4 units on different floors , Including two units on the same floor, and the other 2 units are on other floors.

Xie Zhanhuan, deputy director of the Environmental Bureau, pointed out that after on-site inspections, there was no structural risk of infection in the units of the diagnosed persons, including the problem of U-shaped water traps like Amoy Gardens; there was no Tsing Yi Kang Mei Building The problem of the modified dung canal; there is no "building turbulence effect" in Heng Tai Building in Tai Po.

Yuan Guoyong, Chair Professor of the Department of Microbiology at the University of Hong Kong, pointed out that since there are no structural problems mentioned above, there is no need to evacuate the entire building. Asked whether the residents of the building should go to work or school, Yuan believes that as long as they do enough personal hygiene, including wearing masks and hand cleaning, they should not be overly worried. There is no need to trap residents in the building to avoid panic. He pointed out that due to the time, place and households of the infection, they believed that there were group cases.

Professor Yuan continued to point out that he initially learned 4 units, 2 of which were "21" units. Two of them are on the same floor. Among them, 3 units with diagnosed patients, or sharing 2 lifts, do not rule out cross-infection in the lifts or spread through buttons. In addition, they also found that the mailboxes of the four units are quite close, and residents may also be infected when sliding the gates. Therefore, it is not ruled out that the virus is spreading in the public space facilities of the building, and it is not ruled out that "super spreaders" have appeared. He urged all residents of the building that "early morning" (June 2) should carry out a deep throat saliva test, if they are positive, they should be quarantined as soon as possible.

He continued that the biggest problem at present is the insufficient number of tests. At this stage, social distance measures, even if they decrease or increase, are unwise.

The HD posted a notice at the entrance of the building, saying that on June 2 and June 3 from 9:30 to 11:00 am, the CHP will collect deep throat saliva samples from residents of the building.
