Yuan Guoyong, a government expert consultant and chair professor of the Department of Microbiology of the University of Hong Kong, visited the site today (24th). The case involved 3 units.

In some units, the drains are not poured and only sealed with adhesive tape
The representative of the Environmental Protection Department said that they had entered two units to inspect and found that the toilets of the units on the 8th floor had been changed; and the location of the drain on the 7th floor was sealed with adhesive tape. Kai walked out, so I suspected that the throat was dry.
Yuan Guoyong, chair professor of the Department of Microbiology of the University of Hong Kong, said that there are currently cases in Unit E on the 5th, 7th and 8th floors, so it is estimated that there will be upward vertical transmission.
Yuan Guoyong also pointed out that the 5E unit on the lowest floor had raised a hamster, and the environmental samples of the pet shop in Tongcai Street had detected Delta virus, "There is reason to believe that the Delta transmission chain has already begun, and it may be caused by the hamster. cause."
Yuan also said that there was no water in the drains of some units, and some residents were sealed with adhesive tape to prevent the cockroaches from going out.
However, Yuan emphasized that the adhesive tape is difficult to seal tightly. When the exhaust fan is turned on, it is easy to extract the air from the dung canal, and the throat is dry, so it is easy to be infected.
Another possibility involves patios. Because the patios of the building are deep and narrow, when the ventilation fans on the lower floors are turned on, the virus-laden air may be drawn out. When the warm air goes up, vertical transmission of the chimney effect may occur. .
