The new crown epidemic has rebounded greatly, and the Omicron variant virus has entered the community.
In addition to the Indian helper, his employer and the young master who were infected with the virus in Meixin Building in Tai Po earlier, a resident in Room D upstairs was initially diagnosed with the same location as them.
Yuan Guoyong, a government expert consultant and chair professor of the Department of Microbiology of the University of Hong Kong, visited the site today (9th) and believed that there was vertical transmission in the building. Therefore, the residents of Room D from the 6th floor to the 24th floor should be forced to evacuate for quarantine, involving 19 households.
Looking through the information, the last time a large-scale evacuation operation was carried out from the building was at Tsuen Wan Gardens on May 4 last year, when a newly arrived Filipino maid was infected with the N501Y variant virus.
After an Indian domestic helper and his employer's family contracted the virus earlier, another confirmed case was reported in Meixin Building in Tai Po.

3 people in the 5D unit of the Indian helper were diagnosed with the virus and the 10D room did not know each other
An Indian domestic helper (#12854) was diagnosed earlier, and her employer and the 13-year-old young master were also initially positive, involving a total of three people.
Among them, her employer once watched Henry Zhang's concert with her husband on the evening of January 3.
In addition to the confirmed cases in the above-mentioned units, during the mandatory testing of Meixin Building, it was also found that the virus was detected by residents of the same block, and there was vertical transmission.
The new confirmed patient is a 66-year-old retired woman who also lives in Room 10D.
The previous case lived in Room 5D, and the two households did not know each other and had no history of contact.
According to the data, the Indian maid (#12854) belonged to the dance group that was detonated by the flight attendant. She and another foreign maid (#12805) had been to the North Point Seaview Building Church, and No. 12805 was the foreign maid of a dancer.

The newly infected unit has installed a U-shaped air barrier in the shower and dried up
After an inspection, the EPD stated that the building had just completed repairs in 2018, and all drainage pipes had been updated, so the drainage pipes were "in good condition".
However, the 10D unit has been modified. One of the rooms has been equipped with an ensuite toilet, and a new drainage pipe has been added to the ensuite toilet. Therefore, it is different from other units. It is estimated that this may cause transmission opportunities.
Yuan Guoyong: There may be a "chimney effect" virus rising through the sewage
Yuan Guoyong said that there was vertical transmission in the building, and the virus of the three confirmed patients in Room 5D was likely to be transmitted to Ms. Chu Que in Room 10D.
After inspection, he believes that the greatest possibility for the time being is the "chimney effect", that is, warm air rising up through the sewers.
He explained that since the toilet in Unit 10D had been refitted, and the shower was not used, the U-shaped air trap of the ground canal was dry, especially when the exhaust fan was turned on, a strong negative pressure was generated, so the air from the sewage canal enters Inside the house, which in turn infected the lady in Room 10D.
Yuan also pointed out that since the air from the pipes will come out of the patio, the high-rise units may be infected by the "turbulence effect", so the residents of rooms 6D to 24D should evacuate.

The last evacuation operation involved more than 220 households in Tsuen Wan Tsuen Wai Garden in May last year
After reviewing the information, the last time a large-scale evacuation operation was carried out in the building was at Tsuen Wan Gardens on May 4 last year. The authorities announced that asymptomatic occupants of all floors of the building where the patient lived (Block R, Tsuenway Gardens) would be sent to Go to the quarantine center, involving more than 220 units, and arrange evacuation on the morning of May 5.
At that time, because a newly arrived Filipino domestic helper was infected with the N501Y variant virus and lived at the employer's house in Block R, Allway Gardens, all residents of the building had to be evacuated from quarantine.
Omicron│The number of foreign domestic helpers gathered in Victoria Park has greatly reduced. The Indian helper group exclaimed: Oh My God compulsory testing | Eight community testing centers extended their services until 10:00 p.m. On-site registration of the Fishing, Farming and Food Carnival was suddenly closed. Helping farmers with bulk goods: I hope that the first confirmed female employer of the Indian helper group is Niuchiwan Jinhui Real Estate staff area.
