So far, 15 residents and 1 security guard have been infected with the virus in the building, covering 11 floors and a total of 12 units.


Siu Kit-hang, an associate professor of PolyU's Department of Health Technology and Informatics, said on the RTHK program "Millennium" that the incident reflected that the virus "spreads very fast in Kowloon West", describing that multiple chains of transmission may have been planted, but it is estimated that female kindergarten teachers may not be directly Infection from a Pakistani mother and child may be infected by an undiagnosed third party.

Xiao Jieheng said that a 79-year-old Weng and a 53-year-old male airport forklift operator were diagnosed in the building successively, and Omicron "BA.2" was detected, which was similar to the virus strain of a Pakistani woman (case 13045). The 1-year-old baby was diagnosed, and the investigation found that he had also visited the mother-in-law in the building, reflecting that "BA.2" had caused a major outbreak in Yak Kwai Building.

After investigation, it was found that the husband of the Pakistani woman (case 13064) had collected items from the refuse rooms of Yikui Building, Lvkui Building and Qiankui Building in the middle of the month. Xiao estimated that there would be cases in the next few days, and urged residents to be careful when entering or leaving. Pay attention to hand hygiene and wear two masks when going out.

He said that the Pakistani woman had "passed 9 cases" earlier, and her son had also infected the schoolmates, reflecting that the virus "spreads very fast in Kowloon West".

Kindergarten teacher or undiagnosed third party infected

As for whether the 26-year-old kindergarten teacher ever met the two infected sons of a Pakistani woman who briefly met in the tunnel of the MTR station and became infected, Xiao Jieheng believes that Omicron's transmission power is stronger than that of Delta, but whether they met in the tunnel while wearing a mask 9 seconds have been infected, and it is estimated that it may not be the final route of transmission. "If it is really sharp, the tunnel can be infected, and the crisis of entering the carriage may be even greater."

He believes that the virus may have planted multiple chains of transmission in Kowloon West, and the female teacher may not have been infected directly from the Pakistani mother and child, but may have been infected by an undiagnosed third party.

In addition, the Delta variant virus was detected in the hamsters and warehouses of the pet store Little Boss, but the virus genes of the infected salesperson and female customer differed by 4 SNPs (single nucleotide polymorphisms).

Xiao Jieheng pointed out that female customers may not be directly infected by salespersons, but are more likely to be infected by animals.

He explained that hamster samples from different branches and warehouses of the pet store were positive, and the virus genes of the salesperson and customers were different, meaning that Delta was not transmitted from person to person in the community.

As for the 17-year-old boy who has not been to the store and has not kept hamsters, he has the Delta AY.127 virus, but he has 17 genetic mutations different from the salesperson.

He estimated that the boy may have forgotten to be in contact with animals, or that his friends and family have kept hamsters, so he will know the transmission route depending on whether his close contacts are infected in the next few days, but he believes that it is related to the hamster group.
