A 23-year-old female employee of the Little Boss pet shop in Jardine's Street, Causeway Bay was infected with the Delta AY.127 variant virus. Xiao Jieheng, associate professor of the Department of Medical Technology and Informatics at the Polytechnic University, said in a radio program today (18th) that her team



A 23-year-old female employee of Little Boss pet shop in Jardine's Street, Causeway Bay was infected with the Delta AY.127 variant virus. Xiao Kit-hang, an associate professor of the Department of Medical Technology and Informatics at the Polytechnic University, said on a radio program today (18th) that her team tried to compare the imported cases in Hong Kong and found it to be The Pakistani woman who arrived in Hong Kong on December 25 had relatively similar virus genes, but there were still 17 mutations. It was believed that the transmission link between the two could be denied. However, no similar genes could be found in the international genetic database, and the infection route was described as "nothing." head case".


Xiao Jieheng emphasized that the patient had the opportunity to be infected by the invisible patient of the imported case, and emphasized that "a community will not be left without a mutant virus", and another direction of investigation is to be infected by hamsters in the pet shop where he works, because The hamster itself can be infected with the new crown virus. It is believed that the situation is similar to the Alpha case of unknown origin in June last year, and it is worried that the epidemic will spread in the community.


Gene sequencing and the latest delta input have 17 places respectively that can deny direct or indirect association between the two

Xiao Jieheng said on the Hong Kong and Taiwan program "Millennium Times" that a 23-year-old female pet store employee had the Delta AY.127 variant virus. The PolyU team tried to compare the imported cases in Hong Kong. There were 3 Delta imported cases in December, and the latest one was The Pakistani woman who arrived in Hong Kong on December 25 still has 17 mutations in their genetic sequences, which can deny the direct or indirect transmission link between the two.

Delta AY.127 is more popular in Pakistan, but it is different from the genetic sequencing of infected pet shop assistants

His team later compared the international gene database, and the relatively similar gene sequences came from the Czech Republic, but he emphasized that the international gene database does not contain all virus gene sequences in the world, and there are relatively few developing countries. He also pointed out that AY.127 is in Pakistan. It is relatively common, but the genetic sequence of the 23-year-old infected woman is also somewhat different from the virus in the country. The infection route of the patient is still described as a "headless koan".

Xiao Jieheng infers that there is a Delta invisible transmission chain in the community: there will be nothing but the virus

Xiao Jieheng inferred that the infected pet shop woman may still be infected by the invisible patient of the imported case. "A community will not be without a mutant virus", and she has never set foot overseas, so she has a great chance of having a Delta Invisible chain of transmission, infecting the woman.

Regarding the opinion that the Delta case had hit Hong Kong as early as Christmas, Xiao Jieheng said that it is impossible to infer when the virus rushed into Hong Kong. This case still has 7 different mutations from the most recent similar virus found in the Czech Republic, " The 7 mutations mean that the virus should be... not necessarily in Hong Kong, compared with the last one.” There are differences for several months. According to our analysis, this virus will accumulate 1.8 per month. mutation.

Animal-to-human transmission is the direction of investigation. Hamsters can carry the new coronavirus

He specifically mentioned that another direction of investigation is animal-to-human transmission, especially if the patient works in a rodent pet store. "The hamster itself has an ACE2 receptor attached to it, so it can infect the new coronavirus", and she last Tuesday (11th) Not feeling well, the diagnosis was not confirmed until yesterday (17th), and it has been in the community for many days.

However, he emphasized that because there was a similar case of Alpha infection in June last year, but there was no community transmission, the public need not worry too much about the two variants attacking Hong Kong.

A biography of a Pakistani woman, Xiao Jieheng: For the first time, the OmicronBA2 subtype has entered the community

As for the 43-year-old Pakistani woman (#13045) who is suspected of contracting the virus at Silka Seaview Hotel, nine of her relatives and friends have been infected. Xiao Jieheng said that the flight attendants group in North Point and the Wangyuelou group are both BA1 subtypes, and this case It is the BA2 subtype, which is the first time this virus has entered the community.

He continued that the virus had flooded into Asian countries earlier and caused major outbreaks in the Philippines, Nepal and other places. Many imported cases from the Philippines who arrived in Hong Kong last week all contained the BA2 variant virus, but the subtype of the virus is currently unknown. "But it must be the case, he has already triggered another transmission chain", even reaching 1 to 9. If 9 relatives and friends are infected with 9 more people, forming a giant transmission chain, the severity may be higher than that of the North Point group. stronger.
