A new variant virus strain is suspected to be circulating in the community in Hong Kong.
Au Ka-wing, chief physician of the Infectious Diseases Division of the Centre for Health Protection, said that there were 4 L452 cases in Hong Kong with a mutant virus, which is suspected to be a local case, which is different from the currently circulating virus strain. It is suspected to be an Omicron mutant virus subtype BA.2.12.1. Whole-genome analysis of the 4 cases will be conducted, and the relationship between the 4 cases and the McDonald's group in Cityplaza, which is also involved in BA.2.12.1, will be investigated. Now it is only found that the four cases and a 76-year-old mother-in-law in the McDonald's group were both in the same group. They have been spotted in Wanchai recently. If the whole gene sequence of the four people is the same as that of the McDonald's group, it proves that the variant virus has entered the local community.
There is one more case in the McDonald's group today, a 99-year-old mother-in-law. Although she has never been to McDonald's in Taikoo Shing, her genetic sequence is the same as that of the 76-year-old mother-in-law on the same floor and in a different orientation. There are currently eleven in the group. People are infected.

Four cases under investigation and McDonald's group relationship group 76-year-old mother-in-law who went to Wanchai
Au Jiarong said that although the two patients both work in Wanchai, they have not yet seen any epidemiological connection between them, nor have they been to the same place, and will investigate whether the two have ever met.

McDonald's group adds a 99-year-old mother-in-law to the Regent Garden
As for a new 99-year-old mother-in-law in the McDonald's group today, she was found to have been vaccinated during the forced inspection of the Regent Garden on May 19, with a CT value of about 18 to 19. She is currently recovering. A few days ago, the quick test result was negative. She had never been to McDonald's in Taikoo Shing, but her genetic sequencing analysis was the same as that of the 76-year-old mother-in-law who was diagnosed in the same floor and different orientation. in this group.
The 99-year-old mother-in-law lives with the worker. The worker tested positive on May 23, and will check whether the worker belongs to the McDonald's group after the genetic sequence of the worker is released.
At present, a total of 9 diners, 1 family member of the diners and the 99-year-old mother-in-law at McDonald's have been infected, a total of 11 people have been infected.
Ou Jiarong: There is no strong scientific evidence to prove that the branch has more severe symptoms
Ou Jiarong continued to point out that the Ba.2.12.1 virus branch has only appeared in the world in recent months. Due to limited scientific data, according to WHO data, it is derived from Ba.2. Similar to Ba.2.2.2, its transmission power may be higher than that of other Ba. 2 Stronger, but there is no strong scientific evidence that the branch has more severe symptoms.
