Leung Cheuk-wai: Omicron's spreading power is strong through injections, and it can't be zero infection. Advocate for restaurants to open early and evening markets

The government announced yesterday that it would extend social distancing measures such as the ban on dine-in dinners until the third day of the new year, and has repeatedly stressed the need to achieve "dynamic clearing".

Leung Cheuk-wai, a government expert advisor and Dean of the Faculty of Medicine of the University of Hong Kong, said on a radio program today (15th) that even if the vaccination rate is 100%, there is still a chance to be infected with the mutant virus Omicron, because Omicron's transmission is very strong, "the real system must be cleared and zero. Infection is an almost impossible mission.”

He pointed out that in response to the omicron epidemic, despite the advantages of real-name health codes and community inspections, the mainland has not been able to completely stop the spread of the virus. This shows that it is very difficult to clear it.

He suggested that restaurants can remove the partitions, but ensure that there is sufficient distance between the platforms, so that the early round and evening markets can be reopened from 6:00 to 8:00; outdoor sports venues such as football fields, tennis courts and golf courses can also be used. Relatively safe to reopen.

Leung Cheuk-wai, a government expert advisor and dean of the Faculty of Medicine of the University of Hong Kong, pointed out that the partitions in the dining room "have a psychological effect above all else" and will even affect ventilation.

Liang Zhuowei pointed out that the partitions of restaurants and restaurants can only prevent droplets, but Omicron has a high chance of being airborne. It makes the air unable to circulate." He believes that it needs to be inspected, and refers to the partition "psychological effect is greater than everything".

He pointed out that the government's implementation of the "vaccine bubble" is a good thing, but because even if the Fubitai vaccine is currently administered, it will not be completely free from Omicron infection, and the vaccine certificate may be just a "pass."

He said with a smile, "The virus won't come out after 6 o'clock, and I hope there will be less crowds." It is safer to sit sparsely in the room and remove the partitions.

As for the current closure of all sports venues, he cited tennis, golf, football and other venues with good ventilation outside. "Actually, if you ask me, I think they are safer." Can eat, the risk is not different, it is believed that it can be more humane and based on science.

He believes that the government needs to let citizens have a vision. If the vaccination rate reaches 90%, after the severe disease rate is greatly reduced, there is a timetable for returning to normal life.

Leung Cheuk-wai pointed out that Omicron is highly contagious. "It's really about zero infection, but it's almost an impossible task." Even if the vaccination rate in Hong Kong reaches 100%, it will be difficult to stop the spread of Omicron. A large number of restrictions imposed in many cities, the use of health codes and a large number of tests in a short period of time have failed to completely contain the Omicron case.

He said that the real-time reproduction rate of the Omicron virus is still estimated to be between 1 and 2.5, that is, each patient will transmit to more than one person, which means that the epidemic is not under control, and more people will still be diagnosed.

However, there is still "dawn", because the basic reproduction rate of the virus (that is, the transmission rate without any measures) is 6 to 10, which means that the government's measures are effective.

Whether there is a chance to control the epidemic on the fourth day of the Lunar New Year, he hopes it can be done, referring to the fact that the immediate reproduction rate has dropped 10 days ago, but it has never fallen below one or below. He believes that tracking and testing should be done to cut off all community transmission chains.

There is a saying that even without vaccination, Omicron infection will not cause severe illness. He believes that it is "too arbitrary". Although many people in the United Kingdom and South Africa have been infected with Omicron, the number of severe cases is small, and the number of suspected diagnoses and casualties is "off the hook". This is not the case in the United States, and it is believed that the "off-coupling" situation is mainly due to the young population of South Africa and the high vaccination rate in the United Kingdom.

Therefore, he is still worried about the epidemic in Hong Kong, especially the low vaccination rate of the elderly. "The mainland and Hong Kong can see no tsunami-like outbreaks today. It has been done well, and we must continue to bite the bullet."

He admitted that the Omicron virus is less likely to cause pneumonia, but mostly in the upper respiratory tract, but pointed out that the death risk of the elderly is 10 times higher than that of the young, "Do you dare to try?"

Earlier, Yuan Guoyong, a chair professor of the Department of Microbiology of the University of Hong Kong, suggested that citizens can wear two masks so that the masks are closer to the face.

Liang Zhuowei pointed out, "Wearing more than one will not affect your breathing or work. You can try this, but if a boss can buy a close-fitting mask, not a surgical mask, it will be hard for colleagues to wear two masks if they stick to the sides. ."

"Bitterness first, sweetness later" hopes to implement vaccine bubbles in restaurants on the fourth day of the Lunar New Year.
