Yuan Guoyong and other four experts from the University of Hong Kong pointed out that Hong Kong has the conditions of "0+7" and the recent mortality rate is lower than 0.1%

The epidemic in Hong Kong continues. Yuen Guoyong, Chair Professor of the Department of Microbiology, Faculty of Medicine, HKU, together with three other experts from the University of Hong Kong, wrote an article titled "The New Crown Epidemic Will Do What We Want to Return to Hong Kong", pointing out that although the toxicity of the Omicron variant is reduced, "immune escape ability" Stronger, but still effective with 3 doses of the vaccine.

The team believes that the fatality rate of the epidemic has recently dropped to 0.097%. It is blunt that the new crown virus has become an endemic disease, and Hong Kong should gradually return to normal. It is emphasized that "Hong Kong is absolutely qualified to further realize the 0+7 plan, or even a more aggressive plan." In response to new situations and new problems, we must respond to the situation with new ideas and new measures.

The article was co-authored by Jin Dongyan, Professor of the Department of Biochemistry, HKU Faculty of Medicine, Yuan Guoyong, Chair Professor of the Department of Microbiology, HKU Faculty of Medicine, Long Zhenbang, Honorary Assistant Professor of the Department of Microbiology, HKU Faculty of Medicine, and Chen Fuhe, Clinical Associate Professor of the Department of Microbiology, HKU Faculty of Medicine. Famous" published.

They mentioned in the article that since the beginning of 2020, the new coronavirus strains have been mutating continuously. The Omicron variant has reduced toxicity, but its transmission has increased. After inoculating 3 doses of vaccine against the prototype virus, or being naturally infected by different strains, the chance of infection is greatly reduced. , the probability of severe illness and death is extremely small. Even if the new variant has immune escape, the existing vaccine is still effective, and the effect of booster injection is better.

Low chance of new variants of new coronavirus with high pathogenicity

Several experts believe that the chances of emerging new variants of the new coronavirus with high pathogenicity in the future are quite low. In the next 12 to 24 months, new variants of immune evasion are likely to appear, "Even if the antigenic drift of influenza virus can cause hundreds or even thousands of deaths in Hong Kong every year, new variants of the new coronavirus are no exception. "

New coronavirus infection has taken root in Hong Kong as an endemic disease

The four experts who wrote the article also pointed out that the crude case fatality rate of the epidemic has dropped to 0.097% since June, the effective reproduction rate is low, and the seasonality is becoming more and more obvious, which is basically close to the seasonal flu, "The public should start to understand the new crown. The virus infection has taken root in Hong Kong and has become a fact of endemic disease. Now that the epidemic has eased, it should gradually start to relax and return to normal.”

In terms of vaccination, the team believes that the community should respect citizens who are still hesitant to get injections. Under the resumption plan, they can do antigen tests every day. If they are infected, they should seek medical treatment and take oral antiviral drugs as soon as possible.

The government should also consider implementing the Phase 4 vaccine pass as soon as possible, cancel the restrictions on the business hours of restaurants and the number of people per table, and allow those who have completed 3 injections to return to normal life while wearing a mask. The 0+7 plan of isolation, or even a more aggressive plan, accelerates the return to normal.”

Advocating for the supply of children's Fubitai as soon as possible, Zhong Nanshan suggested that the elderly should be given mRNA vaccine for booster

The article pointed out that there will always be parents who hold a skeptical and wait-and-see attitude and hesitate to vaccinate their children.

Therefore, there must be practical actions, such as supplying children with Fubitai as soon as possible, so that parents can have one more choice.

According to the suggestion of Zhong Nanshan, an academician of the Chinese Academy of Engineering, the elderly and patients with chronic diseases who have been vaccinated with inactivated vaccines should choose mRNA vaccine or recombinant protein vaccine as a booster, and the effect is better.

"Faced with new situations and new problems, we must respond with new ideas and new measures"

In terms of public hospitals, the authorities can adopt appropriate and effective infection control measures. For example, it is not necessary to limit the virus load to a certain level before discharge, so that public hospitals can divert patients, maintain a balance in the number of admissions and discharges, smooth patient discharges, and reduce detention.

The four experts believe that the community in Hong Kong has basically established a barrier to prevent severe illness, and now it is time to consider changing formations and relax and return to normal as soon as possible, so that citizens can have sufficient mixed immunity before winter comes and enhance their resilience against the epidemic. "Faced with new situations and new problems , we must adapt to the situation and respond with new ideas and new measures.”
