Is the new crown pneumonia flu-like? Jin Dongyan, an expert from the University of Hong Kong: It is the common cold that is weaker than the flu

The new crown pneumonia is becoming an endemic disease. Whether it should be regarded as a common cold, flu, or as the director of the Medical and Health Bureau, Lu Chongmao, said: "Omicron is not a flu, it is so simple", which has become a recent controversy.

Recently, he wrote an article together with experts such as Yuan Guoyong, chair professor of the Department of Microbiology of the Hong Kong University School of Medicine, and other experts. Jin Dongyan, a professor of the Department of Biochemistry of the Hong Kong University School of Medicine, who proposed that the new crown has become a local disease It is believed that the new crown will eventually be similar to the other four human coronaviruses that only cause the common cold, with a weaker pathogenicity

. , as long as the virus continues to be prevalent in Hong Kong and vaccination continues, there will be no major outbreaks in Hong Kong. On the contrary, if Hong Kong insists on "clearing", there will be "super spreading soil". "Before the major outbreak occurred in February and March, the It's just "clearing" for a while."

The nature of the new coronavirus will only get weaker

It has been nearly three years since the new crown pneumonia epidemic, and Hong Kong people have become accustomed to the existence of the epidemic from the beginning when they were afraid of the epidemic.

In an exclusive interview with "Hong Kong 01", Jin Dongyan said that the innate nature of the new coronavirus will only become weaker and slower, so even if there are more variants of the new coronavirus strain in the future, the pathogenicity may not be severe, and it will Like the other four human coronaviruses, OC43, 229E, NL63 and HKU1, which ultimately only cause the common cold, "sometimes it may be a little bit worse, but overall it's getting weaker and weaker."

The new crown pneumonia is not flu-like, it is the common cold, and it is weaker than the flu.

He emphasized that the purpose of the virus is to continue to survive, and the mutation is only to adapt to the human body and immune escape, but the virus will not mutate infinitely to "complete immune escape". will die”, so the antibodies produced after vaccination or infection are still useful in the fight against new coronary pneumonia.

The slowdown in the mutation rate of the new coronavirus means that the body is beginning to adapt

He revealed that the mutation rate of the new coronary pneumonia has become slower and slower, which means that the virus has begun to adapt to the human body. The government should set up a mechanism to monitor mutated virus strains to detect new variants of the new coronavirus as soon as possible, but there is no need to take strict measures as before to cut off the chain of transmission, such as interrupting flights and quarantining related patients for 21 days.

Jin Dongyan published an article as early as January 2020, predicting that the new coronary pneumonia will eventually evolve into a common cold, and advocated that China should manage the new coronary pneumonia as a Class B infectious disease from the end of 2020, that is, the epidemic situation still needs to be monitored, but there is no need to use the highest Standard quarantine measures prevent the spread of the virus, "You don't lock down the city because of the common cold."

A lot of people, including famous doctors in the city, just started talking nonsense without knowing it, saying that the virus is getting stronger and faster, but it doesn't really matter.

In an exclusive interview with "Hong Kong 01", Jin Dongyan, a professor at the Department of Biochemistry of the Faculty of Medicine of the University of Hong Kong, believed that the new crown pneumonia has been "demonized" in the past.

Although the death rate of Covid-19 has dropped significantly, many people will still die if there is a super spread.

Jin Dongyan believes that due to the high vaccination rate of Hong Kong people and the fact that many people have been infected earlier, there are only a few people who are not immune to the virus, which is not enough to make Hong Kong have "super spread soil". Too many people in the land have not been given injections to cause a major outbreak, affecting those who have been injected."

However, he emphasized that the elderly and people with low immunity should be vaccinated, because the mortality rate of the new crown has dropped to 0.06% and 0.03% after three injections of Kexing or Fubitai, which can reduce the risk of severe illness after infection. "The mortality rate If it is lower than the flu, basically if you get all the vaccines, you will not be able to do it.” He believes that it is still necessary to implement a “vaccine passport”.

Clearing is waiting for the big explosion, ..., unless you can constantly vaccinate people, but it can be done according to a no-brainer.

Insisting on "clearing" will cause the immune barrier to fail over time

He also pointed out that by insisting on "clearing", Hong Kong's immune barrier will fail over time. At that time, if there is an influx of cases, it will cause an outbreak. "Zero" lasted for a while." He said that natural infection can provide better mucosal immunity, and if vaccination is added, immunity will be stronger.

He reiterated that as long as the virus continues to circulate in Hong Kong and Hong Kong people are vaccinated regularly, there will be no major outbreak.

Before the fifth wave of the epidemic, there had been no local cases in Hong Kong for more than a year, so the University of Hong Kong could not calculate the immediate effective reproduction rate at that time.

The use of vaccines can be reduced to 5 years old. The food industry is expected to have another setback in business, and the national day zero banquet promotes the relaxation of the gathering limit of more than 20,000 sheets of non-needle-free paper on 10.12. 5-year-old parents bring their children to catch the last bus to get injections and those arriving in Hong Kong who fail to do nucleic acid tests on time are still issued a "blue code" Department of Health: There are measures to remind the epidemic | 4,269 confirmed cases and 5 more deaths today The school reports 498 teachers and students Infected
