On November 24th, virologist and Professor of School of Biomedical Sciences, The University of Hong Kong Li Ka Shing Faculty of Medicine, Dong-Yan Jin, was interviewed by DeepMed and gave many insights on Omicron and epidemic prevention measures.

We can now have a relatively clear conclusion from the study of Omicron, that it is actually created to adapt to the environment in which the human body has resistance.
The premise of its survival is that the human body already has immunity, so its innate pathogenicity must be substantially reduced. It can also be said that it reduces pathogenicity as a condition or cost to increase immune escape so that it can grow and replicate in people who are already immune. So it will cause breakthrough infections, that is, vaccinated people will still get infected, so in 2021 when everyone is vaccinated and has antibodies, it will become the dominant strain. If the majority of the world’s population is unvaccinated and uninfected, the dominant strain will still be Delta.
②
The vast majority of people infected with Omicron present with typical flu-like symptoms that mainly affect the upper respiratory tract and are indistinguishable from influenza and the common cold. Without antigen or nucleic acid testing, it has become difficult to distinguish between neocoronavirus, influenza virus or other rhinovirus or coronavirus infections that cause the common cold. The proportion of asymptomatic infections and mild cases of Omicron is significantly higher, accounting for more than 99.5% of total infections.
③
Neocoronavirus disease is a self-limiting, self-healing disease. Now for the vast majority of people, 99.6% or more, it is self-limiting and self-healing.
④
It is not that the vaccine is completely ineffective, it is that the vaccine on the one hand can reduce infection, and on the other hand, even if it does not prevent infection, it can play an important role in preventing serious illness and reducing retransmission of the virus to others. However, we are used to seeing the effect of vaccines as all or nothing, either preventing infection completely or completely as if no vaccine was given, and many reports and even expert interpretations give the wrong impression of not properly recognizing and understanding the multiple protective effects of vaccines.
⑤
Looking at the data of this year’s epidemic in Hong Kong, if one shot of the vaccine is not given, the mortality rate is 2.32%; if two shots of Coxin are given, it is 0.36%; two shots of Fupirtide, it is 0.06%, that is, six out of ten thousand; if two shots of Coxin plus one shot of Fupirtide are mixed, it is 0.04%; if three shots of Coxin are given, it is 0.14%, which is very close to the mortality rate of influenza; four shots of Coxin, it is 0.11%.

Up to now, the new coronavirus has existed for almost three years, we have developed from the beginning of the nucleic acid test to the current antigen test, are greatly convenient for the nationals to carry out the new coronavirus test, our company currently has the most common nucleic acid test swab on the market, can be stored at room temperature virus samples, as well as the new coronavirus antigen test reagents, 15 minutes to produce results, simple sampling.
Our company is equipped with PCR and nucleic acid detection equipment specializing in the detection of Neocoronavirus, and a 96-channel nucleic acid extraction instrument greatly accelerates the detection speed! Contact us if you need.
