As of 14:00 on January 12, Tianjin has reported a total of 137 cases of positive new coronavirus infection in this round of the epidemic, of which 76 are confirmed cases of new crown in Tianjin.
It is worth noting that this is also the first time that China has faced the indigenous epidemic caused by the mutant strain Omicron. In the public opinion and discussion, a saying spread: Omicron's symptoms are mild, equivalent to "big flu".
What are the facts? Hokkaido University Master of Neuroscience, a senior medical consultant of Sheng Nuo, Weibo Science Popularization University V Zhuang Shilihe interpreted this.
Zhuang Shilihe: Regarding the severity of Omicron's symptoms, the most accurate description I see should be: Less severe but NOT mild.
In New York, Boston and Chicago, the number of COVID-19 deaths has reached or exceeded its peak in the same period last year. Although considering the number of infections four or five times higher than that of the same period last year, the severe illness rate and case fatality rate after infection have now been reduced a lot, this does not mean that Omicron is mild after infection.

In my comment area, there are also many friends who have shared their personal experience of infecting Omicron, most of them are mild or asymptomatic, some are indeed similar to the common cold, but the throat is uncomfortable, after a few days, there is no fever and cough.
I think these are very important experiences to let more friends know what kind of symptoms people like "we" may have after infection. But note that most of these infected people are young and middle-aged people, all of whom have been vaccinated, and some people have even received three or four doses of vaccines, to a certain extent, the young body and the immunity generated after vaccination are helping them resist the virus.
In fact, even in Wuhan two years ago, when no one had been vaccinated, 80% of infected people were only mild or common when faced with the more pathogenic original strain. For most children and young and middle-aged people who have been vaccinated, weakened Omicron does not cause too serious disease, but it is different for the elderly, immunodeficient or un-vaccinated people.
So while it behaves more like an upper respiratory infection, Omicron is essentially a coronavirus, and it's not called "big flu."
And even if many people think that the flu is a trivial case, it causes more than 80,000 related over-deaths in China every year.
