After being infected with Omicron, the physical symptoms are: slight muscle pain, some people will have itchy throat or cough, and the whole body will be weak. Most people can gradually improve with their resistance, and there are few sequelae. Judging from the cases in South Africa, most infected people under the age of 40 have mild symptoms, and some even have no symptoms. Generally speaking, it is less toxic than biota strain and hardly induces the failure of taste or smell.

First, the mystery can escape the human immune system and be more contagious?

Omicron escaped from the human immune system because of the mutation of COVID-19's spike cells, causing people to be infected by COVID-19 virus unconsciously. Medical research shows that Omicron has certain concealment and can attack the human respiratory system. Fortunately, according to the existing research, the toxicity of Omicron to human body has not increased, and patients with mild symptoms still account for the majority.

Second, patients with Omicron will have mild throat itching, slight muscle soreness, slight cough and other symptoms, which will be considered mild in medicine?

Most patients infected with mysterious Crohn's disease can survive the virus infection period by their own resistance. It rarely develops into a serious disease, and the situation of transferring to hospital for infusion will be much reduced, and there will be almost no failure of smell or taste. The development law of Omicron is more like the general law of respiratory diseases. In the process of transmission, the toxicity of the virus gradually weakens, and human beings are expected to defeat this virus. ?

3. Want to prevent Omicron infection, or should we popularize vaccination and reduce clustered infection?

China is about to complete the group immunization barrier, which is good news for the people. However, the vaccination rate in backward countries abroad is still relatively low, so it is difficult to completely eliminate this virus. We still have to take epidemic prevention measures to minimize the possibility of infection around the mysterious Keron. ?

So, do you think that Omicron is a threat in China?
