On January 6, Zhang Boli, academician of the Chinese Academy of Engineering and honorary president of Tianjin University of Traditional Chinese Medicine, shared with netizens the key points of prevention, treatment and rehabilitation of the new coronavirus infection, and said that the smoke and fire will come back, be full of confidence.

Netizens are concerned: Why do you feel that the strains prevalent in the north are “more virulent”?

Zhang Boli said: “Based on the experience of these three years, we can not underestimate this virus. Many of its changes are within the predicted analysis, but there are also many unexpected things, especially in the clinical phenotype.” For example, in this discussion on “the northern strain is more virulent,” theoretically, the northern strain BF.7 is a mutation of the BA.5.2 that is prevalent in the south, and overall there is no fundamental difference between the two strains. However, symptomatically, differences do exist. Although we have not seen any more clinical reports, it is clear that “the symptoms are milder in the south and more aggressive in the north”, which is related to the strain on the one hand and the climatic differences between the north and the south on the other.

“Our knowledge of the virus is still far from enough, we must also strengthen the research.” Zhang Boli said we have a deep understanding of the new coronavirus infection law: three years of protection so that the level of social immunity is low, once released, the virus is transmitted too fast and the incubation period is short, it is easy to form a peak of infection. Therefore, areas that have not reached the peak should be prepared for a rainy day and do a good job of stockpiling drugs and other medical resources; areas that have reached the peak should do a good job of treating and rehabilitating persistent symptoms after turning negative, so that people can go back to normal life and work as soon as possible.

Netizen’s concern: How can I recover my health properly after “Yang Kang”? Can I work out?

Many infected people still have some persistent symptoms such as cough, weakness, panic and sweating after turning negative. Zhang Boli said that these are common symptoms after the conversion, and the conversion does not mean complete recovery. The patient’s body is still fragile or weak for a period of time after the conversion, the immune function is not fully repaired, and the respiratory tract and other organs may still be somewhat damaged. Therefore, during the 2-3 weeks or even longer after the conversion, it is important to take rest and pay attention to a light diet, as well as to take good personal protection. The recovery during this period is very critical. Physical exercise can be resumed gradually, but in moderation, slower and less overall, and with rest. The appearance of some persistent symptoms after turning negative, such as cough, weakness, panic, night sweats, etc., generally do not need to panic too much, 2 to 4 weeks, most people’s symptoms are reversible and recoverable, and those who really can not recover are very few. Taking some symptomatic herbs can improve symptoms and promote restoration.

Netizen’s concern: What should I do if I have a prolonged cough after “turning negative”?

In the interview, Zhang Boli shared 2 small remedies, one is to gargle with ice salt water. The simple way to do this is to add a little salt to the mineral water, so that you can taste a little saltiness. Put it in the refrigerator to chill, every morning and evening after brushing teeth to take it gargle, spit it out, then pour out a little, take a cotton swab dipped in scrubbing the nasal cavity. Zhang Boli said, this is not to destroy the virus, but to clean the throat environment, stimulate the activation of mucosal immunity, to prevent infection, reduce the symptoms of post-infection itchy throat, etc. beneficial. Another small remedy is to wash the orange peel, cut it into the size of a postage stamp, soak it in honey and bring it to hold when the throat is dry, itchy or dry cough. Honey orange peel in the mouth, itch and cough symptoms can also be reduced some.

Finally, academician Zhang Boli said, “I hope you will not be anxious and I wish you all a peaceful Chinese New Year to get through this wave.”
