In response to this round of epidemic in Tianjin, Zhang Boli, an academician of the Chinese Academy of Engineering, said that although the transmission relationship between the infected people that has been found is relatively clear, the source of the epidemic infection has not yet been identified, mainly because when the Ambi Kerong virus was found in Tianjin, it has been transmitted for at least three generations, which brings difficulties to the source of the virus.
Zhang Boli, an academician of the Chinese Academy of Engineering, said: "Now the traceability is still in progress, (related cases) have not crossed the border, and there is no contact with foreigners or people who have returned from overseas, so its source 'patient zero' cannot be found now, especially the omicron is very hidden, and the transmission is also very strong, so you can't find it, which means that there are many opportunities that they may still be spreading." ”
One of the characteristics of Aomi Kerong in tianjin's current round of epidemic is that the speed of human transmission is fast, but the symptoms of infected people are significantly reduced, and Zhang Boli does not agree with some people who regard it as a large cold.
Zhang Boli said, "It is not the same as the flu, in fact, very mild patients or discharged from the hospital have no symptoms, but after a few months there are some symptoms, why is this so?" I don't know. But we look at the current situation, do not wait passively, taking some drugs can improve symptoms, control the progression of the disease, the effect is still positive. ”
