Chinanews Client Beijing February 28th (Zuo Yukun) On the 28th, Wu Yuanbin, director of the Department of Social Development and Science and Technology of the Ministry of Science and Technology, said at a press conference that, so far, the research conclusions show that respiratory droplets and close contact transmission are still Is the main transmission path of the new crown virus. During the research, some teams also detected the new crown virus from stool samples of patients with new crown pneumonia, which also suggests that there is a certain risk in fecal-oral transmission, but further research is needed to confirm the transmission capacity and conditions.
Aiming at the problem of aerosol transmission, the Institute of Laboratory Animals of the Chinese Academy of Medical Sciences has also conducted corresponding transmission experiments. It has also been suggested that aerosol transmission must meet the three conditions of closed space, long time and high concentration of virus at the same time, only under extreme conditions. The possibility of aerosol transmission. For ordinary people, the possibility of transmission in a well-ventilated daily life environment is very small, and there is almost no risk of aerosol infection.
