Recently, there was a COVID-19 epidemic in Bangladesh, and the current prevention and control situation is very grim. On the afternoon of April 8, the Chinese Embassy in Bangladesh and the Shanghai Foreign Affairs Office jointly organized a video conference on the fight against the COVID-19 epidemic. Coordinated by the Shanghai Municipal Health Commission, the leader of the Shanghai COVID-19 medical treatment expert group, affiliated to Fudan University Zhang Wenhong, director of the Infection Department of Huashan Hospital, attended the meeting.
During the meeting, Bangladesh asked: What is the spread of the COVID-19 virus? “We heard that the spread of this virus is 2-3, that is, a person infected with 2-3 people is actually much smaller than other infectious diseases. So how to explain that since the spread is small, but spread so fast?”
Zhang Wenhong explained that the early thought that the spread of the COVID-19 virus was between 2-3. Now everyone sees that the infection rate of the COVID-19 virus is far faster than that of SARS. I think the spread should be close to 4. ”
Why spread quickly?
Zhang Wenhong said that the proportion of asymptomatic infections of COVID-19 virus is 36-38%, “the spread of this group of patients is also very strong.” And the incubation period of the COVID-19 virus is 1-14 days, which is also longer than SARS, making it very easy to spread. “This disease is unlikely to end in a short period of time. German experts say they are prepared to fight the two-year war against epidemic. American experts told me that they have not returned before the epidemic. The overall situation is still not optimistic. I hope the vaccine will arrive soon.”
