Zhang Wenhong: Vaccine research and development accelerates scientific and technological development to increase confidence in controlling the epidemic

BEIJING, Nov. 16 (Xinhua) -- Zhang Wenhong, director of the infection department at Huashan Hospital affiliated with Fudan University in Shanghai, pointed out that the current rapid pace of vaccine research and development shows that human scientific and technological forces are constantly developing, so he has strong confidence in the eventual control of the new crown epidemic. He also reminded that attention should also be paid to the new coronavirus.
Zhang Wenhong recently gave an exclusive interview to China News Agency's "China Focus Face-to-Face" in Beijing.
on the issue of vaccine research and development of public concern, Zhang Wenhong said that after the emergence of a new infectious disease, vaccine research and development are in an emergency state of development, the speed will be accelerated. This research and development speed up, in the history of human infectious diseases
is the regular expedited research and development process, but now the technical force is better than before, so the research and development speed will be faster. This shows that human science and technology is constantly developing, it will only become faster and more accurate at an unimaginable rate. "That's why I have a lot of confidence that this new crown outbreak is finally under control."
Zhang predicts that the world will basically start getting vaccinated by the end of this year or early next year.
Referring to the topic of what people feel is "more and more asymptomatic infections and fewer deaths," Zhang said the rate of new cases is inconsistent with the rate of deaths, meaning that the global rate of new deaths is falling; It's easy to give the illusion that the virus isn't as toxic as it used to be.
he points out that the calculation model of the death rate is the key to the problem. Diagnostic capacity around the world is improving dramatically, and many asymptomatic people will be tested, resulting in many asymptomatic infections. In the early stage, the diagnostic ability can not cover asymptomatic people, so the early onset of severe illness, the death rate is naturally relatively high. Now asymptomatic people also go to test, the death rate will be very low, "this is normal, because you choose not the same population."
, the highest rate of death worldwide is among the elderly. This high-risk group has begun to protect itself. The death rate among young people is already low, and this global outbreak is characterized by infections among young people after social reboots, but their death rates are low.
third in the world, and since January, new crown rescue supplies around the world have been replenished. Prevention and control of the epidemic is the war, the better the logistical support, the more successful the war, the higher the success rate of the patient's rescue.
Zhang Wenhong also pointed out that seeing a phenomenon on the random guess its cause, is often wrong. For example, you're seeing a drop in death rates now, but if you're not in the health care system, it's easy to think that the virus isn't as bad as it used to be.
, Zhang Wenhong stressed that we still need to pay attention to the virus.
