Question: When will the new pneumonia epidemic prevention and control be effective? -Virology experts talk about epidemic prevention and control
Xinhua News Agency reporter
387 railway stations carried out temperature measurement and screening, increased epidemic prevention and control efforts in various places, and emergency deployment of various resources to support Wuhan ... In the Spring Festival holiday of the Gengzi year, a new coronavirus-infected pneumonia epidemic prevention campaign has begun. It is not difficult to prevent and control. When the prevention and control measures take effect, it has become a hot issue that people care about.
"Controlling the entry and exit of Wuhan personnel and less public access are good social measures." Wen Yumei, an academician of the Chinese Academy of Engineering and a professor of the Ministry of Education / Fujian Health and Medical Committee Key Laboratory of Medical Molecular Virology of Fudan University believes that it is adopted in the general population. After certain measures are taken, the epidemic situation should be able to be controlled step by step, and it needs a process. The number of confirmed cases now is because some people have been infected more than twenty days ago, and the measures now taken are to prevent possible secondary or tertiary infections in the future. Therefore, in general, the spread of the epidemic will decrease after about 20 days.
"Not everyone will be infected, and a small number of people will be infected." Wen Yumei said that the current measures will see results in more than 20 days, and I believe that the epidemic will be well controlled by then. During the epidemic of disease, the human body will inevitably produce immunity against the microorganism, the immune capacity of the population will increase, and the epidemic will eventually end.
Disease control and medical experts believe that as long as scientific control and accurate policy implementation, epidemic prevention and control will definitely be won. However, experts admit that there is a certain degree of difficulty in prevention and control, and the enemy cannot be underestimated.
Li Taisheng, director of the Department of Infectious Diseases, Peking Union Medical College Hospital, has been involved in the prevention and control of SARS since January 2003, and has a good understanding of coronavirus. In his view, pneumonitis infected by the new coronavirus does not progress as quickly as SARS.
"The average incubation period of SARS virus is 6 days, while the new coronavirus is 9 days, which makes it very difficult to prevent and control."
Li Taisheng said, according
to common sense, the shorter the incubation period of a virus, the stronger its virulence and the greater the number of pathogens. However, according to the data released now, the severity of pneumonia caused by the new coronavirus is not at all lower than that of SARS, which is very unusual.
Cao Wei, deputy director of the Department of Infectious Diseases, Peking Union Medical College Hospital, believes that from the case spread outside Hubei Province, the mortality rate of pneumonia caused by the new coronavirus infection is lower than that of SARS, with a large proportion of mild patients.
Since there are no typical symptoms during the incubation period and it is contagious, it brings certain difficulties to prevention and control.
Joint prevention and control is not only a matter for government departments and medical and scientific research institutions. Everyone's participation is the real "joint prevention and control." In a few days, the return passenger flow for the Spring Festival is coming. The large-scale movement of personnel has put forward new requirements for prevention and control.
Experts suggest that those who come back from Wuhan or have come in contact with Wuhan returnees should be isolated. Avoid contact with others during quarantine to prevent spreading the virus to family, colleagues, and friends.
Professor Bai Chunxue of the Shanghai Institute of Respiratory Diseases and the Institute of Respiratory Diseases of Fudan University believes that
"isolation" and "keep away" are also keywords for the prevention of infection with the new coronavirus. "If a virus carrier has two weeks without contact with other people, the threat posed by the virus will disappear a lot."
In his view, "isolation" and "away" should be done: not to go to the epidemic area; not to contact the people in the epidemic area, or even relatives who have been in contact with it; keep a distance with others, and it is best to wear a mask 3 meters away Above; avoid any social activities where possible.
Panic does not help defeat the disease. Wen Yumei said that it is necessary to face the epidemic scientifically and calmly, and take personal protection. "Do n’t think that your body is fine, do n’t wear a mask." At the same time, you do n’t need to panic too much. Coronaviruses have flooded into medical institutions, which not only caused an excessive medical burden, but also increased the possibility of cross-infection. "Severely ill patients often have other diseases of their own, and their immune function is abnormal. Most infected people have normal immune function and will gradually recover."
