As winter is about to enter, will the new crown epidemic make a comeback?
What issues should be paid attention to in preventing and controlling the epidemic in winter?
"For the aggravation of the new crown epidemic that may be encountered in the winter of the battle, containment strategies, detection strategies, and vaccine strategies can be used." On October 21, at the first Southeast Science and Technology Forum in Fujian Province, Wu Zun, chief epidemiologist of the Chinese Center for Disease Control and Prevention Professor You gave a special report on "New Crown Epidemic Situation and Prevention and Control Strategies", and used popular and vivid language to help everyone explain their doubts.
"The global epidemic is still not optimistic." Wu Zunyou initially judged that in the future, the global new crown epidemic will continue to be prevalent at a high level, and it will increase in winter on the basis of high levels.
"Even if the global new crown pneumonia epidemic intensifies in winter, China will no longer have a serious situation like Wuhan." Wu Zunyou believes that in the past 9 months, there have been intermittent clusters and sudden outbreaks in my country, and there may be minor outbreaks in the future. Large-scale and sporadic epidemics.
Three strategies of containment, testing, and vaccines can be used for the aggravation of the new crown epidemic that may be encountered in the winter of the battle.
Wu Zunyou suggested that for China, the main focus of prevention and control is foreign input, one is to prevent people and the other is to prevent materials.
The normalization of prevention and control in winter still needs to remind ordinary people to maintain a sense of protection, such as washing hands frequently, maintaining social distance, and ventilating at home.
Wear a mask when you go to key places, especially places with poor ventilation.
Wu Zunyou emphasized that once symptoms such as fever and headache occur, you must seek medical treatment in time and never delay.
Because of this, it may be caused by the common cold and pneumonia, or it may be an early case of new coronary pneumonia.
At the same time, health systems at all levels must strengthen the sensitivity of epidemic surveillance and raise the awareness of prevention of grassroots medical staff.
“Early consultation is not only conducive to timely diagnosis, treatment and recovery of patients, but also conducive to the first time detection of the epidemic. It is very important for the overall epidemic control.” Wu Zunyou said, taking the outbreak of the outbreak in the Beijing Xinfadi agricultural product wholesale market as an example According to calculations, if the first case in Beijing’s newly-occurring area is detected three days later, the number of epidemic cases may exceed 1,000, one week later, the number of cases may exceed 10,000, and two weeks later, the number of cases may exceed 100,000.
From the perspective of vaccine strategy, Wu Zunyou believes that it can be considered from two aspects. One is the application of vaccines to prevent respiratory infections, such as pneumonia vaccines and flu vaccines, to reduce the incidence of respiratory infectious diseases in winter and prevent running out of medical resources. The second is a targeted new crown virus vaccine. Some key populations and high-risk groups in special industries should give priority to new crown vaccination.
