So far, this round of epidemic has affected at least 20 provinces. Gene sequencing and flow tracing showed that this round of epidemic was caused by multiple unrelated overseas input sources. "The situation of prevention and control is grim and complex due to the superposition of winter and spring seasonal factors." the joint prevention and control mechanism of the State Council recently made a study and judgment on the trend of the epidemic situation in some areas, emphasizing that we should unswervingly adhere to the general strategy of "external defense input and internal defense rebound", and "find and extinguish the epidemic together", so as to consolidate the hard won achievements of prevention and control. The global epidemic is high, and respiratory infectious diseases have entered a high incidence period "The epidemic situation in Heilongjiang, Hebei, Henan, Jiangxi, Sichuan, Chongqing, Liaoning and Dalian is still developing, so we need to pay close attention to the trend of the epidemic situation," said Wu Liangyou, deputy director of the disease control bureau of the National Health Commission. According to reports, judging from the current situation, community communication in Inner Mongolia, Beijing, Guizhou, Shandong and other provinces has been basically controlled; The epidemic situation fluctuates at a low level in Gansu, Qinghai, Ningxia and Dehong, Yunnan, but the risk of epidemic overflow is low. At present, the global epidemic is still at a high level, and the variation and spread of the virus is accelerating. As the weather turns cold, respiratory infectious diseases enter a high incidence period. These factors continue to put pressure on domestic epidemic prevention and control. "The situation of epidemic prevention and control this winter and next spring is complex and severe." Wu Liangyou said that the National Health Commission will pay close attention to the relevant progress, work with relevant departments to guide all localities to implement the deployment of joint prevention and control mechanism, continue to strengthen epidemic monitoring, and strengthen the epidemiological investigation of cases and control personnel. At the same time, strictly implement the control measures for risk areas and risk personnel, strengthen the management of medical institutions and centralized isolation points, strictly prevent the risk of secondary epidemic, promote the timely implementation of various measures, and effectively control the epidemic as soon as possible. Strict prevention and control at land ports and re reinforcement of epidemic defense lines According to the results of tracing the source of flow regulation, since the epidemic in Wuhan, there have been more than 30 local epidemic situations in China, all caused by overseas imports. In this round of epidemic, confirmed cases of truck drivers engaged in cross-border transportation appeared in some land port cities, highlighting the complex situation of prevention and control in port cities and border areas. It is reported that in the next step, the joint prevention and control mechanism will continue to increase support for epidemic prevention and control, economic and social development and livelihood security of port cities, and urge all border ports, especially land ports, to strictly and tightly implement various prevention and control measures. Wu Liangyou said that we should strictly control entry, prevent illegal entry, strictly manage personnel, strictly manage imported goods, improve the sensitivity of detecting epidemic situations, improve the sensitivity of detecting proliferation risks, further improve the level of epidemic prevention and control, and strengthen the epidemic defense line. "The State Administration of immigration is taking precise measures to prevent and control the border according to the new situation and characteristics of the epidemic this winter and next spring," said Liu Haitao, director of the border inspection and Management Department of the State Administration of immigration. "On the one hand, the competent department of transportation should make every effort to do a good job in epidemic prevention and control, on the other hand, it should effectively ensure the stability and smoothness of the international logistics supply chain," said Zhou Min, deputy director of the emergency office of the Ministry of transportation. We will continue to adhere to strict prevention and control measures when the epidemic situation is found and put out It is reported that tourism, wedding banquet and other gathering activities are important factors causing the large-scale spread of the epidemic. In this regard, Wu Liangyou said that for exhibitions, forums and other gatherings, we should strictly implement the responsibility for epidemic prevention and control in accordance with the principle of "who will be responsible for hosting, who will be responsible for approval", and try to hold them online if they can be held online, so as to reduce the risk of epidemic transmission caused by personnel gathering and mobility. Wu Liang also called on the broad masses to actively cooperate with the national prevention and control measures, minimize travel during the epidemic, consciously control the number of dinner parties, weddings and funerals and other activities, minimize participants and do little. "Over the past year, we have established a working mechanism combining normalized and accurate prevention and control and emergency response to local epidemics, and once an epidemic is found, we will completely put out an epidemic." Wu Liangyou said that we will continue to adhere to strict epidemic prevention and control measures, build a solid barrier for "external defense input and internal defense rebound", and consolidate the hard won achievements in prevention and control.
