The State Postal Administration recently issued a notice requiring postal administrations at all levels to promote local governments to unseal the closed postal express infrastructure in an orderly manner as soon as possible if it meets the unsealing conditions, and to give priority to unsealing the delivery of epidemic prevention materials, livelihood materials and important production and living materials according to procedures. The notice requires that the epidemic prevention and control measures in risk areas and high-risk posts should be adjusted and implemented. The prevention and control measures for the "high and low" risk areas shall be implemented accordingly for the prevention and control of industrial epidemics within the "high and low" risk areas designated by the local government; The management measures for front-line operators who directly contact with overseas personnel, international mail express and other high-risk posts after completing closed-loop operations shall be adjusted accordingly. We should implement the "one enterprise, one policy" epidemic prevention and control mechanism. All postal express enterprises further improved the enterprise epidemic prevention and control mechanism, formulated the epidemic prevention and control work plan and disposal plan of the enterprise headquarters, and guided various production workplaces to formulate epidemic prevention and control work plan and disposal plan. We should focus on strengthening the management of key links, places and personnel. The relevant requirements on regular nucleic acid testing for express delivery practitioners shall be strictly implemented. It is necessary to strengthen the management of employees, including outsourcing personnel and drivers and passengers of freight cars in other places, and pay attention to the health monitoring and identification registration of temporary outsiders. We should improve our ability to handle emergencies. Postal administration departments at all levels should strengthen the response to and disposal of sudden epidemic situations in the industry and improve the ability to respond to and dispose of sudden epidemic situations. All postal express enterprises should guide all kinds of production and operation sites to formulate internal isolation management plans under temporary closed control, and quickly implement them in case of epidemic. All mail express processing centers should avoid the practice of "sealing off" foreign trucks. On the basis of good prevention and control, they should provide independent rest areas and necessary living services for drivers and passengers of foreign trucks. (Liu Xinshe)
