It was learned from the press conference on the prevention and control of COVID-19 held in Beijing on the afternoon of 27th that with the change of the epidemic situation, Beijing will continue to optimize community prevention and control measures, do its best to ensure service and minimize the impact on people's lives. Wang Daguang, the head of the Community Prevention and Control Group Office of the Leading Group for the Prevention and Control of COVID-19 in Beijing, introduced that according to the needs of the epidemic prevention and control, the temporary control measures taken, such as tracing the source of the current epidemic, checking the positive and chasing the positive, should be announced to the public at the first time, and explanations should be made. The temporary control time should not exceed 24 hours in principle. Beijing strictly implemented the ninth version of the prevention and control plan and optimized 20 measures for epidemic prevention and control, and scientifically defined risk areas. High risk areas are generally defined by units and buildings. In case of unclear epidemic transmission risk or widespread community transmission, the scope of high-risk areas can be appropriately expanded after strict assessment. Wang Daguang pointed out that it is strictly prohibited to take measures such as hard isolation and hard enclosure to block fire passages, unit doors and community doors. In high-risk areas, "stay at home and provide door-to-door services" shall be implemented. For medical treatment, emergency escape, rescue and rescue, etc., it is necessary to ensure smooth channels for going out. For those that meet the unsealing conditions, "all solutions shall be solved". Wang Xiao'e, member of the Party Committee of the Beijing Municipal Health Commission and spokesman of the press, said that Beijing would, according to the situation of epidemic prevention and control, strive to build a medical security system for key epidemic related personnel with "clear needs, open channels, detailed measures and quick response", and designate hospitals with complete clinical specialties and strong comprehensive rescue capabilities as designated hospitals and designated fever clinics for epidemic risk related personnel in the region. Fever clinics and emergency departments provide 24-hour services, Specially assigned persons are responsible for the 24-hour reception and referral of key epidemic related personnel, opening green channels, simplifying the process, shortening the stay time of personnel in the hospital, and providing convenience for community staff to centrally prescribe drugs. Zhao Weidong, deputy director of the Beijing Municipal Bureau of Commerce, said that at present, the vegetable supply in Beijing has shifted to the winter supply mode, and the vegetable supply in the south has increased. The relevant units should make good arrangements for commodity distribution and transportation. Recently, the supply of vegetables and other necessities in Beijing has been sufficient and stable. In the past week, the average daily market volume of vegetables in the major agricultural product wholesale markets in Beijing was 21700 tons. The supply of vegetables was sufficient and the transaction was stable. The wholesale price decreased by 25% and the retail price decreased by 20% year on year. The purchase and sales of grain and oil market are orderly and the inventory is sufficient. From the retail side, Beijing supermarket stores, direct marketing direct supply and fresh food e-commerce enterprises have stocked up 3 to 5 times of their usual quantity. Affected by the epidemic, some stores were temporarily closed due to epidemic prevention and control. However, through quick inspection and quick release and other work measures, they can basically resume operation quickly. Enterprises also maintain the stability of the overall supply of the terminal by timely deployment of staff, increase of transport capacity, etc. (Outlook New Times)
