It is necessary to make every effort to check and isolate, and rely on Community Grid Management to do a good job in organization and mobilization, so as to ensure that no one is missed. It is necessary to strengthen the supervision of the whole process of nucleic acid testing, strengthen the training, guidance, supervision and evaluation of on-site sampling, and effectively improve the quality of nucleic acid sampling and testing. It is necessary to do a thorough and meticulous job in tracing and investigating the source of the epidemic. The "three public officials (workers)" should form special teams and work closely together to clarify the transmission chain as soon as possible, lock in the source of the outbreak, and plug the loopholes in a timely manner. It is necessary to strengthen the prevention and control of key places, assess the potential risks of industries with dense personnel and closed environment one by one, promote the release of safety and restore the production and living order.
