Silent management usually lasts about 5-7 days, depending on the actual situation. If the prevention and control effect is good, it will not be extended, otherwise, it will be extended.

what is silent management is static management. Let the whole city temporarily calm down and stop, and at the same time carry out large-scale nucleic acid testing, screen out potential infected people at the fastest speed, cut off the spread chain of the epidemic, and let the control measures run faster than the virus spread.

Silent management is the static management of the whole region, and the epidemic prevention and control area is kept silent, so that it can't enter the outside, can't leave the inside, and can't move inside. Except for medical treatment, front-line protection and nucleic acid testing, all staff members are not allowed to leave home, accept express delivery or buy group.

Control cannot be replaced by "silence":

All localities should speed up the accurate epidemiological work, and the prevention and control of epidemic situation cannot be simplified, risk areas cannot be demarcated in a large scale, and control cannot be replaced by "silence".

it is necessary to accurately define the middle and high risk areas in time, take resolute control measures in time, and make dynamic adjustments according to the changes in the epidemic situation. Those who meet the conditions for unsealing should be unsealed in time to facilitate people's lives and travel. Schools, restaurants and other units outside the risk area should strengthen epidemic monitoring, resolutely avoid "one shut down" and minimize the impact of the epidemic on economic and social development.
