China News Service, May 18 (Xinhua) According to the "Shanghai Release" WeChat public account, at the press conference on Shanghai's epidemic prevention and control work held on the morning of May 18, Zhao Dandan, deputy director of the Shanghai Municipal Health Commission, pointed out that the city is currently It is in the stage of consolidating the achievements of the clearing and tackling. Although the social clearing has been achieved, the risk of finding positive infections among the risk groups still exists, and the pressure to "reduce new growth and prevent rebound" is still great.

If there are sporadic new positive infections, we need to strictly control the epidemic, do a good job of epidemiological investigation, and carry out emergency response work quickly.

  Zhao Dandan introduced that on May 17, Shanghai added 96 new confirmed cases of new coronary pneumonia and 759 local asymptomatic infections.

Of the 96 local confirmed cases, 40 were found in closed-loop isolation and control, and 56 were asymptomatic infected patients and turned into confirmed cases.

759 cases of local asymptomatic infections were found in closed-loop isolation control.

As of 24:00 on May 17, 218 severe patients and 63 critically ill patients had been treated in designated medical institutions.

  On May 17, 3 new local deaths were reported, with an average age of 69.7 years.

Three patients were complicated with malignant tumors or severe acute and chronic underlying diseases, including advanced gastric cancer, sudden cardiac death, dilated cardiomyopathy, total heart failure, severe hypertension, Parkinson's disease, and renal insufficiency.

Of the 3 deaths, 2 had been vaccinated against the new crown vaccine, and 1 had not been vaccinated against the new crown vaccine.

The immediate cause of death was the underlying disease or tumor.

As of 9:00 on May 18: A total of 911,343 close contacts in Shanghai have been investigated for this epidemic, all of which have been put under control.

  According to Zhao Dandan, yesterday, 274 local confirmed cases in Shanghai were discharged from hospital, and 3336 asymptomatic infected persons were released from centralized isolation and medical observation.

  Zhao Dandan mentioned that in the recent stage, we have continued to carry out "antigen + nucleic acid" combined screening based on the division of the three regions.

According to the screening results, on May 17, the city was divided into 3,435 closed control areas, involving a population of about 790,000 people; 16,108 control areas, involving a population of about 2.71 million; prevention areas of 52,600, involving a population of about 19.8 million people.

  Zhao Dandan pointed out that the city is currently in the stage of consolidating and clearing the achievements. Although the social level has been cleared, the risk of finding positive infections among risk groups still exists, and the pressure to "reduce new growth and prevent rebound" is still great.

If there are sporadic new positive infections, we need to strictly control the epidemic, do a good job of epidemiological investigation, and carry out emergency response work quickly.

  First, the word "fast" needs to be highlighted.

Once there is a positive infection in society, we must adhere to the fast system, coordinate the "city-district-community" three-level transfer team, carry out epidemiological investigations as soon as possible after receiving the report, and strictly implement the "2+4+". 24" work requirements, that is, the flow dispatch team arrives at the scene within 2 hours, completes the core information of flow dispatch within 4 hours, and initially checks the basic situation and completes the flow dispatch report within 24 hours.

  The second is the need to achieve a "quasi" word.

Relying on the emergency command system of epidemiological investigation, give full play to the role of the "three public (work)" collaborative working mechanism of public health, public security, and industry and information technology, combine on-site investigation and big data information, conduct comprehensive analysis, scientific research and judgment, check activity trajectories, and identify risks Crowd, reasonably determine the close contact and the close contact, so that "everyone should be checked, judged, and no one should be missed."

  The third is the need to implement a "tube" word.

Strictly implement various management and control measures, first of all to "transfer as much as possible", contact the city and district transfer departments as soon as possible after positive infection is found, and complete the positive results in the fastest time and the highest efficiency under the premise of ensuring safety. Transfer of infected persons.

For the close contacts who have been checked and determined, "should be isolated as much as possible, and should be isolated quickly" to block the risk of transmission to the greatest extent.

For the important places or key areas involved, risk investigation and control shall be carried out in a timely manner.

At the same time, combined with environmental testing, laboratory virus gene sequencing, etc., to do a good job in tracing the source of the epidemic.

  Zhao Dandan expressed the hope that citizens and friends will continue to cooperate and support the work of disease control and epidemic disposal, provide relevant information truthfully and accurately, implement isolation and control measures in a timely manner, and stop the spread of the epidemic more quickly.

This is to protect oneself, protect family members, and protect others, and it is also a contribution to the recovery of normal life in Shanghai as soon as possible.
