China News Service, Shanghai, May 4 (Reporter Chen Jing) At the press conference on the prevention and control of the new coronary pneumonia epidemic in Shanghai held on the 4th, Zhao Dandan, deputy director of the Shanghai Municipal Health Commission, said that after the recent phase of "antigen + nucleic acid" Combining screening and corresponding prevention and control measures, the effect of prevention and control has become increasingly apparent, the population of the closed and controlled areas has gradually decreased, and the population of the prevention areas has increased day by day.
He revealed that from May 1st to 3rd, a total of 192 positive infections were found in the screening of relevant risk groups, accounting for 1.07% of the new positive infections in the three days.
On May 3, Shanghai was divided into 12,435 closed control areas, involving a population of 2.39 million; 20,808 control areas, involving a population of 5.19 million; and 47,861 prevention areas, involving a population of 15.78 million.
On the 3rd, Shanghai added 260 new local confirmed cases of new coronary pneumonia and 4,722 local asymptomatic infections; 16 new local deaths, with an average age of 82.9 years old.
All 16 patients had severe multi-organ chronic underlying diseases and malignant tumors, and none of them had received the new crown vaccine. The direct cause of death was advanced tumors or underlying diseases.
At present, there are 486 severe patients and 95 critically ill patients receiving treatment in designated medical institutions.
After being discharged from the hospital (cabin), "Fuyang" has always been a topic of public concern.
In this regard, Zhao Dandan introduced that practical research has proved that in convalescent patients with new coronary pneumonia, when the nucleic acid detection Ct value is ≥35, live virus cannot be isolated from the sample, which means that such patients are no longer infectious.
After being discharged from the hospital (cabin), those infected with the new coronary pneumonia virus are not included in the community screening objects, and they do not need to undergo new coronavirus nucleic acid testing or antigen testing within 6 days of home health monitoring, that is, they do not participate in community-organized nucleic acid testing and antigen testing during this period. .
On the seventh day, a nucleic acid test will be carried out, and the territorial area will arrange a special car to transfer it to a public medical institution for testing, or a medical staff will come to the public medical institution to take samples and send it to a public medical institution for testing.
If the nucleic acid detection Ct value is less than 35, it should be immediately transferred to a designated hospital or makeshift hospital for isolation management according to regulations.
Zhao Dandan said that the person's test results do not affect the "three districts" division of the building and the community.
