Chinanews.com, May 14th. He Qinghua, the first-level inspector of the National Health Commission's Disease Control Bureau, said on the 14th that the current study has not found any problem about the mutated strain that may lead to immune escape.
The State Council's joint prevention and control mechanism held a press conference on the 14th on the "foreign prevention import" and vaccination situation.
At the meeting, a reporter asked questions and said that recently it has been noticed that some cities have imported confirmed patients from India who have been infected with the mutated new crown virus. The WHO also released a message a few days ago that the epidemic in India is moving forward. Proliferation in neighboring countries, what are the current arrangements for foreign import defense?
In addition, experts in India also said that highly variable viruses may cause immune escape and infectious risks. What are the characteristics of the mutant viruses discovered this time?
What special prevention and control measures does my country currently have against the mutated virus in India?
He Qinghua said that at present, the global epidemic situation is still quite severe and complicated, with virus mutation showing three characteristics.
First, the mutation of the new coronavirus is generally accelerating. The data reported by the WHO shows that the frequency of mutation has gradually increased from 0.1 per thousand to 1.3 per thousand.
The second is that the number of countries with variants is increasing. The variants of the United Kingdom have been found in more than 130 countries and regions, the variants of South Africa have been found in 80 countries and regions, and the variants of Brazil have been found in 45 countries and regions. Find.
In particular, the newly emerged variant of India has attracted widespread attention from the international community, and the existence of this variant has been found in at least 44 countries and regions.
Third, with the continued spread of overseas epidemics, the emergence of new mutant strains cannot be ruled out.
Regardless of whether the virus mutates, becomes faster, or increases, my country has the ability to monitor imported mutant strains. At present, my country has detected mutant strains in Britain, South Africa, Brazil, and India.
He Qinghua pointed out that in terms of foreign defense import, we must continue to insist on "personal defense" and strengthen in five aspects.
The first is to strengthen the joint prevention and control of immigrants. The health and quarantine of immigrants, especially those from India and countries with high epidemics around my country, shall be strengthened, and centralized isolation shall be carried out to isolate the immigrants from the place of entry to the destination community Closed-loop management of the whole process.
Before the end of the 14-day quarantine, the departure place must promptly push the information of the quarantined person to the destination, and make a "point-to-point, person-to-person" handover. The immigration personnel are required to take personal protection during the journey. , Strictly implement seven-day home health management.
The second is to strengthen the nucleic acid testing of entry personnel, requiring entry personnel to collect nasopharyngeal swab samples for nucleic acid testing during isolation. Among them, two samples should be collected for nucleic acid testing on the 14th day, using two different reagents. In principle, two different reagents should be used. Testing agencies carry out testing to ensure the quality of our nucleic acid testing.
The third is to strengthen physical defense work.
Increase the inspection, quarantine and disinfection of imported goods from relevant countries, especially the outer packaging of cold chain foods, and strengthen regular nucleic acid testing of imported cold chain foods and employees.
The fourth is to strengthen the monitoring of mutant strains, carry out virus gene sequence determination in all cases, strengthen virus mutation tracking research, and timely assess risks.
Fifth, it is necessary to strengthen the import prevention capabilities of border ports. The focus is on land border ports that have been opened to ensure that all capabilities are in place in accordance with the standards for epidemic prevention and control capabilities.
He said that the current research has not found the problem that the mutated strain may lead to immune escape.Keywords:
