The Delta strain is more human-friendly, heat-resistant, more transmissible and has a higher viral load than the New Guinea strain, making the situation more critical. When it first became prevalent in China, the Epidemic Prevention Committee changed the concept of close contacts for Delta virus, from "those who dined or communicated with the patient or the patient's family within 1 meter in the same space two days before the onset of the disease" to "those who dined or communicated in the same space, the same unit, the same building, or the same building.
In the same space, in the same unit, in the same building, in the same building, and in the four days before the onset of the disease, those who were in close contact with the patient were all close contacts. The only way to deal with the Delta virus is to get ahead of it and cut off its path before it spreads widely.
The Guangzhou government's approach to the outbreak was to use the "run" strategy - to cut off the possible transmission path of the virus and to conduct rapid screening with the new crown nucleic acid test in time for the outbreak.
When conducting the screening, Xu's close contacts were classified into a risk level, and the close contacts with the closest contact and highest risk of infection were subjected to epidemiological investigation according to suspected cases, with each case followed by a group of dedicated flow transfer personnel to screen and centrally isolate their close contacts and sub-close contacts, and to control the key places associated with them.
One check ten, ten check hundred, new crown nucleic acid rapid test should be detected, multiple rounds of repeated new crown nucleic acid rapid test, before the widespread spread of the virus, first to kill the spread of possible. This is one reason why some places that are not directly related to the East China Sea Building also need to do the corresponding preventive and control measures.
Although the current situation of epidemic prevention and control is better, and the preventive and control measures in the face of an outbreak are very rapid, vaccination is still the most economical and effective means of prevention and control.
In addition to vaccination, Nucleic Acid Rapid Test (NAR) is also an indispensable tool for prevention and control. As the "gold standard" for Nucleic acid testing, it is still the key to prevention and control of the epidemic. In addition to the large-scale Nucleic acid testing required by the government, personal health testing is also necessary to minimize participation in congregate activities, avoid taking public transportation when symptoms appear, and if there is a duplicate track with a confirmed patient and their close contacts, it is important to avoid taking public transportation. If there is a duplication of trajectory with the diagnosed person and their close contacts, self-testing can be performed at the local hospital.
There are currently two types of testing: multiplex testing and single testing. If the risk of exposure is low, choose the more economical multiplex test; if the risk of exposure is too high, choose the single test and proactively report it to your hospital or local government.
