Rumors such as "there are confirmed cases in XX, I saw people in protective clothing disinfecting" and "XX is closed, there should be a new crown accounting for the rapid detection of confirmed cases" have been popping up on the internet and in WeChat groups. What's more, there is actually a strong word to lay out the track information of "new crown nucleic acid rapid test confirmed personnel".
Is this the legendary folk who have their own experts? The epidemiologists hiding in the folk?
I want to tell you: many of the information forwarded by the circle of friends is not true, during the epidemic, all our news should be subject to the official announcement, do not cause panic because of small news. If you find any inaccurate gossip, you can advise the publisher or even report it to the local public security bureau.
Is the presence of staff in protective clothing carrying out work in some neighborhoods and shopping malls that there is a confirmed case of Nucleic Acid Rapid Test for New Crest?
No! The presence of personnel in protective clothing in neighborhoods and shopping malls may be a routine disinfection of the premises. Neighborhoods and shopping malls are high-traffic areas where there is a higher risk of virus dispersion. Disinfection of these places is an important part of outbreak prevention and control.
Is a site sealed by staff in protective clothing that has a positive rapid test for Nucleic Acid in a new crown case?
No! There are many possibilities for this situation, such as personnel returning from a medium to high risk area to be quarantined at the site, or the discovery of a confirmed New Coronavirus Rapid Test case or a close contact of a suspected case, and the subsequent need for related environmental sample collection, epidemic prevention and disinfection, and other epidemic prevention work.
From the new crown nucleic acid rapid test confirmed cases strolled back to the mall, it must be a close contact?
Not necessarily! The determination of whether a person is a close contact is based on the following two aspects: first, whether there is close contact at close range, and second, whether to wear effective protection. In the mall, if people pay attention to keep a distance from others and wear a good mask throughout the regulation will not be judged as a close contact.
If I have been in contact with a patient who has been diagnosed with Nucleic Acid Rapid Test in the same place, and the Nucleic Acid Rapid Test is negative, can I be sure that I am not infected?
Not necessarily! Currently, the rapid NNA test uses nasopharyngeal swabs for nucleic acid collection, and the virus replicates mainly in the upper respiratory tract. However, the results of the New Crown Nucleic Acid Rapid Test are affected by many factors, whether the sampling is standard, whether the concentration of detoxification reaches a certain level, whether the sample is contaminated, etc. will affect the results of the nucleic acid test.
The current fluorescence quantitative PCR method used in the new crown nucleic acid rapid test, mainly through four stages: sampling - sample pretreatment - nucleic acid extraction - nucleic acid amplification and analysis. Any step in these four steps that is not standardized enough may result in a false negative.
To test whether you are infected, you have to perform multiple rounds of rapid nucleic acid testing for new crowns. The efficiency of the rapid nucleic acid test for new coronas has now increased dramatically due to continuous technological advances.
