When nucleic acid testing, these misunderstandings should be avoided

Starting at 0:00 on April 16, our city will implement 4-day temporary social control measures across the city. During the control period, three large-scale nucleic acid testing will be carried out, the last one starting on April 19. Disease control experts reminded that nucleic acid testing can detect infected persons as early as possible and is an important means of epidemic prevention and control. Nucleic acid testing during the control period is very important and necessary, and the general public must actively cooperate and investigate thoroughly.

Recently, the reporter found that Many citizens did not take off their masks during nucleic acid testing and sampling, but pushed the masks upwards to expose their mouths. Experts warn that this approach is not advisable. First of all, the nucleic acid test must expose the mouth. After the mouth is exposed, if the seal is not very good, it is not of great practical significance to wrap the nose irregularly. Secondly, in the process of pushing the mask up by hand, it may cause the skin of the hands or face to come into contact with the outside of the mask, so that the outside of the contaminated mask can come into contact with its own skin, so this method is not recommended for nucleic acid testing. .

During nucleic acid testing, to remove the mask correctly, you must first grab the ear straps to remove the mask, and avoid touching the outside of the mask with your hands. Properly keep the removed mask to avoid contaminating the inside of the mask. Wear it in time after the test. If you touch or contaminate the inside of the mask, you should replace it with a new one in time. In daily life, we also remind everyone not to pull the mask to the chin, neck, etc. for the convenience of speaking and eating, and do not hang the mask on the arm to contaminate the inner layer of the mask.

A citizen asked, It only takes a few minutes to go downstairs to do the nucleic acid test. Do I need to throw away the mask after the nucleic acid test? In this regard, experts responded that it is recommended to throw them away. How to throw away the worn masks and where to throw them are particular. Before going to the nucleic acid test, it is recommended to prepare a spare mask. When queuing up for nucleic acid testing, you must wear a mask correctly. When the staff takes out the sampling cotton swab to prepare for sampling, the person being sampled will take off the mask, hold the ear strap of the mask with both hands, and put on the mask immediately after sampling and leave. .

When the mask is found to be contaminated, it is recommended to replace the spare mask immediately. Throw it into the “dedicated bucket for discarded masks” set up at the sampling point. If you do not have a spare mask, it is recommended not to reuse the mask you take off after returning home. It needs to be sealed or disinfected and then thrown into the “dedicated bucket for discarded masks” set up in the community, or put in a plastic bag and sealed and discarded into other garbage collection containers.

Used masks cannot be thrown away casually. According to the “Guidelines for the Use of Pneumonia Masks for the Prevention of Novel Coronavirus Infection” issued by the State Council’s Joint Prevention and Control Mechanism for Novel Coronavirus Infection Pneumonia (Epidemic Prevention and Control Group), the principles of handling masks after use are divided into two categories: There are two categories: masks used by healthy people should be disposed of in accordance with the requirements of domestic waste classification; masks worn by suspected cases or confirmed patients should not be discarded at will, but should be treated as medical waste and disposed of in strict accordance with the relevant procedures for medical waste.

Autoantigen Is it possible to skip the nucleic acid test? Of course not. Antigen detection is not a substitute for 48-hour nucleic acid detection. Antigen detection is an important supplement to viral nucleic acid detection, especially in the context of large-scale outbreaks of fast-spreading diseases like Omicron, and antigen detection is a very important supplement if the capacity of nucleic acid detection is insufficient. However, antigen testing is still limited to controlled groups, isolated groups, and close contact groups. It is not recommended for ordinary people to perform antigen testing. Antigen testing cannot be used as a diagnosis of exclusion or as a substitute for 48-hour nucleic acid testing. Because there are certain false positives and false negatives in the antigen test, if the antigen test is positive, the nucleic acid review must be carried out eventually.

The general public should proceed from the overall situation of epidemic prevention and control and be responsible for themselves and their families. Actively cooperate with nucleic acid testing. When queuing up for nucleic acid testing, keep in mind the five “must”s, that is, the arrival time must be on time, the information registration must be accurate, the waiting line must be orderly, the mask must be worn all the way, and the test must be left quickly.
