nucleic acid testing
Nucleic acid detection is the most effective means to detect whether novel coronavirus is carried in human body. Whether the health code will change color without nucleic acid detection needs specific analysis. If the community or street requires all staff to do nucleic acid testing, in this case, the health code may cause the health code to change color, and generally a yellow code will be given.
If the health code becomes yellow and you want to go back to the green code, you must do nucleic acid testing. Many people think that the yellow code will be released automatically, so avoid nucleic acid testing. This is actually a wrong idea. If it becomes a yellow code, you must report it in time and do nucleic acid testing. If it is negative, the health code will turn into a green code within 24 hours.
The purpose of nucleic acid testing is to check whether there are positive COVID-19-infected people. In addition, after being infected by the mutated COVID-19 virus strain, the symptoms are mild and the transmission ability is strong. It is difficult to find infected COVID-19 by itself, so it needs to be detected by COVID-19 nucleic acid. Therefore, in order to prevent the spread of the epidemic and find the hidden infected people as early as possible, it is necessary for all nucleic acids to be used in risky areas, and everyone must complete it according to the regulations.
