A positive rapid nucleic acid test in an environmental sample from a vaccination unit often indicates the presence of the New Coronavirus in the area where the sample was collected.
Recently, it is common to see "Positive rapid nucleic acid test in environmental specimens from a vaccination unit." These kinds of news reports are often seen.
Does a positive environmental Nucleic Acid Rapid Test sample from a vaccination site mean that the vaccination site is contaminated with the virus? The answer is not necessarily!
As the name implies, inactivation means that the virus is inactivated and has no ability to cause disease, but the "body" and nucleic acid fragments of the virus are retained. The preserved nucleic acid fragments will still respond to the new crown nucleic acid rapid test.
In the vaccination environment, the vaccine often leaks due to the pumping and other operations of the health care provider, thus creating an aerosol transmission of the new crown vaccine and leaving the inactivated virus in the environment.
So, if the virus in the inactivated vaccine is dead, why is the rapid test for New Crown nucleic acid still positive for environmental samples?
This has to do with the principle of the Nucleic Acid Rapid Test.
The novel coronavirus is an RNA-only virus, and its specific RNA sequence is the marker that distinguishes the virus from other pathogens. This specific sequence is detected by a real-time fluorescence PCR method that directly detects the specific RNA sequence of the novel coronavirus at the genetic level, and if a specific nucleic acid sequence matching the standard sample is detected in the sample, a positive result of the rapid nucleic acid test for the new coronavirus is indicated. This can be understood as two magnets attracting each other, which will produce a positive result.
Once the principle is understood, it is the process of the New Crown Nucleic Acid Rapid Test.
Although we only collect a small amount of sample nucleic acid in the environment, but through the process of purification of nucleic acid, extraction of nucleic acid, amplification of nucleic acid and other processes, the number of nucleic acid will be more than the number of collected, and finally through sensitive analysis of the comparison will come out the results of nucleic acid detection.
The full process of conventional pcr nucleic acid testing takes about 2-3 hours, and now the new crown nucleic acid rapid testing program proposed by various testing companies to continuously improve their technology can already complete the whole process of nucleic acid testing within 1 hour!
This positive rapid nucleic acid test for neo-crown in the vaccination environment due to the formation of aerosol transmission from vaccine volatilization is not a viral infection in humans, but will react to the nucleic acid test for neo-crown virus.
In this regard, the CDC said that it is not recommended to routinely conduct environmental specimen collection and rapid nucleic acid testing for new crown nucleic acid in vaccination units. If a rapid new crown nucleic acid akin side is carried out and found positive, a more comprehensive sequencing method should be used to further verify that this inoculated environmental sample is indeed a live virus with infectivity.

If you see that the environmental sampling of the vaccination site where you received the vaccine is positive for New Coronavirus rapid akin testing, there is no need to panic too much. You can contact your local government personnel and ask for further results of the environmental testing and perform New Coronavirus rapid akin testing to confirm whether you are infected with New Coronavirus.
