The technology for detecting exists. the only question would be whether the machines could pinpoint the particular virus. Since they have individual tests that detect the Corona virus, there is no reason that couldn't be done. These things operate on a molecular level. Quick answers often reflect a lack of thought.
An explosives trace-detection portal machine, also known as a trace portal machine and commonly known as a puffer machine, is a security device that seeks to detect explosives and illegal drugs at airports and other sensitive facilities as a part of airport security screening.[1] The machines are intended as a secondary screening device, used as a complement to, rather than a substitute for, traditional X-ray machines.
The term "trace-detection" refers to the machine's ability to detect extremely small "traces" of these compounds. The exact sensitivities of these machines is not available information, but a mass spectrometer detects compounds on a molecular level and would only be limited by the efficiency of the collection from the air puffed to obtain a sample for analysis.
