Dogs, properly trained, discover easily and infallibly if a person is infected with SARS-CoV-2 the virus that causes the COVID 19 disease. Is it possible to build an artificial nose to detect those infected with the virus SARS-CoV-2 as dogs do?
Thanks for your friendly sharing. Mimicking natural processes is a well-known and succeeded way to scientific and technological development. Dogs are a happy example of amazing creatures. Surely that humans still have much to learn with such reliable and solidary creatures. I never forget one day, when I was kid, and I did fall down from a tree, that the first who came swiftly to trying to help me, was a dog.
Dear Ahmed Saeed Mohmed, I don't know if the virus has a smell but it is certain that in Dubai, Helsinki, and perhaps many other airports they use dogs to identify passengers infected with the virus SARS-CoV-2.
Dear Samuel Oluyomi Ayodele, I don't think it matters whether there is scientific basis or not. Dogs, properly trained, identify COVID 19 patients instantly and more reliably than swabs. This is an experimental fact regardless of the scientific basis and our clinical judgment.
Dear Leonardo Cannizzaro ,Of course in Germany and Britain I also read articles on the use of dogs In detecting a virus COVID 19 , but it requires many studies
A study investigated the possibility to train machine-learning classifiers with an electronic nose (Aeonose) to differentiate between COVID-19-positive and negative persons based on volatile organic compounds (VOCs) analysis.

Propely trained dogs can identify covid-19 patients more instantly than swabs as in Britain,Germany,Dubai Airports to identify infected passengers with this virus.
