Abstract
COVID Sniffer Dogs: Technical and Ethical Concerns.
Highlights
Specialty section: This article was submitted to Animal Behavior and Welfare, a section of the journal Frontiers in Veterinary Science
Some diseases emit specific volatile organic compounds (VOCs) from exudates, which can be used as a diagnostic tool [1]
Several technical and ethical concerns may occur by using the dogs as sensors of subjects infected by SARS-CoV-2, which seem poorly considered by media and sometimes underestimated in scientific papers
Summary
Specialty section: This article was submitted to Animal Behavior and Welfare, a section of the journal Frontiers in Veterinary Science. It has been shown in recent studies that dogs can detect people infected with SARS-CoV-2 [16]. To warrant human and dog health, we analyzed the recent scientific literature and discussed different technical and ethical problems with the involvement of dogs for detecting SARS-CoV-2 in people: the “context-shift effect,” the overlap of VOC profiles in different diseases and odors that may occasionally co-occur, the procedure to collect samples, and the possible role of the animals as vectors in a zoonotic scenario.
