Abstract
COVID-19 outbreak leads to morbidity and mortality. It is undeniable fact that both controlling infection and treatment are important for preventing the transmission of COVID-19. So, diagnosis of early stage of the disease and rapid identification of people who are infected with SARS-CoV-2 are vital. Various methods are currently used to diagnose of this disease, however there are limitations for current diagnostic methods such as cost, test results, time consuming, require specialized equipment and expertise. It is specified that a large number of human diseases have a specific smell. Probably each pathogen in individual can influence the released Volatile Organic Compounds (VOC) signals/profiles. Tracing changes in VOCs associated with certain disease can be used as unique fingerprints; also it can provide clues for early disease detection in order to prevent further outbreaks of infectious diseases. Dogs are be trained for smelling/ identifying any scented materials. Innumerable scientific articles indicate the importance of sniffer dogs in a spectrum range of applications. In this study, we scrutinize the properties of trained dogs for detection infected people with COVID-19.
