Bella, Erec and Lotta

 

Dogs are “superior smellers” and are already used to detect what the human nose typically cannot from diseases, such as Parkinson’s, cancer and diabetes, to drugs and explosives in public places, according to the American Lung Association.

Dogs’ noses have about 300 million scent receptors and are much more sensitive to smells compared to humans who have roughly 5 or 6 million scent receptors, according to the American Lung Association. In the authors’ most recent study, the nine dogs, with names such as Bella, Erec and Lotta, correctly identified 92.86% of long COVID samples as COVID-19 positive when long COVID samples were presented next to negative virus samples (scenario 2).
