No reliable test for Corona, I wonder if they could train dogs to recognize infected people before they show symptoms visually.
First think I thought of too.
Train dogs to find coronavirus.
My thoughts as well.
Dogs possess a sense of smell many times more sensitive than even the most advanced man-made instrument. Just how powerful is a pupper schnoz? Powerful enough to detect substances at concentrations of one part per trilliona single drop of liquid in 20 Olympic-size swimming pools. With training, dogs can sniff out bombs and drugs, pursue suspects, and find dead bodies. And more and more, theyre being used experimentally to detect human diseasecancer, diabetes, tuberculosis, and now, malariafrom smell alone. - https://www.wired.com/story/the-science-of-the-sniff-why-dogs-are-great-disease-detectors/
