dogs smelling covid https://www.nature.com/articles/d41586-020-03149-9 https://www.nature.com/articles/d41586-020-03149-9 : "Riad Sarkis, a surgeon and researcher at Saint Joseph University in Beirut, is part of a French–Lebanese project that has trained 18 dogs. Sarkis used the best two performers for the airport trial in Lebanon. The dogs screened 1,680 passengers and found 158 COVID-19 cases that were confirmed by PCR tests. The animals correctly identified negative results with 100% accuracy, and correctly detected 92% of positive cases, according to unpublished results." btw, 10% of passengers are covid positive, and i'd guess most are asymptomatic as most of them wouldn't be flying otherwise.
