Proof-of-concept study shows dogs can detect COVID-19 in human sweat
Dec. 10 (UPI) -- "Working" dogs trained to perform search and rescue tasks, detect explosives or diseases such as colon cancer correctly identified people infected with COVID-19 up to 100% of the time, French researchers said Thursday. The findings suggest that dogs can confirm the presence of the virus by sniffing samples of human sweat, the researchers said in an article published by the journal PLOS ONE. Advertisement Although the results still need to be confirmed in larger studies, this proof-of-concept study indicates that trained dogs could provide a "non-invasive" alternative to currently available tests, researchers said. The dogs also could be used to detect people infected with COVID-19 in public places and hopefully prevent them from spreading the disease to others, the resear...
