(Bloomberg) Dogs are able to detect Covid-19 in humans, a new study showed, paving the way for the broader use of sniffing canines in a global effort to contain the pandemic.
The dogs’ detection reached 97% sensitivity in the French study, meaning that’s how well the canines could identify positive samples. The sniffing was also 91% specific, which rates the dogs’ ability to identify negatives. The sensitivity rating beats that of many 15-minute antigen tests, which tend to be better at ruling out infection than at finding it.
The dogs’ detection reached 97% sensitivity meaning they were highly effective in detecting positive cases and 91% specificity meaning the number of false positives was very low.
