The group determined these dogs can spot COVID with a 90% to 100% accuracy rate, but there is more work to be done.

“Delta variant has changed things,” said Maurice Maurer, Assistance Dogs of Hawaii’s executive director. “We’re needing to get more samples of people that have the delta variant. We’re hopeful that more people will be training COVID detection dogs and utilizing them at places like hospitals, airports, schools and really anywhere there are large, public gatherings.”
