Dogs have been our companions since ages. Could they also be our next allies in the fight against Covid-19? They can, say researchers as a new study indicates that trained medical scent dogs can effectively be used for screening people infected with the Covid-19 virus more rapidly and accurately.

"The most striking result is that studies have already demonstrated that dogs can identify people who are Covid-19 positive. Not only that, they can do it non-intrusively, more rapidly and with comparable or possibly better accuracy than our conventional detection tests," said researcher Tommy Dickey from the University of California, Santa Barbara in the US.
