Dogs can sniff out COVID-19

 

In a pilot study at the University of Helsinki, dogs trained as medical diagnostic assistants were taught to recognize the previously unknown odor signature of the COVID-19 disease caused by the novel coronavirus.

And they learned with astonishing success: After only a few weeks, the first dogs were able to accurately distinguish urine samples from COVID-19 patients from urine samples of healthy individuals.

" After only a short time, the animals identified the urine of people infected by the novel coronavirus, known as  SARS-CoV-2, almost as reliably as a standard PCR test," says DogRisk group leader Anna Hielm-Björkman.

The Finnish scientists are now preparing a randomized, double-blind study in which the dogs will sniff a larger number of patient samples. Only then will the scent tests be used in clinical practice.

Important findings for other teams

The very rapid and promising findings from Finland are also important for other research teams, such as those in Great Britain and France, who are training sniffer dogs to detect COVID-19.
