Dogs as effective at detecting COVID-19 as PCR tests

Fast and reliable testing of COVID-19 can help in timely detection of the disease to control its spread and ensure that the patients can begin their treatment without any delay.

PCR tests can detect coronavirus, however, it comes with certain drawbacks, such as inadequate availability, restricted testing capacity, high costs and long turnaround time.

A new trial in Finland shows that dogs are as good at detecting COVID-19 as PCR tests.

These special dogs, which can be spotted at international airports, are trained to sniff for drugs and other nefarious items, helping to protect the population from illicitly smuggled items.

When it comes to detecting diseases, sniffer dogs are already used to warn of epileptic fits, cancer and Parkinson’s. Now these dogs are being trained to sniff out COVID-19.

New results, from the University of Helsinki, show labrador retrievers and white shepherds can spot up to 97 per cent of positive cases. Trained dogs are 99 percent accurate when confirming who is virus-free among airport passengers, the study claimed.

The Helsinki team trained four dogs — 3 labrador retrievers a white shepherd — to sniff out COVID in spring 2020. The dogs were exposed to skin samples — swabs taken from the neck, forehead and wrists — of 114 volunteers who tested positive for the virus. They were also exposed to samples from hundreds who were COVID-free.

During their training, the dogs were 92 per cent accurate at spotting those with the infection and 91 percent as confirming that someone was COVID-negative. The dogs signalled a positive case by either offering their paw or sitting. Their sniffing skills were almost as good even if a sample came from someone without symptoms (89 per cent).
