Covid-19 detection by dogs

The extremely sensitive olfactory sense of dogs, as a tool for detecting infections, is currently being tested in field at the Helsinki-Vantaa airport. The "corona dogs" are in duty at the airport providing airpassangers a change to get tested for corona infection.
Project background

In spring 2020, a joint agreement of cooperation on a research project was signed by the University of Helsinki, HUS, University of Eastern Finland, University of Oulu and NGO Wise Nose - The Smell Detection Association in Finland.

Research aimed first to investigate if trained dogs were able to identify and clearly point out positive samples of Covid-19 from urine and sweat (wiped from skin) samples. The aim of the study was to enable immediate and cost effective early diagnosis of the disease at a strategic site, the Helsinki-Vantaa International airport in Finland.

In addition, two yet to be published studies document how small concentrations trained dogs indicate successfully and how the dogs can be trained to work in smell detection, in order to create cost effective training programs for dogs in the future. 

The project was launched in autumn 2020 by docent Anna Hielm-Björkman and her Dogrisk-research group in cooperation with professor Anu Kantele from HUS, professor Olli Vapalahti from the University of Helsinki, the city of Vantaa, and Wise Nose ry.

The Covid-19 detection dog validation article is now accepted and will soon be published (14.3.2022).

Scent dogs in detection of COVID-19: triple-blinded randomised trial and operational real-life screening in airport setting

This large randomised controlled triple-blinded validation study with a precalculated sample size conducted at an international airport showed that trained scent dogs screen airport passenger samples with high accuracy. One of our findings highlights the importance of continuous retraining as new variants emerge. Using scent dogs may present a valuable approach for high-throughput, rapid screening of large numbers of people.
