Dogs could screen up to 250 people an hour for coronavirus

A £500k grant is going to help move forward a way to detect coronavirus using dogs from a Buckinghamshire charity.

The government money will help Medical Detection Dogs with their research into quick screening of around 250 people an hour using the animals.

They can now trial using the dogs to sniff out the disease.

  • 'Covid dogs' to be trialled as potential non-invasive detection approach for the virus in the future
  • The dogs, who successfully detect certain cancers, will undergo intensive training to see if they can spot coronavirus before symptoms appear
  • Clinical trial backed by half a million pounds of government funding for innovative schemes 

What's happening?

Medical detection dogs

World-leading researchers at the London School of Hygiene & Tropical Medicine (LSHTM) will carry out the first phase of a trial in collaboration with the charity Medical Detection Dogs and Durham University, backed by £500,000 of government funding.

This aims to determine whether dogs are able to detect coronavirus in humans from odour samples.  

The trial brings together leading disease control experts from the universities with Medical Detection Dogs, who have already successfully trained dogs to detect the odour of many different diseases in humans, such as cancer, malaria and Parkinson's disease.

This new trial will look at whether the dogs, a mixture of Labradors and Cocker Spaniels, can be trained to detect coronavirus in people too, even if they aren't showing symptoms.

Minister for Innovation Lord Bethell said:

"Bio-detection dogs already detect specific cancers and we believe this innovation might provide speedy results as part of our wider testing strategy.

"Accuracy is essential so this trial will tell us whether 'covid dogs' can reliably detect the virus and stop it spreading."

If successful, these dogs could provide a fast and non-invasive detection method alongside the Government's robust five-pillar testing strategy. It is one of a number of testing measures being explored in order to ensure the government's response to the virus is as extensive as possible.

The initial phase of the trial will see NHS staff in London hospitals collect odour samples from people who are infected with coronavirus and those who are uninfected. The six bio detection dogs will then undergo thorough training to identify the virus from the samples.

More than ten years of research gathered by Medical Detection Dogs has shown that the dogs, which could each screen up to 250 people per hour, can be trained to detect the odour of disease at the equivalent dilution of one teaspoon of sugar in two Olympic-sized swimming pools of water.

This could be revolutionary

Professor James Logan, lead researcher for the work and Head of the Department of Disease Control at the London School of Hygiene & Tropical Medicine, said:

"Our previous work has shown that malaria has a distinctive odour, and with Medical Detection Dogs, we successfully trained dogs to accurately detect malaria. This, combined with the knowledge that respiratory disease can change body odour, makes us hopeful that the dogs can also detect COVID-19.

"I would like to thank the UK government for their support of this pioneering research through this funding. We're excited to do this trial, and confirm whether these bio detection dogs can be used to screen for COVID-19.

"If successful, this approach could revolutionise how we detect the virus, with the potential to screen high numbers of people."

The so-called Super Six

Medical Detection Dogs and the universities put forward a proposal for the clinical trial to the government, which has been accepted following strong evidence that the dogs can detect other diseases in humans with a high level of accuracy.

The dogs will only be deployed if backed by strong scientific evidence and is part of the government's approach to explore all possible options to tackle coronavirus.

Dr Claire Guest, Co-Founder and CEO of Medical Detection Dogs said:

"We are delighted that the government has given us the opportunity to demonstrate that dogs can play a role in the fight against COVID-19. They have the potential to help by quickly screening people, which could be vital in the future.

"We have already demonstrated our expertise in canine disease detection by successfully training dogs to detect diseases like cancer, Parkinson's and malaria, and we apply that same science to train life-saving Medical Alert Assistance Dogs to detect odour changes in individuals caused by their health condition.

"We are sure our dogs will be able to find the odour of COVID-19 and we will then move into a second phase to test them in live situations, following which we hope to work with other agencies to train more dogs for deployment. We are incredibly proud that a dog's nose could once again save many lives."
