A team led by Professor James Logan, Head of the Department of Disease Control at the London School of Hygiene & Tropical Medicine, is training a team of dogs to detect odors from humans with COVID-19 infections. 

The dogs would provide non-invasive and rapid diagnosis in ports of entry, like airports. The welfare of the dogs is paramount – the coronavirus samples used during the training are sterile and there is little evidence that dogs are particularly susceptible to the novel coronavirus.
