Dogs have been helping to keep humans safe by sniffing out narcotics, explosive devices, pests, natural disasters, cancer, and now the Coronavirus.
A medical charity in England is attempting to train dogs to identify the smell of COVID-19.
The aim is that dogs will be able to screen anyone, including those who are asymptomatic and tell us whether they need to be tested.
Other respiratory diseases like COVID-19, change our body odor so there is a very high chance that dogs will be able to detect it.
If the research is successful, we could use COVID-19 detection dogs at airports at the end of the epidemic to rapidly identify people carrying the virus. This would help prevent the re-emergence of the disease.
