Loss of smell is a prominent complain in covid-19
Dogs can recognise a distinctive odour produced by people with the virus but undetectable to the human race.
In a study, it was found that trained dogs could pick up 88% cases of Covid-19. They could distinguish Covid from other respiratory virus. In 30 minutes, dogs could screen 30,000 travellers in an airport and they are more accurate than our lateral flow test. ( slide test for Covid-19.)

Taking these facts and figures in to account, a Singapore based start-up company has now developed a Covid-19 breathalyser test in collaboration with the National University of Singapore.
The breath test achieved more than 90% accuracy in a pilot study and has been approved by Singapore for clinical use.
One lakh years ago, our sense of smell is one of the primary defence mechanism in the survival of our forefathers in the pre-historic jungles of Africa. Evolutionarily, our sense of smell resides in the most primitive part of our brain near the hippocampus.
Today, as a virus tries to annihilate the mankind from the face of earth, first thing it tries is to cut off is our sense of smell. Now that very sense of smell will help us fight the menace.
