Could dogs be trained to sniff out Covid-19 cases?

Man's best friend has been used to sniff out drugs at airports and even to detect cancers. Now the London school of Hygiene and Tropical Disease in the United Kingdom has started a programme to train dogs to sniff out cases of Covid-19 on carriers that may not have other symptoms like fever. This would be particularly useful at the end of the lockdown when ports re-open. Prof James Logan, the head of the School’s Department of Disease Control said the success they have had with dogs in sniffing out diseases such as malaria prompted the decision. He also sheds light on whether we can pass on the novel coronavirus to our pets. - Linda van Tilburg
