Not To Be Sniffed At?

It's not just drugs and explosives that sniffer dogs can detect! A pilot study (get it?) at Helsinki airport has used 4 dogs in a trial, to determine they can detect people infected with the Covid-19 virus (https://www.theguardian.com/world/2020/sep/24/close-to-100-accuracy-airport-enlists-sniffer-dogs-to-test-for-covid-19). It is reported that the dogs have close to 100% accuracy (unlike temperature measuring devices or immunological tests). The tests can be carried out within 1 minute (the dog bit only takes 10 seconds), so delays would be minimal. Sniffer dogs have been used successfully to screen other illnesses such as cancers, so this is a logical development. If the results are confirmed, it is possible that we will get sniffer dogs (or pigs, as they are also pretty good at olfactory detection) at the entrances to companies, universities, schools and football stadia.
