Trained dogs can sniff out Covid with up to 94% accuracy - including new variants
Specially trained dogs are able to sniff out Covid-19 with up to 94 per cent accuracy, new research suggests.
A coronavirus infection has a distinct smell meaning canines are able to detect samples from people who have been infected but are asymptomatic, as well as those with low viral loads.

Findings “give hope”
The findings of the UK study, which has not yet been peer-reviewed, are based on six dogs who tested more than 3,500 odour samples donated by the public and NHS staff.
The dogs, Asher, Kyp, Lexia, Tala, Millie and Marlow, from the charity Medical Detection Dogs, took part in the double-blind trial.
This means that neither the research team nor the dogs knew which of the odour samples came from people infected with coronavirus, and which were Covid-free.
