German Study Finds Dogs Can Sniff Out COVID

Deutsche Welle reports:

Researchers in Germany have found that army sniffer dogs can discern between samples from coronavirus-infected and healthy patients. So high is the level of accuracy, they hope this can be used in real-life scenarios. Scientists at the University of Veterinary Medicine Hanover have found that trained sniffer dogs could be used to detect COVID-19 in human samples with a relatively high rate of accuracy, a study published on Thursday revealed.

Eight sniffer dogs from the German Bundeswehr were trained for only a week to distinguish between the mucus and saliva of patients infected with coronavirus and non-infected individuals. The dogs were then presented with positive and negative samples on a random basis by a machine. The animals were able to positively detect SARS-CoV-2 infected secretions with an 83% success rate, and control secretions at a rate of 96%. The overall detection rate, combining both, was 94%.
