A study performed at the University of Veterinary Medicine Hanover in Germany found that trained sniffer dogs may be used to detect COVID-19 in human samples with a relatively high rate of accuracy, reports DW.
German military sniffer dogs — who can already detect explosives, drugs, various cancers and hypoglycemia in diabetics — were trained for a week to distinguish between the mucus and saliva of COVID-19 infected patients and samples from non-infected people, noted DW.
The dogs were able to pick the infected mucus and saliva at an 83% success rate. The pooches chose the non-infected samples at at a rate of 96%. By combining both results, the dogs’ overall detection rate was 94%.
