Faster than PCR and more accurate than lateral flow tests (RAT), the latest tool against COVID-19 has four legs and a wet nose.
Recent studies investigating whether or not dogs could differentiate between COVID-positive samples and COVID-negative samples have shown that properly trained dogs could detect COVID-19 on clothing worn by infected people with up to 94.3% sensitivity: showing that they would correctly identify 94 out of every 100 infected people.* This compares with a sensitivity of 58-77% for RAT tests, and 97.2% for PCR tests. Dogs beat PCR tests on speed, making a diagnosis in under a second and were less invasive than a nasal swab. Furthermore, the study showed that the dogs were able to identify people who are asymptomatic and also those people with a low viral load.
