A Polymerase Chain Reaction (PCR) test of a nasal swab is still the 'gold standard' for detecting a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, PCR testing could be usefully complemented by non-invasive, fast, reliable, cheap methods for detecting infected individuals in busy areas (e.g.

One hundred volunteers with COVID-like symptoms were invited to participate, and both axillary sweat samples for dog detection and nasopharynx/oropharynx swabs for qPCR were collected. Two dogs, previously trained, detected 97.

The aim of this study is to test if the sniffer dogs can be successfully trained to identify subjects with COVID-19 for 'proof of concept' and 'non-inferiority' against PCR. We are calling this method, Dognosis (DN).

- The study aimed to determine if trained dogs can differentiate between sweat samples from symptomatic COVID-19 positive individuals and asymptomatic COVID-19 negative individuals.
- Conducted in Paris and Beirut, the experiment involved six detection dogs trained over one to three weeks, using sweat samples from 177 participants (95 symptomatic and 82 asymptomatic).
- Results showed success rates between 76% to 100% for the dogs, indicating potential ability to identify COVID-19 positive samples, but findings need further validation due to study limitations.
