Segment 1: The article discusses a new study that suggests dogs might be able to detect COVID-19 in human saliva samples with a high level of accuracy.

Segment 2: The study involved training dogs to identify positive COVID-19 samples from a group of negative samples. The dogs were able to do this with a success rate of 96%.

Segment 3: Researchers believe that dogs have a heightened sense of smell that allows them to detect the unique odor associated with COVID-19.

Segment 4: If proven accurate, this method could be used as a quick and non-invasive tool for COVID-19 screening in airports, public places, and other areas where large gatherings occur.

Segment 5: However, further research is needed to validate these findings before implementing this method on a larger scale.
