Dogs may be better at detecting Covid-19 than nasal PCR tests, study finds

Trained canines detected Covid in 97% of symptomatic cases and nearly 100% of asymptomatic cases

Trained dogs may be able to detect Covid-19 more effectively than nasal swab PCR tests, according to new research.

A study published on Wednesday by the peer-reviewed Plos One journal found that canines were able to better detect the presence of Covid than PCR antigenic tests in both symptomatic and asymptomatic people.
