A new study in JAMA Internal Medicine, with the participation of Drs. Todd Lee, Emily McDonald and Nandini Dendukuri  of the IDIGH Program,  confirms the efficiency of saliva testing for COVID-19. This publication could influence global public health policies, who are hesitant to implement saliva tests, in the testing strategies to fight against COVID-19.

Previous studies on the performance of saliva tests showed mixed results, but most of them compared saliva tests to the standard nasal swab test, as if it was a perfect test. Interestingly, there are no perfect tests for COVID-19—Dr Guillaume Butler-Laporte, first author of the study.
