In light of the scientific evidence and advice from international organizations that concur with a model of COVID-19 transmission through inhalation of viral particles, the IRSST recommends increasing respiratory protection for healthcare workers.

Exposure to SARS-CoV-2 is a known risk for healthcare workers. The recognition of inhalation as a mode of transmission as well as the emergence of new variants of the virus justify increased vigilance and require a reinforcement of protection measures.

The IRSST recommends adequate protection for healthcare workers who work with patients suspected or confirmed to have COVID-19 in care settings. This recommendation takes into account the scientific advice of many experts in Québec and internationally on the issue and is in addition to all existing prevention measures.
