There is a growing body of evidence supporting the airborne transmission of SARS-CoV-2, the virus that causes COVID-19. Despite updates from the World Health Organization, the U.S. Centers for Disease Control and Prevention (CDC) and the Public Health Agency of Canada indicating that the virus can be transmitted through short- and long-range aerosols. , Canada’s public health guidelines have not been properly updated. to address this mode of transmission, argue the authors of a comment posted on CMAJ (Journal of the Canadian Medical Association).

Canadian public health guidelines and practices need to be updated to include more emphasis on the following air mitigation measures: ventilation, filtration, and better masks.

“Ventilation is a key element in the fight against airborne transmission. We need clear guidelines and funding for evaluating and improving ventilation in our indoor spaces, particularly in our schools,” says Dr. Sarah Addleman, a physician. of Ottawa Hospital, Ottawa. Along with ventilation, it’s time to review the recommendations on Canadian personal protective equipment (PPE) in and other essential parameters.

“People who work for others (both in the healthcare field and in other environments) they run a higher risk of infection by inhaling short-range aerosols and better masks (such as N95) are needed to prevent infection, ”explains the co-author Victor Leung, Infectious Diseases Physician, University of British Columbia, Vancouver, British Columbia.

“It took the medical community decades to accept that tuberculosis and measles were airborne diseases. The science of airborne transmission of SARS-CoV-2 has advanced rapidly. It is time for Canadian guidelines and policies also follow quickly, “the authors conclude.
