Canada finally recognizes the danger of aerosols in the spread of COVID-19:

Covid-19: aerosols recognized as a propagation agent

The American Center for Disease control (CDC) has recognized the risk of airborn transmission of Covid-19. Following this announcement, the Public Health Agency of Canada (PHAC) adjusted and followed the same discourse as specialists in the international scientific community. To find out more, see the Radio-Canada article of November 5, 2020.

The federal government of Canada had not recognized the risk of airborne droplet spread prior to this update. Indeed, the old directives indicated that the virus was spread only by breathing droplets or by touching contaminated surfaces.

How is the Covid-19 virus transported in aerosols?


The anesthesiologist, Dr Alain Lamontagne, is one of those who have fully understood the risk of aerosol transmission. During an interview, he explains that the aerosols follow the air waves and do not settle within a radius of two meters. Instead, they remain suspended in the air for a long time. This spreading method is very problematic, especially in hospitals and in operating rooms.

The Solution

Following new directives from the federal government, the National Institute of Public Health of Quebec (INSPQ) quickly modified its recommendations to recognize the risk of airborn spreading.

To protect against droplets, the INSPQ recommends wearing the standard surgical mask and visor but these measures do not completely protect against the virus which are constantly suspended in the air. The MAXIMED is a filtration unit which captures at the source the aerosols which are rejected bythe patient. This means that the virus does not have time to spread.
