Clearing the air on better ventilation to lower COVID risk

25 July 2021

Aerosol transmission is the main factor in spreading coronavirus and Australia needs to focus on delivering cleaner indoor air, argues Lidia Morawska.

Australia is now in the grip of its second winter marred by the pandemic, with crippling lockdowns in multiple cities.

Earlier this month, the federal government announced a four-stage plan to bring the country back to something resembling normality. Acknowledging it will be impossible to eradicate COVID-19 completely, the plan focuses on a variety of steps — most notably vaccination — to enable the country to live with the virus.

However, if we want this plan to work, there’s one crucial control measure yet to be considered: protection against airborne transmission of the infection in public indoor spaces.

We need to modernise our indoor environments to protect Australians from respiratory infections, and more broadly, from all indoor air hazards. This includes indoor exposure to pollution originating from outdoors, such as bushfire smoke.
