The authors of a new paper that found increasingly concrete evidence that COVID-19 is “predominately” airborne say that we need to be focusing on preventing infections in indoor settings, and rethinking how ventilation systems either help spread or dissipate the virus.
According to University of Toronto Professor Dr. David Fisman, one of the authors of the study, the results of the report come as an important implication for experts and governments to consider more stringent measures public health control measures in indoor spaces.
Public health guidance on the spread of COVID-19 has, for the most part, been widely focused on direct contact with others and transmission via water droplets.
The evidence from Fisman and his colleagues’ review, however, points to aerosols as potentially being the main mode of transmission for the virus.
“That explains why we have these huge explosive outbreaks in places like church choirs and karaoke bars and spin studios, where people are vocalizing and creating a lot of aerosols.”
