New coronavirus may spread as an airborne aerosol, like SARS
"The novel coronavirus SARS-CoV-2 can survive in the air for several hours in fine particles known as aerosols, according to preliminary research.
The coronavirus, which causes the respiratory infection COVID-19, can be detected up to 3 hours after aerosolization and can infect cells throughout that time period, the study authors found. However, the study, first posted March 10 on the preprint database medRxiv, is still preliminary, because it has not undergone extensive peer-review. The authors did receive comments from one prospective scientific journal, and posted an updated version of the study on March 13 reflecting the revisions."
"More important, even if aerosol transmission can occur, it's unlikely to be the primary force driving the current pandemic, Morris added."
"The current scientific consensus is that most transmission via respiratory secretions happens in the form of large respiratory droplets ... rather than small aerosols," he said. "Droplets, fortunately, are heavy enough that they don't travel very far" and instead fall from the air after traveling only a few feet. "
