Raw video: Researchers have released a 3D simulation showing how droplets of different sizes travel in an indoor airflow.
Researchers in Finland have released a chilling video that shows how coronavirus droplets can spread in indoor spaces.
Experts from Aalto University worked with the Finnish Meteorological Institute, VTT Technical Research Center of Finland and the University of Helsinki to investigate the airborne transmission and spread of coronavirus in indoor spaces.
Aalto University researchers say that, amid the easing of lockdown restrictions in many parts of the world, the video underlines the ongoing risks posed by COVID-19.
The 3D video simulation shows how droplets of different sizes travel in an indoor airflow over a four-minute period.
“Our simulations show that virtually all droplets of less than 50 micrometres – and thus the majority of those produced when coughing – dry up as particles before they reach the floor and then linger around as carried by the indoor airflows,” said Aalto University assistant professor and project coordinator Ville Vuorinen in the statement.
As part of the same project, the researchers released a video earlier this year that modeled the potential spread of coronavirus in a supermarket.
