Researchers have used the Fugaku supercomputer to model the emission and flow of virus-like particles from infected people in a variety of indoor environments.

Air humidity of lower than 30% resulted in more than double the amount of aerosolised particles compared to levels of 60% or higher,

as seen in simulations released on Tuesday (October 13) by research giant Riken and Kobe University.

Their findings suggest that the use of humidifiers may help limit infections during times when window ventilation is not possible.

The study also indicated that clear face shields are not as effective as tighter-fitting face masks in preventing the spread of aerosols.

Other findings showed the number of singers in choirs for example should be limited and spaced out.

There has been a growing consensus among health experts that the COVID-19 virus can be spread through the air.

The U.S. Centers for Disease Control and Prevention (CDC) revised its guidance this month to say the pathogen can linger in the air for hours.
