Japan Supercomputer Shows Humidity Affects Aerosol Spread of Coronavirus

Humidity can have a major impact on the dispersion of virus particles, according to a study by researchers at Kobe University in Japan and research giant Riken.

The researchers modeled the emission and flow of virus-like particles from infected people in a variety of indoor environments using the Fugaku supercomputer.

The simulations showed more than double the amount of aerosolized particles in the air when humidity was lower than 30%, compared to when the humidity was 60% or higher.

This suggests coronavirus contagion risks could increase in dry, indoor conditions during the winter months.

The researchers also found clear face shields less effective than masks in curtailing the spread of aerosols.
