Japan supercomputer shows humidity affects the aerosol spread of coronavirus.

TOKYO (Reuters) — A Japanese supercomputer showed that humidity can significantly affect virus particles’ dispersion, pointing to heightened coronavirus contagion risks in dry, indoor conditions during the winter months.

The finding suggests that the use of humidifiers may help limit infections during times when window ventilation is not possible, according to a study released on Tuesday by research giant Riken and Kobe University.
