Moisture in the air has a significant effect on the spread of virus particles, which can increase the risk of coronavirus infection in the winter months during dry indoor conditions, a Japanese supercomputer has found.
According to a recent study from the Riken Research Institute and Kobe University, the results suggest that
Humidifiers can help reduce the risk of infection during periods when ventilation is not possible.
Japanese experts used the Fugaku supercomputer to model the release and flow of virus-like particles from infected people indoors with different properties.
Air with a humidity of less than 30 percent has more than twice as many aerosol particles as air with a humidity of at least 60 percent
simulation showed.
Research has also shown that a face shield does not provide as effective protection against the spread of aerosols as mouth and nose masks. The results also showed that people who sit next to a person are more at risk from eating than those who sit next to them.
A research team led by Cubokura Makoto has previously studied the risk of infection in trains, workplaces and classrooms using Fugaku.
