Researchers from the University of Nicosia in Cyprus said that pollen from trees might spread viruses such as COVID-19, Report informs.

Scientists have created a computer model of willow and simulated the distribution of its pollen. To do this, they used advanced hydrodynamic models.

It turned out that with a light wind, pollen can fly 20 meters in a minute, carrying virus particles through a crowd of people.

The authors of the study concluded that a distance of 1.5 meters is not enough to reduce the risk of the spread of coronavirus.
