The authors of the study published in the journal Physics of fluids are physicist Talib Dbouk and engineer Dimitris Drikakis from the University of Nicosia, Republic of cyberspace. The study is conducted from observing the correlation between regions with increased COVID-19 incidence and the US national allergy map.
Researchers have created a computer simulation of how a lily tree pollinates in air. In the gentle wind, the model shows pollen can fly to a crowd more than 20m away in just 1 minute, capable of spreading the virus on the runway.
They said that on a sunny day, on average a tree can put more than 40 pollen grains per 0.3m3 into the air and each pollen grain can carry hundreds of viruses.
Based on that result, the researchers said that a distance of 2m is often recommended to reduce the risk of the spread of the COVID-19 virus, which may not always be enough. They hope to call for attention to the surprising ways viruses like SARS-CoV-2 can spread.
The two scientists are seeking to better understand the interaction between pollen particles in the air and the human respiratory system under different environmental conditions.
