The risk of the spread of coronavirus infection increases when people follow rapidly in narrow places. This has been revealed in a study done in China. According to the study, when the infected person walks in such places, there is an increased risk of infection from the virus present in the inhaled droplets left behind.
The study, published in a research journal Physics of Fluids, gave the results of computer simulations describing how the shape of a place can help spread airborne infections. Earlier research in glass, windows, and air conditioning (AC) study the effect on airflow.
However, now scientists at the Chinese Academy of Sciences in Beijing say that the simulations conducted by them were researched in large and open spaces. According to the study, if a person walking in a narrow place cough, then the droplets coming out of his breath form the same lines behind his body as the boat formed in water.
According to the study, the droplets coming out of the mouth become densely cloudy in the air and go far beyond the person’s body. Researcher Xiaoli Yang said that this puts people at risk of infection, walking back and forth on narrow passages.
