Beijing: High-speed walking in tight spaces behind groups of people can increase significantly COVID-19 (new coronavirus infection) (# If there is no character limit, add parentheses when it first appears Risk of infection, especially in children, according to studies showing that respiratory droplets containing the virus can follow Infected individual Move through such a corridor.

The results of computer simulations published in the journal Physics of Fluids emphasized the importance of spatial shape in predicting how virus-laden droplets move in the air.

Previous studies have emphasized the effects of objects such as glass barriers, windows, and air conditioners on airflow patterns and virus spread, but scientists at the Chinese Academy of Sciences in Beijing have found that these simulations are usually large. He said he envisioned an open indoor space.

However, the researchers added that the effects of nearby walls that might exist in narrow corridors were not taken into account.

Current research shows that when a person walking in a corridor coughs, his breath ejects droplets that move around and behind his body, much like a wake is formed underwater as a boat moves. Form a wake.

Research has shown that there is a “recirculating bubble” just behind a person’s torso, with a long wake running almost waist-high behind it.

“The flow patterns we find are strongly related to the shape of the human body,” said study co-author Xiaolei Yang.

“2 meters downstream, the wake is almost negligible. Mouth height It’s leg-high, but it’s also visible at waist-high, “Yang said.

Once the airflow pattern was determined, scientists modeled the dispersion of a cloud of droplets emitted from the simulated human mouth.

They said that the shape of the space surrounding the moving person is especially important for this part of the calculation.

In one mode of dispersion, research has found that a cloud of droplets floats far behind a moving person, creating floating bubbles of droplets containing the virus.

In another mode, clouds are said to be attached to a person’s back and attached to the back like a tail as they move through space.

“In the separation mode, after 5 seconds of coughing, the droplet concentration is much higher than in the adhesion mode,” says Yang.

“This is a major challenge in determining safe social distances, such as in very narrow corridors, where patients can inhale viral droplets even in front of them,” he said. I added.

Scientists warn that droplet clouds are particularly dangerous to children, as they appear to float at a distance above the ground, about half the height of the infected person, which is the height of the children’s mouth. Did.
