Cough of a COVID-19 infected person can contaminate a larger volume of surrounding air than previously believed due to the jet-like flow created by the cough, according to recent research, published in the journal Physics of Fluids

In this study, the scientists studied the action of cough with the help of jet theory.

The findings showed that the first 5-8 seconds after coughing are responsible for suspending infectious droplets in the air and, thereby, spreading the disease.

It was found that after that time period, the cough cloud (the cloud of aerosols formed after a cough) starts dispersing.

When compared with a person wearing a surgical mask, the cough cloud was found to be 7 times larger in the person who did not wear a mask.

The volume of the cough cloud in a non-mask wearer was found to be 23 times larger than seen in the person wearing an N95 mask.

It was also stated that adopting some simple habits such as coughing into the elbow or using a handkerchief while coughing or sneezing, along with wearing masks, could help reduce the volume of the cough cloud.

With this study, scientists concluded that wearing a mask may not provide complete protection but can reduce the risk of transmitting the infection to other persons present in the room to a significant level.
