Published in a journal by the American Institute of Physics on Tuesday, the study aims to estimate the amount of air contaminated by cough in Covid-19 patients.
The survey was conducted by Professor Amit Agrawar and Professor Rajny Schwaradwaji, who belong to the Department of Mechanical Engineering of IIT Bombay.

“The presence of the mask greatly reduces the volume and the risk of viral infections of others in the room. Similarly, actions such as coughing on the elbows and using handkerchiefs can cause coughing clouds. You can reduce the amount of the virus, and as a result, reduce the chances of the virus spreading, “the study said.
Researchers have attempted to analyze the volume, temperature, and relative humidity of clouds created by coughing to understand their dispersion in the surrounding air.
They used mathematical models to analyze the hydrodynamics and thermodynamics of cough clouds. They found that the cough cloud lasted 5-14 seconds and then disappeared.
“The N-95 mask not only reduces the number of droplets that a Covid-19 patient exhales, but also reduces the amount of infected air that he or she produces,” the researchers say.
They were confident that the findings would help us understand how SARS-CoV2, which causes Covid-19, spreads in the air.
