A team of Canadian researchers has conducted a new study that argues that droplets released via unobstructed cough can travel across a distance of two meters (or six feet) it approximately 3 seconds while also being able to travel even further.

The study took place between the 2017-2018 flu season when coronavirus was still far in the distance. Even if a person is located at a distance of 2.5 meters away from the person who is coughing, the droplets can travel over a distance of 20 centimeters (or eight-inch) per second. It is even more daunting that the droplets can remain suspended in the air for more than 4 seconds.

WHO (the World Health Organization) has stated in the past that the virus spreads via saliva droplets and contacts with contaminated researchers. A study published earlier this month by an MIT researcher has also claimed that contaminated droplets could travel across 27 feet, powered by powerful sneezes or coughs that release a large turbulent gas cloud.

The MIT researchers suggested that the social distancing limit should be increased beyond the current six feet (2 meters range) to reduce the risk of exposure, especially since it not known if the N95 masks are effective in these circumstances.

New research infers that exhalations, sneezes, and coughs will contribute to the release of mucosalivary droplets, which can pursue a  semi ballistic emission trajectory. A multiphase turbulent gas cloud will also be released, and it can retain and carry clusters of droplets with various sizes. It is estimated that the lifetime of the droplet can be boosted from a fraction of a second to several meetings. However, a renowned expert has already criticized the MIT study, noting that some of the claims are only available in the case of people with very long sneezes.

The Canadian study will be published soon in a scientific journal.
