They added that any mask is better than no mask at preventing coronavirus
The study said that airborne transmission by respiratory aerosol droplets produced during coughing and sneezing is the dominant mode of spreading of coronavirus kind of disease
The study published in the journal Physics of Fluids, found N-95 masks to be the most effective at reducing the horizontal spread of a cough.
It is reported that the N-95 masks reduced a cough's initial velocity by up to a factor of 10, and limit its spread to between 0.1 and 0.25 meters
The study added that an uncovered cough, in contrast, can travel up to three metres, but even a simple disposable mask can bring this all the way down to 0.5 metres
Tip: N-95 masks with valved respirators do not prevent the virus from spreading out and are “detrimental” to the measures adopted for its containment. Look out for N-95 mask without valve.
