A little breeze? The coronavirus can travel longer in the air, according to a recent study. The mask outdoors can then be a solution to protect against infection.
Wearing a mask is the best way to protect yourselfin enclosed and frequented places. Under certain conditions it could also be useful outdoors. Researchers fromIndian Institute of Technology, in Bombay, modeled the journey of microdroplets expelled during a in windy conditions.
Coronavirus carried by the wind
Unsurprisingly, when thes go in the same direction as the , they stay longer in suspension in the and therefore travel further. Scientists have made a which recreates a sneeze and the airflow it causes in windy, calm conditions. If the wind is at 8 km / h, and the sneezing goes in the same direction, the by 20%, even outdoors.
When the wind is even stronger, around 15 km / h,to minimize the risk of contamination. ” Increasing the residence time of the larger droplets will increase the viral load transmitted by the cough stream and, therefore, the risk of infection. Overall, the study highlights an increased risk of infection even in the presence of a light breeze. », Explains Amit Agrawal, co-author of this study published in .
In certain weather conditions and during outdoor gatherings, wearing a mask appears to be an effective barrier against the coronavirus.
