An investigation by researchers at the Indian Institute of Technology Bombay has shown that even light winds of around 5 mph can increase the spread of cough, reducing effective social distancing from 3 to 6 feet to 3.6 to 7.2, depending on the strength of the cough. Can extend up to ft.

Amit Aggarwal, co-author of the report, said: “The study is significant in that it points to an increased infection risk that coughing can occur in the same direction that wind can bring it.


“Based on the results, we recommend wearing a mask outside, especially in windy conditions.”

As the delta variant continues to spread across the US, the Centers for Disease Control and Prevention recommends that even vaccinated households wear a mask to prevent exposure and transmission of the virus.

Other guidelines, such as coughing into the elbow or turning your face while coughing, should still be followed to reduce transmission while outdoors.

However, guidelines are less clear on what people should do when they are outside.
