Is six feet enough for safe social distancing? Study says could be ‘insufficient’

WASHINGTON DC:  Researchers have found that the current social distancing guidelines of 6 feet may be insufficient because a mild cough occurring in low wind speeds of 4-15 kph can propel saliva droplets 18 feet.

Airborne transmission of viruses, like the virus causing COVID-19, is not well understood, but a good baseline for the study is a deeper understanding of how particles travel through the air when people cough.
