  COVID-19: Smaller cough droplets may travel over 6 metres, says study

  November 04, 2020 12:55 IST

  The research, published in the journal Physics of Fluids, found that a single 100-micrometre cough droplet under wind speed of 2 metres per second can travel up to 6.6 metres and even further under dry air conditions due to droplet evaporation. "In addition to wearing a mask, we found social distancing to be generally effective, as droplet deposition is shown to be reduced on a person who is at least 1 meter from the cough," said study author Fong Yew Leong.
