Respiratory Droplets May Go Further than 6 Feet

- Health officials advise people to stay 6 feets apart to curb the spread of the coronavirus. This is said to be how far respiratory droplets, which transmit the virus, can go. However, scientists have found new evidence showing that droplets can reach beyond 6 feets, suggesting that this recommendation may be ineffective
- The team of researchers from the University of Cyprus found that even at a wind speed of 2 miles per hour - the speed needed for smoke to move through air = saliva and respiratory droplets can travel up to 18 feets in 15 seconds
- The team assessed how far saliva can travel in air using a computer simulation that also factored in conditions such as humidity and size of droplets, which influence speed of droplets in air
- More than 3,0000 droplets are expelled from an unguarded cough while a sneeze releases up to 40,000 droplets, all dispersed in different directions
- The findings of the study come as some world leaders call for closing in on the social distance to enable economic activities around the world
