The public are being advised to keep distance of at least 6ft 6in from each other. A study by Massachusetts Institute of Technology says it is too small. The gap needs to be four times bigger, at around 26 feet .
The study found that viral droplets expelled in coughs and sneezes can travel in a moist, warm atmosphere at speeds of between 33 and 100ft per second.
This creates a cloud within the atmosphere that can span approximately 23ft to 27ft .
It has also been warned that droplets, which contribute to the rapid spread of covid-19, can remain suspended in the air for several hours.
