The UK's coronavirus social distancing limit is at least four times too short, a study has warned.
The public are currently being asked to keep a distance from each other of at least 6ft 6in (2 metres). But a new study by the Massachusetts Institute of Technology (MIT) suggests the gap should be four times bigger at around 26 feet (8 metres).
The study, which was reported by the Telegraph, 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 (10 metres to 30 metres).
This creates a cloud within the atmosphere that can span approximately 23ft to 27ft (7 metres to 8 metres) to neighbouring people. 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.
And their direction can easily be changed by air ventilation systems to create 'turbulent clouds of air.'
Many people are now finding themselves in close quarters with others on a daily basis, with supermarkets still feeling the effects of mass panic buying of products.
In London, despite persistent calls from the Government for only essential workers to continue with the morning commute, images have revealed packed carriages on the London Underground. The authors of the MIT study offered further clarity on their findings, and detailed why social distancing needs to be increased within the Journal of the American Medical Association (JAMA).
'These distances are based on estimates of range that have not considered the possible presence of a high-momentum cloud carrying the droplets long distances,' they said. 'Given the turbulent puff cloud dynamic model, recommendations for separations of three feet to six feet (1 metre to 2 metres) may underestimate the distance, timescale, and persistence over which the cloud and its pathogenic payload travel, thus generating an underappreciated potential exposure range for a healthcare worker...
