Daily Mail: Millions of us spend our days slaving over a keyboard. But lurking between the keys, hidden on the mouse and nestled in your phone lies more than 10 million bacteria - 400 times more than on the average toilet seat.

Unhygienic working conditions are a 'key contributor' to the 131 million working days lost each year in the UK and millions more around the world, to illnesses including colds and flu.

Hygiene expert and visiting professor at the University of Salford, Dr Lisa Ackerley said bacteria and viruses can multiply on hard surfaces, remaining infectious for up to 24 hours.
