The depth of the fears about Ebola spreading to the US have been encapsulated in a picture of a woman wearing a home-made Hazmat suit at an airport.

The picture went viral online after it was posted on the US news and opinion website The Dally Caller.

The passenger is wearing a full body gown, mask and gloves and is reading a piece of paper.

The picture was reportedly taken by another traveller at Dulles International Airport outside Washington DC earlier this week.
