People concerned about hospital cleanliness in the U.K. are being urged to challenge health workers on whether they have washed their hands.

Andrew Pike, chief executive of South East Essex Primary Care Trust, said,

"We would encourage people using health services to question any healthcare worker, whether in hospital or the community, if they have washed their hands."
