Crowded NHS hospitals with too few nurses could reverse the progress made by infection control teams in the past 20 years, according to an article on the Nursing Times website.
Antibiotic Research UK said the bed occupancy at NHS hospitals make the spread of bacterial infections more likely.
The group warned staff shortages meant time-pressed nurses may be too busy to spot inadequate levels of cleanliness.
“I have even heard of cases where administrative staff were being asked to help clean wards,” said Antibiotic Research UK ’s chief executive, Professor Colin Garner.
