Muslim doctors and nurses are to be allowed to opt out of strict hygiene rules introduced by the NHS to restrict the spread of hospital superbugs. Female staff who follow the Islamic faith will be allowed to cover their arms to preserve their modesty despite earlier guidance that all staff should be "bare below the elbow". The Department of Health has also relaxed rules prohibiting jewellery ... The rules were drawn up to reduce the number of patients who were falling ill, and even dying, from superbugs such as MRSA and Clostridium difficile.
