[Read the guidance]((http://www.dh.gov.uk/en/Publicationsandstatistics/Lettersandcirculars/Dearcolleagueletters/DH_132536).
On issuing the advice, Professor Dame Sally Davies, Chief Medical Officer and Chief Scientific Advisor, said:
“It is important the NHS takes all the necessary precautions to minimise the risk of contamination with Pseudomonas aeruginosa bacteria which can cause significant infections in very sick patients.
“The guidance we are issuing today reminds healthcare providers of the importance of high standards of infection control. It also provides them with helpful advice on best practice to prevent Pseudomonas aeruginosa in specialist care units, and gives clear and concise information on how to manage the risks.
“Health Departments across the UK have worked together to produce guidance, and we will continue to keep it under review.”
