This document for Public Health England (PHE) health protection teams (HPT) provides:
- guidance when approached by infection, prevention and control teams and estate departments on maintaining their water systems to ensure there is a consistent and appropriate response from PHE
- information and practical guidance for HPT staff who are participating in incident control teams, or a water safety group
It describes situations where HPTs should be contacted, and the extent of involvement that can be expected of HPTs where legionella counts are detected in the hot and cold water systems (excludes cooling towers) of healthcare premises.
The guidance and accompanying algorithm (figure 1, p.10) applies to situations where there are no associated nosocomial cases, although it is possible that cases may subsequently be identified.
