Conclusions• L. pneumophila were prevalent in both hospitalswith the Hospital A has a potential LD outbreak• High pH and free chlorine content wouldeliminate Legionella bacteria but may lead toscale and fouling formations• Isolation of L. pneumophila in the CT watersupply is equally alarming• The Hospital B had better engineering practicethan the Hospital A
Recommendations1. Good Engineering Practice2. Intervention Measure and Follow-up3. CT Survey at Other High Risk Public Places4. Legionella Isolation at Other Man-made Devices5. An Environmental Surveillance6. Molecular Identification of Legionella Strains
