A case of breathlessness, confusion and diarrhoea.
A 61-year-old woman presented to the emergency department with acute-onset breathlessness, fever, sore throat and confusion. Her initial investigations revealed hyponatremia and middle lobe consolidation. In view of the atypical symptoms and signs, erythromycin was commenced. Urinary legionella antigen was requested and that tested positive. She was one of the first few patients whose findings alerted us to a possible outbreak of legionnaire' disease. We drew the following conclusions from our experience with this and other cases that we saw during the legionnaires' outbreak: an atypical presentation is common, as seen in this lady with confusion. If two cases of atypical pneumonias test positive for legionella within a period of a week, we suggest that public health authorities should be notified to identify the source and contain it. There is a need for continuous and high vigilance for legionnaires' disease.
