Information for health professionals
Legionnaires’ disease should be considered in patients who have been around the Broadmeadows area presenting with influenza-like symptoms such as headache, fever, rigors, cough or myalgia, and particularly those with atypical pneumonia. Rapid confirmation of the diagnosis of Legionella pneumophila serogroup 1 can be obtained by urinary antigen testing. (Two of these cases have been due to Legionella pneumophila serogroup 1). Sputum for culture should be sought in all cases if possible.
A four-fold rise in titre between acute and convalescent sera is also diagnostic, however, this may take two to four weeks to develop.
Legionnaires’ disease is a Group A notifiable condition which requires immediate notification to the Department by telephone on initial diagnosis (presumptive or confirmed) with written notification to follow within five days.
For further information or to notify a case please contact the Communicable Disease Prevention and Control Unit at the Department of Health on 1300 651 160 (business hours) or 1300 790 733 (after hours) or go to the Bluebook website.
