A study was undertaken to analyse legionellosis notifications for the period 1991 to 2000 to establish the distribution of legionellosis in Australia with the aim of identifying risk factors amenable to public health intervention. Legionellosis notification rates ranged from 0.6 cases per 100,000 population in 1991 to 2.5 cases per 100,000 population in 2000. Notifications were highest in autumn (March to May). Sixty-nine per cent of cases were males. At-risk population included those aged over 50 years. The upward trend in notification rates of legionellosis indicated that this disease remains a significant public health problem particularly among older people. Seasonal differences in notification rates require further investigation to develop appropriate prevention and control strategies. To have a better understanding of the epidemiology of legionellosis, further information is needed on smoking history, chronic illnesses, whether the notification is outbreak-related and the species of Legionella isolated.
开展了一项研究，分析1991年至2000年期间军团病的通报情况，以确定澳大利亚军团病的分布情况，目的是找出适合公共卫生干预的风险因素。军团病通报率从1991年的每10万人0.6例到2000年的每10万人2.5例不等。秋季（3月至5月）的通报数最高。69%的病例为男性。高危人群包括50岁以上的人。军团病通报率的上升趋势表明，这种疾病仍然是一个重大的公共卫生问题，尤其是在老年人中。通报率的季节性差异需要进一步调查，以制定适当的预防和控制策略。为了更好地了解军团病的流行病学，还需要有关吸烟史、慢性病、通报是否与疫情相关以及分离出的军团菌种类的更多信息。
