Three cases of imported Legionnaires' disease are reported. All 3 patients became ill after their return to Denmark from a holiday tour in northern Italy. High titers of antibodies to Legionella pneumophila in the indirect immunofluorescence (IF) test confirmed the diagnosis. The fact that the onset of illness was within 10 days of the last day the patients spent in Italy strongly suggests that the disease was imported to Denmark from Italy. 10 of the 77 tourists who participated in the study had IF titers of at least 256. Of these 6 had clinical signs of Legionnaires' disease. An additional case of legionella infection occurred months after the case described in this report and was probably contracted in Italy.
报告了3例输入性军团病病例。所有3名患者都是在从意大利北部度假旅行返回丹麦后发病的。间接免疫荧光（IF）试验中针对嗜肺军团菌的抗体高滴度证实了诊断。发病时间在患者在意大利度过的最后一天之后10天内，这一事实强烈表明该病是从意大利输入丹麦的。参与该研究的77名游客中有10人的IF滴度至少为256。其中6人有军团病的临床症状。在本报告所述病例之后数月又发生了1例军团菌感染病例，可能是在意大利感染的。
