目標：台灣退伍軍人症首次報告發生在1983年，並在1999年列為法定傳染病，本論文整理1999-2007年資料，以勾繪退伍軍人症在台灣公衛防疫的整體成果。方法：從1999年1月1日至2007年12月31日止，由疾病管制局傳染病倉儲系統收集原始資料，加以統計分析。結果：由1999年至2007年，總計通報病例數共11,205例，確定病例數563例，死亡數6人。確定病例每十萬人口發生率，分別是0.10、0.29、0.18、0.34、0.48、0.47、0.17、0.24和0.24，平均每十萬人口發生率為0.28。通報作業時效以日距平均數表示，從1999年平均為10.45日，至2007年平均為5.67日。檢體採檢率不論醫院層級或年代均達9成以上。檢驗陽性率由1999年平均1.34%，增至2007年10.51%。疫情調查完成率由1999年幾乎沒有實施(0.33%)，至2007年58.70%。結論：雖然在通報作業時效、檢體採檢率和檢驗陽性率方面，退伍軍人症防疫管理方面均有明顯進步，但在疫情調查完成率方面仍有可改善空間。

Objectives: The first case of Legionellosis in Taiwan was reported in 1983. In 1999, the government of Taiwan classified Legionellosis as a notice infectious disease. This study evaluated the prevention and control of Legionellosis in Taiwan using data from 1999 to 2007. Methods: Data on Legionellosis were collected for the years 1999 to 2007 from the notice infectious disease information system of Taiwan's department of disease control. The data were subjected to statistical analysis. Results: A total of 11,205 cases of Legionellosis were reported in Taiwan from 1999 to 2007. Only 563 cases were confirmed, and 6 people died because of the disease. The incidence rates for the 9 years of the study were 0.10, 0.29, 0.18, 0.34, 0.48, 0.47, 0.17, 0.24, and 0.24 per 100,000 population, respectively, with an average rate of 0.28. The mean effective of notice work was 10.45 per day in 1999 and 5.67 per day in 2007. The sampling rate was more than 90%. The mean positive rate increased from 1.34% in 1999 to 10.51% in 2007. The epidemic survey rate increased from 0.33% in 1999 to 58.70% in 2007. Conclusions: The notification work effectiveness, the sampling rate, and the positive rate in the prevention and control of Legionellosis showed obvious progress from 1999 to 2007, but the epidemic survey rate still had room for improvement.
