中文摘要:

1997年6月北京某写字楼员工发生一起上呼吸道感染样(上感洋)疫情。为查明爆发原因, 采用流行病学病例-对照调查研究方法, 分别对病例组、对照组进行嗜肺军团菌(Lp)抗体1～14型血清学检测, 并对大厦空调系统采样进行细菌学培养检测。结果:该次爆发疫情的扁桃体炎罹患率为61.86%, 上感罹患率34.62%, 统计学检验发热与扁桃体关系密切(χ²=77.88, P<0.01);上感病例Lp9、10、12、14四型抗体阳性率为45.94%, 四组对照前述四种抗体的阳性比例分别为3/15、6/17、0/15、0/16;空调冷凝水培养Lp阳性。证明这是一起以空调系统为媒介由Lp9、12引起的上感样军团菌病爆发。

英文摘要:

An outbreak of upper respiratory infection (influenza-like syndrom) took place among the staff members of a large office building in Beiiing, June, 1997. To understand the cause of the outbreak, with a case-control study with serological antibodies detection against serogroup 1 to 14 of Legionnaires' disease bacteria (LDB) and bacteriological test and culture on samples collected from the air-conditioning system of the office building was performed. The findings showed that the attack rates of tongillitis and upper respiratory infection were 61.86% and 34.62% respectively. The relation was statistically significant between the symptoms of fever and tonsillitis in the cases (χ² =77.88, P0.01). The positive rates of LDB antibodies on serogroups 9, 10, 12, 14 were 45.94% in the cases of upper respiratory infection and 3/15, 6/17, 0/15, 1/16 respectively in the four controls groups. Condensied water samples from an air-conditioning system showed that Legionella Pneumophila was positive. Evidence showed that it was an outbreak resulting from LDB serogroup 9 and 12, accompanied by upper respiratory infection related to air-conditioning system contaminated by LDB. This was the first report Lp infection associated with an air-conditioning system in Cbina.
