In May 1997, a 3-year-old boy in Hong Kong died of a respiratory illness related to influenza A (H5N1) virus infection, the first known human case of disease from this virus. An additional 17 cases followed in November and December. A case-control study of 15 of these patients hospitalized for influenza A (H5N1) disease was conducted using controls matched by age, sex, and neighborhood to determine risk factors for disease. Exposure to live poultry (by visiting either a retail poultry stall or a market selling live poultry) in the week before illness began was significantly associated with H5N1 disease (64% of cases vs. 29% of controls, odds ratio, 4.5, P=.045). By contrast, travel, eating or preparing poultry products, recent exposure to persons with respiratory illness, including persons with known influenza A (H5N1) infection, were not associated with H5N1 disease.
1997年5月,香港一名3岁男童死于与甲型流感(H5N1)病毒感染相关的呼吸系统疾病,这是已知的首例感染该病毒的人类病例。11月和12月又出现了17例病例。对15名因甲型流感(H5N1)疾病住院的患者进行了病例对照研究,使用年龄、性别和社区匹配的对照来确定疾病的危险因素。发病前一周接触活禽(通过参观零售家禽摊位或活禽市场)与H5N1疾病显著相关(64%的病例与29%的对照,优势比为4.5,P = 0.045)。相比之下,旅行、食用或制备家禽产品、近期接触呼吸道疾病患者,包括已知感染甲型流感(H5N1)的患者,与H5N1疾病无关。
