An outbreak of psittacosis related to a bird park occurred in Matsue City, Shimane Prefecture, Japan, during winter 2001. Seventeen cases of psittacosis (12 visitors, three staff, and two student interns) were confirmed. A cohort study was conducted among the park staff and students to determine the risk factors for the development of acute serologically confirmed psittacosis (SCP) infection. Being 'bird staff' had an increased risk of SCP infection (RR 3.96, 95% CI 1.48-10.58). Entering the staff building, where ill birds were maintained without proper isolation, was also associated with an increased risk of SCP infection (RR 3.61, 95% CI 1.03-12.6). Isolation of ill birds and quarantine measures were found to be insufficient. Dehumidifiers and a high-pressure water spray under a closed ventilation environment may have raised the concentration of Chlamydophila psittaci in the hothouses. Bird park staff and visitors should be educated about psittacosis.
2001年冬季，日本岛根县松江市发生了一起与鸟类公园相关的鹦鹉热疫情。确诊了17例鹦鹉热病例（12名游客、3名工作人员和2名实习学生）。对公园工作人员和学生进行了一项队列研究，以确定急性血清学确诊鹦鹉热（SCP）感染发生的危险因素。身为“鸟类工作人员”会增加SCP感染风险（相对危险度3.96，95%置信区间1.48 - 10.58）。进入饲养病鸟且未进行适当隔离的工作人员楼也与SCP感染风险增加有关（相对危险度3.61，95%置信区间1.03 - 12.6）。发现病鸟隔离和检疫措施不足。在封闭通风环境下使用除湿机和高压喷水可能提高了温室中鹦鹉热衣原体的浓度。应向鸟类公园工作人员和游客开展有关鹦鹉热的教育。
