摘要
目的分析黑龙江省布鲁氏菌病(布病)疫情,探讨不同时期影响该病疫情的可能因素。方法收集1949-2009年黑龙江省布病监测数据和文献中相关数据,对布病在不同时期、人群、年龄、性别、季节和地区分布情况进行描述性统计分析。结果 1949-2009年共出现3次布病发病高峰。20世纪50年代第1次发病高峰波及全省13个地市,其中1956年发病率最高,为6.87/10万;病例职业构成中农民最高,平均占81%左右;2000年以后出现2次发病高峰,2005年(发病4040例)为10.77/10万,2009年(发病4795例)为12.59/10万。病例职业构成除了农民以外,还涉及城市多种职业人群。结论黑龙江省布病发病率呈现老疫区持续高发、新疫区逐年增加态势;传染源以染疫羊为主,受威胁人群扩大,防控形势严峻。
Objective To analyze the epidemiological characteristics of brucellosis in Heilongjiang and explore the influence factors to the disease in different periods. Methods The descriptive epidemiological analysis was conducted on the incidence data of brucellosis in Heilongjiang from 1949 to 2009 to understand its population, age, gender, seasonal and geographic distributions in different periods. Results Three incidence peaks of brucellosis occurred from 1949 to 2009. The first one occurring in 1950s affected the whole province, the incidence in 1956 was highest （6. 87/lakh）. Most cases were farmers （ about 81% ）. Two incidence peaks occurred in 2000s, 4040 cases were reported in 2005 with the incidence of 10. 77/lakh and 4795 cases were reported in 2009 with the incidence of 12. 59/lakh. The disease affected not only farmers but also other populations in urban area. Conclusion The incidence of brucellosis in previously existed epidemic area continued to increase and more areas were being affected by the disease in recent years. Sick sheep are the major infection source and more population might be affected, indicating that prevention and control of the disease should be strengthened.
