Study on interictal period for animal plague foci in Hebei province

目的探讨河北省鼠疫自然疫源地鼠疫流行的静息期,为河北省鼠疫防治工作提供依据。方法 1981-2013年在河北省鼠疫自然疫源地,采用夹日法捕获长爪沙鼠,采用一日弓形夹法捕获达乌尔黄鼠进行调查,计算宿主动物密度;查阅鼠疫历史资料,确定流行年份。结果河北省鼠疫自然疫源地以2002年宿主动物密度最高,为4.75只/hm^2。河北省鼠疫自然疫源地在1971-2015年间共发生4次动物鼠疫流行,涉及8个流行年份,即1971、1972、1984、1994、1995、2002、2003和2005年,平均约10年流行一次。结论河北省鼠疫自然疫源地动物鼠疫流行静息期客观存在,约10年。
