1999至2004年云南省家鼠型鼠疫鼠间疫点发现方式调查

目的探讨家鼠型鼠疫鼠间疫情的主要发现途径.方法通过对1999～2004年云南省捕获鼠及自毙鼠有关资料的比较以及对其不同地区和不同年份自毙鼠报告情况的比较,查明鼠间鼠疫疫点的发现途径.结果1999～2004年云南省家鼠型鼠疫所有鼠间疫点通过自毙鼠检测发现者占89.6%,通过捕获鼠检测发现的仅占10.4%.人间鼠疫病例多的县（市）和病例多的年份自毙鼠报告率显著低于病例少的县（市）和年份.结论1999～2004年云南省家鼠型鼠疫鼠间疫点主要是通过自毙鼠检测发现的,自毙鼠报告是发现鼠间疫情的主要手段.

An Investigation on the Manners of Finding Out Commensal Rodent Plague Foci Amid Animals in Yunnan Province in 1999-2004

Objective To study the main way of discovering commensal rodent plague loci amid host rodents in Yunnan province in 1999-2004. Methods The proportion of the loci detected with trapped rodents was compared with that of the self-dead rodents, and the self-dead rodent reporting rates were compared of different places and different years, in which different numbers of human plague cases occurred in Yunnan province in 1999-2004. Results Of all the loci those detected with self-dead rodent test reach 89.6% , whereas those detected with trapped rodent test only account for 10.4% . The self-dead rodent reporting rates in the counties or years with more human plague cases were significantly lower than those with less human plague cases. Conclusion The loci of rodent plague were found out mainly by self-dead rodent test in Yunnan province in 1999-2004, and self-dead rodent reporting was the main way to detect the loci.
