Abstract: Objective To study the main way of discovering commensal rodent plague foci amid host rodents in Yunnan province in 1999-2004. Methods The proportion of the foci 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 foci 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 foci 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 foci.
