Abstract:
Plague is an anthropozoonotic disease caused by the Yersinia pestis,which developed by many factors including local climate factors.In recent years,more and more studies on the effects of climate on plague were conducted.According to the researches,climate factors (mainly the rainfall and temperature) affected the development and distribution of plague by influencing the abundance of plague host animals and fleas index.The climate also affected the epidemic dynamics and the scope of plague.There were significant differences existing in the influence of climate on the palgue developed in the north and south China.In the two different plague epidemic systems,the solitary Daurian ground squirrel-flea-plague and the social Mongolian gerbil-flea-plague,the obvious population differences existed among the responses of the host animal to the climate changes.Although the internal relationship between the rainfall,the flea index,the density of rodents and the plague supported the nutritional cascade hypothesis,it can not prove that there is a clear causality between the occurrence of plague and rainfall.So the influence of climate factors on plague distribution can only be used for early forecasting and warning of the plague.
