Abstract
- Cystic echinococcosis (CE), which is caused by Echinococcus granulosus, is a worldwide helminthozoonosis that is highly endemic in the Tibet Autonomous Region of China and has important public health and economic impacts. However, the spatial epidemiological characteristics of CE in Tibet are still unclear. Based on recorded human CE cases and the use of a geographic information system, the spatial distribution patterns of CE prevalence at three different scales were analyzed. In addition, a spatial agglomeration map of CE prevalence was generated based on cold/hot spot analysis. By combining maps of environmental and biological covariates with information about known human CE cases, the links between CE prevalence and relevant covariates were explored, revealing that the annual average precipitation, elevation, water accessibility and animal population (dog and yak) were associated with the prevalence of CE at the significance level of P
