Dengue spatial and temporal patterns, French Guiana, 2001.

摘要: To study a 2001 dengue fever outbreak in Iracoubo, French Guiana, we recorded the location of all patients’ homes and date when symptoms were first observed. A geographic information system was used to integrate patient-related information. The Knox test, classic space-time analysis technique, detect spatiotemporal clustering. Analysis relative-risk (RR) variations space time distances vary, highlighted maximum extent transmission focus. results show that heterogeneity RR corresponds known entomologic epidemiologic factors, such as mosquito feeding cycle host-seeking behavior. This finding demonstrates relevance potential use GIS spatial statistics for elaborating surveillance strategy.
