Dengue epidemics occur typically in the warmest months without qualitative differences for the Brazilian geographic regions. However, this disease has an important quantitative difference. We observe two clusters in the country regarding the number of case notifications: The first cluster is formed by the North-East and South-East regions, that sum about 86% of the all notifications; and the second is formed by the South, North and Center-West regions. Vector index were associated to the population sizes, and most of them were below of the recognized threshold index for epidemics risk although epidemic situation were observable in some of these places. Apparently, there was no positive evidence between dengues epidemics and vector index.
登革热疫情通常发生在最温暖的月份，巴西各地理区域之间没有质性差异。然而，这种疾病存在重要的量的差异。在该国，就病例通报数量而言，我们观察到两个集群：第一个集群由东北部和东南部地区组成，这两个地区的通报量约占所有通报的86%；第二个集群由南部、北部和中西部地区组成。病媒指数与人口规模相关，尽管在其中一些地方可观察到疫情形势，但大多数病媒指数低于公认的疫情风险阈值指数。显然，登革热疫情与病媒指数之间没有确凿证据。
