登革热流行通常发生在最温暖的月份，巴西各地理区域之间没有质的差异。然而，这种疾病有一个重要的数量差异。我们观察到该国关于病例通知数量的两个集群：第一个集群由东北和东南地区组成，占所有通知的86%;第二个集群由南部，北部和中西部地区组成。病媒指数与人群规模有关，虽然部分地区有疫情发生，但大部分地区的病媒指数低于流行病风险的公认阈值指数。登革热的流行与媒介指数之间没有明显的正相关关系。
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 epidemic's risk although epidemic situation were observable in some of these places. Apparently, there was no positive evidence between dengue's epidemics and vector index.
