Abstract:

The Federal District (DF) has particular characteristics that favor the introduction, reproduction, dissemination and permanence of the dengue vector and viruses. The objective of this work was to analyze the spatiotemporal patterns of dengue epidemics in the Administrative Regions (ARs) of DFJanuary 2007 to December 2017. Using Fourier partial series model, we obtained a seasonal signature of the time series, which allowed to calculate indicators of permanence (number of epidemic years, number of epidemic months per year, the proportion of epidemic months of the period) and time/moment of epidemics (month of epidemic peak). There were a total of 82 epidemics in this period. The ARs with the largest number of epidemic years were Varjão (5 epidemics), Gama, Lago Sul and Sobradinho (4 epidemics). These last three ARs also had the highest proportions of epidemic months of the entire study period (9 epidemic months). The ARs with urban centrality function had an earlier epidemic peak than the others, in February and March. Epidemics showed high permanence values in ARs with different types of occupations, emphasizing the need to consider the processes of social organization of space in studies of dengue distribution.
