In recent decades, epidemics emerging and reemerging diseases have mobilized public health and research institutions around the world. In this context, dengue, Zika and chikungunya arboviruses, transmitted by the vector Aedes aegypti have gained importance due to the high potential of transmissibility and the impact on the morbimortality of the population of several countries, such as Brazil. Studies on spatial diffusion aim to identify patterns of how a disease or phenomenon moves in time and space. Several authors have investigated patterns of spatial diffusion of dengue fever, its vector and viruses that cause this disease. There is, however, a gap in the understanding of the diffusion of dengue, Zika and chikungunya, once the simultaneously occur in the same territory. This research aimed to identify the diffusion patterns of Zika, dengue and chikungunya in municipality of Duque de Caxias during the epidemics from November 2015 to May 2016.
