In recent years, Dengue has become a serious public health problem for the Brazilian population, especially in urban environments. The disease is directly related to the proliferation and infestation index of the vector, which in turn depends on environmental factors that drives to its multiplication. In this sense, this study aimed to understand the causes of the significant increase of Dengue in Mato Grosso in the period between 2011 and 2015. So, we analyzed the temporo-spatial variation of cases of Dengue notifications provided by the State Department of Health, in order to investigate the hypothesis that such expressive increase of the disease in this period could be related, above all, to socioenvironmental conditions. It can be seen through the study that in the last few years there has been an alarming increase in the rates of dengue in most of the municipalities of the state of Mato Grosso and in all sectors of the territory of the state, and in those in which The weather rate has been very different.

The expansion of urban areas is leading people to adopt cats as pets as they are better adapted to the modern lifestyle, require smaller spaces and could stand alone for longer periods compared to other animals such as dogs. However, environmental groups are concerned about the increasing population of felines in urban areas, as they believe that cats threaten the lives of wild birds and small mammals that may be extinct. This research note presents pros and cons of cats' presence in cities as how to handle them. Correct management of these animals is necessary, since the greatest environmental risk related to their presence is their uncontrolled reproduction, and consequent abandoning of undesirable pups by their tutors.
