Dengue is caused by an RNA virus, which has 4 identified variations present in the human environment. Its main symptomatological manifestations include fever, muscle pain (myalgia), retro ocular pain, joint pain (arthralgia), headache (headache), nausea, vomiting and others, such as rash. This article aims to show the number of confirmed dengue cases in Brazil between 2008 and 2012. In Brazil, dengue is characterized as a major public health problem, being one of the diseases of an infectious nature that is very present. Some factors, such as the climate (predominantly tropical), deficient infrastructure of the urban environment, in addition to demographic expansion, which occurs in a disorderly manner, can provoke and possibly justify this national scenario. It represents a major public health problem, since the control of the disease depends on the fight against its vector, which spreads very easily in the country, due to climatic and anthropic factors. For the disease to be tackled efficiently in the country, the most effective method is to combat the vector. Garbage and materials must be efficiently separated and stored in suitable locations for further recycling, so that they do not accumulate water and become mosquito breeding sites.
