INTRODUCTION: Dengue is a febrile infectious disease caused by a virus and transmitted by the bite of the female Aedes aegypti mosquito, the main vector of the disease. The etiological agent of dengue is an arbovirus of the genus Flavivirus, which belongs to the Flaviviridae family. There are four variations or serotypes: Den-1, Den-2, Den-3 and Den-4. In this article the epidemiology of Classic Dengue will be portrayed, which symptoms can be felt for approximately 6 days and the main ones are: fever, headache, pain in the body, joints and behind the eyes, nausea and vomiting. AIM: To determine the epidemiological profile of cases of admission for Dengue fever in Brazil during the last year. MATERIAL AND METHODS: This is an epidemiological, quantitative and retrospective study with data collection in the Department of Information Technology of the Unified Health System (SUS) - DATASUS. The study was conducted using epidemiological information and morbidity with consultation of the SUS Acute Notification Information System (SINAN NET) of the Brazilian Ministry of Health. The data available in the system were analyzed, such as: number of hospitalizations, mortality rate, etc. RESULTS: From April 2019 to April 2020 there were 62.491 hospitalizations of clinical cases of Dengue in Brazil. The Southeastern region, due to the higher concentration of people, represented 39% of these hospitalizations. The mortality rate caused by Dengue fever in Brazil in the last year was less than 1% and most of the individuals who died are elderly, which is a group at risk. In April 2019, cases of Dengue fever increased exponentially, and after two months the disease suffered a notable reduction, but in February 2020, it was noticed that the cases grew again, and 7048 hospitalizations caused by Dengue fever were reported.  CONCLUSION: The trend of Dengue outbreaks in Brazil is high, this fact can be justified by the tropical equatorial climate prevailing in Brazil. The excellent support provided by SUS contributes to an exponential decrease in mortality rates associated with this disease, especially among the elderly. Due to the COVID-19 pandemic, Dengue has been neglected currently causing an increase in the number of cases. Thus, it is remarkable that it is necessary to increase campaigns to prevent and combat the Aedes aegypti mosquito.
