Dengue is a public healthcare problem known in Brazil for an extended period, with the mosquito Aedes aegypti as its vector. In addition, it is a disease that affects all Brazilian territory, presenting, at times, an epidemic, endemic, and outbreak behavior. During the pandemic period of COVID-19, the number of Dengue notifications dropped drastically, inversely proportional compared to SARS-COV-2 numbers. Given this data, the present study aims to relate the notification downfall of Dengue with the pandemic timelapse, thus verifying a possible sub-notification or actual retraction of contamination by Dengue in Brazil, considering sociodemographic and clinical variables. Between 2017 and 2019, there is an acknowledged variation of 241.880 to 1.553.546 in Dengue cases. On the other hand, between 2019 and 2021, the value dropped to 544.765, presenting a predominance in the southeast and center-west. Hence, the idea of sub-notification of Dengue cases, considering the public health emergency estate presented by COVID-19, and the actual retraction of contamination by Dengue virus represent the two possible theories for the epidemiological situation presented by this study.
