Dengue is an arbovirus infection whose etiologic agent is transmitted by the Aedes aegypti mosquito. Since the early 1980s, when the circulation of the dengue virus (DENV) was confirmed in Brazil, the disease has become a growing multifactorial public health problem. This article presented the main factors that have contributed to the frequent dengue epidemics in recent years, such as the behavior of the vector, climate change, and social, political, and economic aspects. The intersection between these different factors in the dynamics of the disease is highlighted, including the increase in the mosquito population due to higher temperatures and rainy periods, as well as the influence of socioeconomic conditions on the incidence of dengue. Some mosquito control strategies are also addressed, including the use of innovative technologies such as drones and the Wolbachia bacterium, as well as the hope represented by the dengue vaccine. Nevertheless, the need for integrated and effective public policies to reduce social inequalities and the impacts of climate change on the spread of dengue is emphasized.
登革热是一种虫媒病毒感染病，其病原体由埃及伊蚊传播。自 20 世纪 80 年代初巴西确认登革热病毒（DENV）传播以来，该病已成为一个日益严重的多因素公共卫生问题。本文介绍了近年来导致登革热频繁流行的主要因素，包括病媒的行为、气候变化以及社会、政治和经济方面。强调了这些不同因素在疾病动态中的交叉，包括由于高温和雨季蚊群数量增加，以及社会经济条件对登革热发病率的影响。还讨论了一些蚊虫控制策略，包括使用无人机和沃尔巴克氏体等创新技术，以及登革热疫苗带来的希望。然而，强调了需要采取综合有效的公共政策来减少社会不平等和气候变化对登革热传播的影响。
