Epidemia de dengue: fatores intervenientes e estratégias de prevenção

Abstract

Introduction: Dengue is an asymptomatic or symptomatic viral infection, transmitted through the bite of the female mosquito of the species Aedes aegypti. Symptomatic disease has several clinical changes and can progress to death. The first dengue epidemic recorded in Brazil occurred in Boa Vista (Roraima) in the years 1981- 1982. In the Midwest, the disease arrived in the mid-90s. Since then, epidemics of the disease have occurred frequently in the country. The Midwest region had a higher incidence of the disease, 1,196.1 cases / 100 thousand inhabitants. Objective: to identify in the scientific literature the intervening factors of the dengue epidemic, as well as the strategies to combat, prevent, mitigate and eradicate dengue. Method: integrative literature review carried out in the databases of the Virtual Health Library and Scielo with the following descriptors: dengue, epidemic, health profile. The study sample consisted of 11 scientific articles published between 2014 and 2019 on the theme, focusing on the Brazilian population and the Midwest region. Results and Discussion: the following categories were highlighted: epidemiological profile of dengue; factors involved in the dengue epidemic and dengue prevention strategies. Final considerations: it became evident that there is a need to deepen the issue of dengue, since the cases of the disease are on the rise, representing a serious public health problem.
