Dengue em idosos: revisão de literatura.

Abstract

Dengue is characterized as an acute febrile disease, may present a mild and self-limiting clinical course as it progresses to a serious disease. It is one of the most important arbovirose that affects man, it is a serious public health problem in the world. The etiologic agent is an RNA virus, arbovirus of the genus Flavivirus, belonging to the family Flaviviridae. Currently 4 serotypes are known: DENV 1, DENV 2, DENV 3 and DENV 4. The vector is a mosquito of the genus Aedes. Dengue virus infection can be symptomatic or asymptomatic and presents a broad clinical aspect, when symptomatic causes systemic disease and can progress to severe conditions, as well as evolve to death. In view of the prevalence of arboviruses at certain times of the year, it is extremely important to seek the scientific literature as the dengue virus presents its clinical manifestations in the elderly, since an infection prior to the Dengue virus can help in a secondary infection by strains of the same virus and thus cause more severe manifestations in the elderly. This work presents the purpose of a literature review, aiming to Elencar the main clinical manifestations of dengue and possible complications related to the elderly, in national and international databases. It is a review of the literature with qualitative and descriptive characteristics, the search was done through the portals SCIELO, LILACS, MEDLINE, and BDENF. This study observes that there was an increase in the number of cases, especially during the years of 2008, 2009 and 2010, and this increase may be related to the climatic conditions, occurring mainly in rainy season, precariousness, influence of the absence of basic sanitation and also the growth during this period. Regarding the elderly, studies show that the prevalence in mortality rates in this age group presented a significant increase in relation to the general population affected by dengue. However, through the published scientific reviews we conclude that: Dengue is an arbovirose that presents great incidence in Brazil that affect the whole population, in all the age groups being more aggravating in the elderly, due to the alterations resulting from the physiological process of aging causing a decrease in reserve, defense and adaptation capacity making them vulnerable to infectious agents.
