Spatial distribution of dengue disease in municipality of Mossoró, Rio Grande do Norte, using the Geographic Information System

Abstract

The dengue viral infection is one of the most relevant vector-borne diseases in the world. The disease can manifest in a variety of forms, from asymptomatic to a condition of dengue hemorrhagic fever (DHF). The last reported cases in Brazil correspond to 80% of the cases reported in the Americas, which emphasizes the magnitude of the problem. This study was conducted using Geographic Information System (GIS) techniques, in order to evaluate the spatial distribution of the disease in the urban area of Mossoró, Rio Grande do Norte. In the period between 2001 and 2007, 867 new cases were listed. About 85.7% of the addresses were georeferenced, with a larger number of cases, 14.8%, in the neighborhoods of Santo Antônio and Santa Delmira (north region), and 11.7% in the neighborhoods of Conjunto Vingt-Rosado and Alto de São Manoel (east region). There were 18 confirmed cases of dengue hemorrhagic fever associated with regions with the highest incidence of classic cases of the disease. The use of Geographic Information System (GIS) proved a great benefit for better visualization of the endemic, especially in elucidating the actual distribution of dengue cases in the county and providing an effective tool for planning the monitoring of the disease at a local level.

Epidemiological study on dengue in southern Brazil under the perspective of climate and poverty

“…Likewise, the calculated maximum correlation between rainfall and dengue cases in Sri Lanka from 2003 to 2012 and in Bangladesh from 2010 to 2014 presented a lag of two months 73,75 . A delay of two months between maximum values of the monthly rainfall and dengue cases was also observed in Pirapora and Mossoró, two cities located respectively in the Southeast and Northeast Regions of Brazil 76,77 . The three month delay between rainfall and dengue incidence observed in our study, which is about one month higher than those described above, may be explained by the relatively lower average annual temperature of Cambé.…”

Caracterização Dos Casos De Dengue Por Localização No Interior De Mato Grosso Entre 2007 E 2016

“…Neste contexto, o estudo da caracterização da localização da dengue fornece informações que não seriam visualizadas trabalhando apenas com dados tabulares, percebendo-se a importância desta distribuição quando se pretende analisar a localização geográfica dos focos de dengue em períodos endêmicos, para tentar intervir de maneira a minimizar as ocorrências e na busca pela erradicação do vetor através do conhecimento de seu habitat (7) .…”

“…A melhoria das condições higiênico-sanitárias das habitações, coleta apropriada do lixo e fornecimento de água encanada são medidas também importantes no controle da dengue. Ademais, estudos em diferentes latitudes, temperaturas, condições ambientais e sanitárias que visem ao monitoramento dos vetores transmissores dos vírus da dengue tornam-se ferramentas importantes para a melhoria dos programas de controle, uma vez que o controle vetorial é o único método de prevenir epidemias da dengue [27][28][29][30][31] .…”
