OCORRÊNCIA E TRANSFORMAÇÕES SOCIOAMBIENTAIS DE ZOONOSES NA ÁREA DE INFLUÊNCIA DA USINA HIDRELÉTRICA CANA BRAVA - GO.

Abstract

This study aimed the evaluation of a possible interference of the construction of the Cana Brava hydroelectric power plant on the cases of zoonoses in the municipalities of Cavalcante, Colinas do Sul and Minaçu, which are under its direct influence. The occurrence of zoonoses, demographic conditions, morbidity, fauna of medical importance and the use of soil were taken into consideration in the three counties mentioned above. The information was obtained from existing official sources as DATASUS, IBGE, SINAN, IBAMA, INPE, PROBIO, and Naturae. The results were analyzed through statistic tests (ANCOVA). It was identified that morbidity rates have increased from 1995 to 2007 in the three municipalities, which is equivalent to the previous and posterior period of the installation of the power plant construction. According to DATASUS, 982 cases of Dengue Fever, 1 case of Chagas Disease, none of Yellow Fever, 234 cases of LTA, 4 cases of LV, and 17 cases Malaria were diagnosed in the three counties from 2001 to 2011. Two vectors of Dengue Fever, 7 vectors of Yellow Fever, 3 vectors of LTA, and 3 vectors of Malaria were found in the area. Two hosts of Chagas Disease, three of Yellow Fever, 1 of LTA, 2 of LV and 1 of Malaria were also found. The profile of the use of the soil shows the intensification of farming and cattle raising activities in the three counties along the years. The research presented some restrictions, mainly on the divergence of data and trends that were made public by numerous agencies. Although the acquired results of this research show some changes on the impact of diseases that appear in the region, these estimates and figures may show patterns of normality. The information obtained may not be sufficient to prove a linkage between the construction of the Cana Brava hydroelectric power plant and the status and trends of zoonoses in the three municipalities.
