0083/2018 - Using satellite data to study the relationship between rainfall and diarrheal diseases in a Southwestern Amazon basin . O Uso de dados de satélite para estudar a relação entre chuva e doenças diarreicas em uma bacia na Amazônia Sul-Ocidental.
A região Norte é a segunda no Brasil com a maior taxa de incidência de doenças diarreicas em crianças menores de 5 anos. O objetivo desse estudo foi investigar a relação entre chuva e nível do rio principalmente durante a estação chuvosa com a taxa de incidência da referida doença em uma bacia no sudoeste da Amazônia. Estimativas de chuva e nível do rio foram correlacionadas entre si e ambos correlacionados com a taxa de incidência da diarreia. Para a região do Alto Acre, 2 a 3 dias de defasagem é o melhor intervalo para observar o impacto da chuva no nível do rio (R=0.35). Na região do Baixo Acre essa defasagem aumentou (4 dias) e uma pequena redução na correlação foi encontrada. A correlação entre chuva e doenças diarreicas foi melhor na região do Baixo Acre (Acrelândia, R=0.7) e a chuva rio acima da cidade. E entre o nível do rio e as doenças diarreicas, os melhores resultados foram encontrados para a estação de Brasiléia (casos em Brasiléia, R=0.3 e Epitaciolândia, R=0.5). Os resultados desse estudo podem dar apoio ao planejamento e alocação de recursos financeiros para priorizar ações para Defesa Civil e serviços de saúde antes, durante e depois da estação chuvosa.
The North region is the second region in Brazil with the highest incidence rate of diarrheal diseases in children under 5 years old. The aim of this study was to investigate the relationship between rainfall and water level during the rainy season mainly with the incidence rate of this disease in a southwestern Amazon basin. Rainfall estimates and the water level were correlated between each other and both of them were correlated to the diarrheal incidence rate. For the Alto Acre region, 2 to 3 days’ time-lag is the best interval to observe the impact of the rainfall in the water level (R=0.35). In the Baixo Acre region this time-lag increased (4 days) and a slightly reduction in the correlation value was found. The correlation between rainfall and diarrheal disease was better in the Baixo Acre region (Acrelândia, R=0.7) and rainfall upstream the city. And between water level and diarrheal disease, the best results were found for the Brasiléia gauging station (Brasiléia, R=0.3; Epitaciolândia, R=0.5). These study\'s results may support planning and financial resources allocation to prioritize actions for local Civil Defense and health care services before, during and after the rainy season.
