| Summary: | Dengue is currently one of the most serious worldwide public health problems. It is a disease of the tropical world, in which most of Latin America is located and where the environment and climate provide ideal conditions for the Aedes mosquito (aegypti and albopictus) to thrive. In addition the socio-cultural environment (urbanization and lifestyle) and an ineffectiveness of public health policies, result in severe epidemics of the disease. This research aims to analyze incidences of dengue fever in three different cities in Brazil: Campo Grande/Mato Grosso do Sul, Maringa/Parana and Ribeirao Preto/São Paulo and its statistical relationship to climate by correlating different climate variables to dengue incidence. Daily temperature analysis also shows significant correlation (R=0.70 and P>0.99) with disease incidence subject to a 7 days lag. In addition to climate and environmental factors, the mobility of population through by imported cases, has also been investigated. The results show the complexity of disease, in a strict relation between the environment (weather) and the mobility of the population, the circulation of different serotypes, the disposal of solid waste, debris and abandoned swimming pools, consequence ofthe indifference of the population to situations of risk and vulnerability to the disease. An important point to highlight is that, even in different cities, the epidemics followed a similar pattern, emphasizing the importance of climate variables (should also add the hypothesis of travel, serotype). Our study uncovered important relationships between dengue epidemics and climate, although more detailed studies on both serotype and transmission in cities are necessary to further understand the factors behind disease transmission. Our results could assist local health agencies on implementing appropriate early warning systems monitoring and preventive control actions by monitoring temperature conditions prior to the epidemics.Key words: Dengue, climate, society, Centro-south, Brazil |
