Socio-demographic and environmental determinants of morbi-mortality due to dengue in Singapore, in Southeast Asia: a comparison with the Brazilian case

Dengue fever is a global public health problem and requires efforts to be understood and controlled. It is estimated that fifty million dengue cases occur every year in more than 100 countries. Approximately two and a half billion people live in areas where dengue is endemic, which happens mainly in Asia, Africa and South America. We aim to understand in this paper: 1) What are the main socio-demographic and environmental determinants of morbidity and mortality due to dengue in Singapore?; 2) In a comparative analysis, what are the differences between the causal factors of dengue in Singapore in relation to those found in Brazil?; 3 ) Why is this an issue so difficult to equate to theses two countries public health authorities?; and 4) What are the feasible and effective policies that can be implemented in these distinct contexts? These issues will guide the present study, in which we will highlight the role of demographic dynamics (mainly morbidity, mortality and migration), besides the urban environmental sanitation conditions, to find explanations for this difficult problem to solve according to what global experience showed so far.
