Impacts of Climate Change on Dengue Risk in Brazil

This analytical report published by Inter-American Development Bank (IDB) identifies the climate impacts on dengue risk in Brazil by using a comparative case study on the synthetic controls approach. The results suggest that dengue is more prevalent in warmer regions, but the humidity conditions and amount of rainfall seem fundamental for increase of the diseases prevalence in temperate climate regions or drier tropical regions of the country. Due to expected climate changes in the future, the dengue fever distribution in the country might change, which requires public policy to minimize these effects.
