Climate and Dengue Transmission: Evidence and Implications

Cory W. Morin, Andrew C. Comrie, and Kacey Ernst
Environmental Health Perspectives
  • States relationships between climate variables and factors that influence dengue transmission are complex; a climate variable may increase dengue transmission potential through one aspect of the system while simultaneously decreasing transmission potential through another
  • States this complexity may at least partly explain inconsistencies in statistical associations between dengue and climate
  • Finds that although climate variables strongly influence DENV and its vectors, caution must be taken when using only one element or connection to predict disease occurrence
  • Finds that synthesizing and applying current knowledge of climatic effects on all aspects of dengue virus ecology will help direct future research and enable better projections of climate change effects on dengue incidence
