The transmission of dengue fever is linked to climatic and weather variables such as temperature, relative humidity and rainfall . The dengue virus is carried and spread by Aedes mosquitoes, primarily Aedes aegypti. Dengue has the second highest burden of VBDs, with the majority of deaths occurring in Asia . Since 1950, global dengue burden has grown and is attributable to a combination of climate-associated expansion in the geographic range of the vector species and non-climatic factors such as globalised air traffic, urbanisation and ineffective vector abatement measures. Temperature, relative humidity and rainfall variables are significantly and positively associated with increased dengue case incidence and/or transmission rates globally, including in Vietnam , Thailand , India , Indonesia , the Philippines , the USA , Jordan  and Timor-Leste . Variation in winds, sea surface temperatures and rain over the tropical eastern Pacific Ocean  have been linked to increased dengue incidence in Colombia  and its interannual variation successfully forecasted in Ecuador using ENSO indices as predictors . The observed time lag between climate exposures and increased dengue incidence is approximately 1-2 months .
