May 9, 2024 · The model reproduced an extensive outbreak in 2015–2016 and substantially reduced dengue epidemics worldwide in 2017–2018, which coincided with the occurrence of a warm IOBW event in 2015–2016 and a cold IOBW event in 2017–2018 . Wavelet coherence between the observed and estimated dengue cases reveals that the model effectively ...
