Health researchers predict that the transmission of dengue could decrease in a future warmer climate, countering previous projections that climate change would cause the potentially lethal virus to spread more easily.Hundreds of millions of people are infected with dengue each year, with some children dying in severe cases, and this research helps to address this significant global health problem.Co-lead researcher Associate Professor David Harley from The Australian National University (ANU) said that dengue risk might decrease in the wet tropics of northeast Australia under a high-emissions scenario in 2050, due to mosquito breeding sites becoming drier and less favourable to their survival.
