Rising temperatures and a longer monsoon in Bangladesh because of climate change are providing ideal breeding conditions for the dengue-spreading mosquito, experts said, as the country grapples with its worst-ever outbreak of the viral disease. The death toll from Bangladesh's outbreak in 2023 is 1,476 as of November 12, with 291,832 infected, official data showed. Hospitals have struggled to cope with the rising number of patients in the densely populated South Asian country.
