Dengue, a mosquito-borne tropical infectious disease, is gradually becoming an annual affair in Bangladesh as an endemic due to the adverse impacts of climate change, say experts. They also said Bangladesh’s climate conditions are becoming more suitable for dengue and other vector-borne diseases like malaria and chikungunya due to excessive and erratic rainfall, waterlogging, flooding, and rise in temperature and abnormal shifts in the country’s traditional seasons. The analysts think the government should focus on rigorous scientific research to understand the Aedes mosquitoes' reproductive and behavioural changes due to climate change and thus find out effective measures to contain it.
