Experts’ opinion

Experts attribute the unusually high dengue cases during the dry season, mainly in Dhaka, to the prolonged rainy season, sporadic rainfall, and high humidity and temperature, Aedes mosquitoes' reproductive and behavioural changes caused by climate change and lack of people’s awareness and poor controlling measures by the two city corporations of the capital.

They also said the climate conditions of Bangladesh are becoming more favourable for the Aedes mosquitos to prevail in all seasons with high or low intensity mainly for the increase in temperature and breeding sources.
