Explosive outbreaks of dengue fever have rapidly spread in countries across Asia, killing more than 1,000 people, infecting hundreds of thousands and straining hospitals packed with sick families.
Images from Bangladesh show patients in teeming hospital wards, lying beneath mosquito nets under lurid electric strip lights.
Mothers cool their children from the sticky summer heat with hand-held fans while others rest on hospital floors, holding drips, waiting for a free bed.
This is the worst outbreak Bangladesh has ever seen. Five times as many people were infected in August than the whole of 2018, and so far this year 57 people have died.
