On this slide, you can see pictures of dehydrated patients coming to our hospital from six to three years ago. We can see people lying down with many IV fluids going through them to rehydrate them when they have this very severe dehydrating disease which we call cholera. I would like to talk about the work on cholera, especially that has been carried out at icddr,b, but also, other work from our Mucosal Immunology and Vaccinology Department, MIVU, within the infectious disease division of the center, and share it with our friends globally.

We are living in a time of extreme natural and manmade turbulence, climate change, pandemics, floods, tornadoes, earthquakes, tsunamis, humanitarian conflicts, and so on. We are facing many problems, and we are sure that in the future, it will not be less, and it might be more. In a country like Bangladesh, we have rising sea levels. The prediction is one million maybe displaced by 2050, from south of Bangladesh. Bangladesh has many rivers, covered by the sea and the rivers. The salinity, coastal inundation, and storm surge height is increasing. We feel that it will impact agriculture, food security, disaster management, health, drinking water supply, coastal infrastructure, and most of all, the risk of infectious diseases, of which cholera is not the least, but also, the most. All this leads to a lot of rainfall, increase in temperatures. Like last year in Southern Bangladesh, we had Cyclone Remal. Then there's so much salinity that people are without drinkable water everywhere. This is the story of cholera. Then people move from villages to urban slums, and there, the living condition is worse. There is less safe drinking water, sanitation is missing, and people come down with diseases, diarrhea, and of course, cholera. We have been carrying out research at icddr,b
