Methodology


Because Bangladesh is expected to be one of the countries most affected by climate change, it is important to understand the various outcomes of the projected changes in climate.

Water availability will certainly be affected by projected climate change, yet the effects of this in terms of household responses and cholera have not yet been studied. Furthermore, cholera transmission routes are still poorly understood and the true burden of the disease is unknown.

Most studies rely on clinic and hospital-based surveillance, which miss the more frequent mild and moderate infections. These mildly and moderately symptomatic cholera infections are thought to play an important role in the spread of the disease.

By investigating the unknown characteristics of cholera and outcomes of climate change, interventions and policy can be more effectively targeted for cholera prevention and control and control in Bangladesh. 

This study will measure the incidence of cholera infections at the household-level within a cohort of 400 people over the course of two years, adding to a better understand of the burden of the disease in urban Bangladesh. 

Furthermore, it will analyze the associations between cholera, water stress, -quality and -hygiene and sanitation behaviors in order to make projections on how future water stress scenarios could influence the incidence of cholera in Bangladesh.
