In Burma, where 90% of the population is Buddhist, the Rohingya Muslim minority is deprived of citizenship. Since the summer of 2017, more than 700,000 Rohingyas have crossed the border into Bangladesh heading for the Kutupalong-Balukhali, Jamtoli, Unchiprang and Nayapara camps where a million people already live.
These camps are among the most heavily populated in the world, although the flow of refugees has slowed since 2018.
Médecins Sans Frontières (MSF) organizes access to first aid and sets up sanitation facilities to ensure a water supply and prevent the spread of disease.
An MSF partner, the Veolia Foundation provides its support and know-how by drilling wells in the camps - the first step to providing access to water.
