Four months into the Rohingya humanitarian crisis, the flow of refugees continues. More than 655,000 Rohingya people have fled to Cox’s Bazar, Bangladesh since 25 August 2017. Settlements are overflowing and the concentration of refugees is amongst the densest globally. More than half the arrivals are women and girls. Already marginalized and vulnerable, they are bearing the brunt of the crisis. UNFPA is spearheading lifesaving efforts to respond to the acute health and protection needs of women and girls amid this crisis, as well as planning for the protracted situation ahead.
