SITUATION OVERVIEW

  • Violence in Rakhine State, Myanmar, which began on 25 August 2017 has driven an estimated 655 000 Rohingya across the border into Cox’s Bazar, joining some 300 000 that had fled in earlier waves of displacement. Pre-existing settlements and camps have expanded with the new influx, while new spontaneous settlements have also formed and grown.

  • The current outbreak is mainly occurring within the displaced Rohingya population living in the Balukali makeshift and extension camps. Cases are also being reported from the Kutupalong extension, Thangkhali, Jamtoli, and Nyapara camps. This population is also affected by malnutrition, low routine immunization coverage, and poor access to clean water and sanitation facilities.
