In August 2017, the Rohingya genocide erupted into a global refugee crisis, as a large number of Rohingya refugees fled Myanmar for Bangladesh. This global public health epidemic carries a significant mental health impact. Myanmar's combat situation, trauma, as well as post-migration situations such as resettlement camp environments, could lead to serious mental health issues. The purpose of this study was to learn more about the children's experience in Myanmar from Bangladesh's Kutupalong refugee camp in Cox's Bazar, as well as their present mental health situation. The research was designed as a qualitative study, and 13 children were chosen as participants. The study was completed in 2018. The information gathered was transcribed, triangulated, and thematically analysed. Post-traumatic stress disorder (PTSD), anxiety, depression, and somatic symptoms were all cited by the majority of respondents. They frequently suffered from flashbacks, nightmares, panic attacks, suicidal ideation, trauma, palpitation, sleep disturbances, and physical aches for no apparent reason. Because of the time restrictions, this study was able to produce concise results. This research could aid in understanding potential mental health interventions for Rohingya refugee children.
