Multifaceted international and national collaborative responses and progress have sustained the world’s largest densely populated refugee camps in the Cox’s Bazar district, Bangladesh. Yet, the Rohingyas remain in an extremely precarious situation during the COVID-19 pandemic. The refugees are living in highly challenging circumstances of water, sanitation, and hygiene (WASH), natural disasters of the monsoon season as well as existing health and educational challenges of HIV, malnutrition and other diseases. Particulate matter PM_2.5 in the sampling camps varied from 44 μg/m³ to 546 μg/m³, whereas PM₁₀ in the sampling camps varied from 125 μg/m³ to 1122 μg/m³. Due to lock-down of Cox’s Bazar, aid workers in and out of the camps were restrained with the only continuation of emergency food and medical service supplies. Largely dependent on aid during the ongoing pandemic, an investigation of the socio-environmental challenges of the refugee camps will identify the anticipatory impacts and needs.

多方面的国际和国家合作反应和进展维持了孟加拉国科克斯巴扎尔地区世界上最大的人口稠密难民营。然而，在 COVID-19 大流行期间，罗兴亚人仍处于极其危险的境地。难民生活在水、环境卫生和个人卫生 (WASH)、季风季节自然灾害以及艾滋病毒、营养不良和其他疾病等现有健康和教育挑战的高度挑战环境中。采样营地的颗粒物 PM _2.5从 44 μg/m ³到 546 μg/m ³不等，而采样营地的 PM ₁₀从 125 μg/m ³到 1122 μg/m ^3不等. 由于考克斯巴扎尔的封锁，进出营地的救援人员受到限制，只能继续提供紧急食品和医疗服务供应。在持续的大流行期间很大程度上依赖于援助，对难民营的社会环境挑战的调查将确定预期的影响和需求。
