As the COVID-19 pandemic spreads worldwide, its adverse effects are becoming increasingly apparent among individuals affected by humanitarian emergencies. Overcrowding, limited access to preventative and preventative health services, poor water, sanitation, and hygiene services, poor governance, mistrust of officials, and increasing stigma and discrimination are among the many risk factors preventing and managing COVID-19 particularly challenging in such a setting. These include conflict-affected countries such as South Sudan, Yemen, and Syria, refugee facilities in Bangladesh and Lebanon, and internally displaced persons in Ethiopia and the Democratic Republic of Congo. The direct and indirect effects of COVID-19 and responses to control its spread in these settings are currently poorly documented and researched. The purpose of this study of ours is to review the critical literature on the role of evidence-based public health practice in mitigating the impact of the COVID-19 epidemic in humanitarian settings
