Migrants represent a highly vulnerable population due to their limited access to health information, healthcare services, and emergency response mechanisms. These vulnerabilities are exacerbated by language barriers, cultural differences, socioeconomic constraints, and the unpredictability of their living environments in host countries. The absence of knowledge and basic skills in handling injuries significantly increases their risk of complications, disability, and preventable mortality. This community-engagement program aimed to strengthen the emergency preparedness of migrants under the coordination of the International Organization for Migration (IOM) by providing culturally adapted education on injury prevention and first aid. A total of 20 migrants participated in an interactive session consisting of counseling, demonstrations, and hands-on skill practice. Knowledge acquisition was assessed using pre-test and post-test questionnaires containing ten multiple-choice items. The results revealed a 38.8% improvement in average knowledge scores (pre-test: 45.2; post-test: 74.0), with a paired t-test showing statistical significance (p = 0.0000, p < 0.05). Participants also demonstrated enthusiasm and high engagement during the practical sessions. These findings indicate that community-based, participatory education is effective for increasing first-aid competence among vulnerable migrant groups. This initiative can serve as a replicable model for migrant shelters and humanitarian organizations seeking to strengthen public health resilience.
