The Biafra government prioritized diversity, and collaboration in its public health policy initiative to meet the health needs of its population during the Biafra war. The policy helped to ensure that internal and external professionals delivered the health needs of civilians during the war. However, continuous blockage of food, firearms, and medical supply links to Biafra by the Nigerian government led to eventual starvation, malnutrition, and disease outbreak among Biafrans during the war. Besides, the diversity and collaboration health policy by the Biafra government boosted the effectiveness of operational staff because they worked closely with those from other nations to improve the health and wellbeing of the Biafrans. The study was conducted by carrying out a literature review on different historical and up to date sources such as archived data, journals, articles, books, and newspapers. The researcher recommended that the policies and interventions of the government, public health organizations and other humanitarian bodies helping in the warfare should be shaped toward improving the health and wellbeing of people affected by war.
