Evaluation of Malaria Prevention Programme Effectiveness Among Internally Displaced Persons in Adamawa State, North East Nigeria

Internally displaced persons living in humanitarian settlements in northeastern Nigeria are highly vulnerable to malaria due to the collapse of preventive infrastructure, overcrowding, limited access to health services, and disruption of regular bednet replacement and indoor residual spraying cycles. This study evaluates the effectiveness of malaria prevention programmes among internally displaced persons in Adamawa State, North East Nigeria. A cross-sectional programme evaluation was conducted at two IDP camps and three host community sites in Yola North and Yola South Local Government Areas, enrolling 400 individuals including children under five and pregnant women. Data collected included bednet coverage and use rates, uptake of intermittent preventive treatment in pregnancy, malaria confirmed case rates from camp health post records, and caregiver knowledge of preventive practices. Biomedical assessment involved rapid diagnostic testing for malaria parasitaemia in a subsample of 150 under-five children. Literature from 2020 to 2024 documents extremely high malaria case fatality rates in Nigerian IDP settings, compounded by co-epidemics of malnutrition, cholera, and acute respiratory infections. This study generates programme performance indicators against Sphere humanitarian health standards and identifies the most critical prevention gaps. Findings will be presented to UNHCR, MSF Nigeria, and the Adamawa State Emergency Management Agency.
