Although tremendous progress has been made toward reducing the global burden of malaria, this disease remains a significant public health challenge in sub-Saharan Africa. In Ethiopia, confirmed malaria cases tripled between 2019 and 2023 and have continued to rise. Malaria surveillance is a core intervention that can improve targeting and increase the effectiveness of malaria control and elimination efforts. However, accomplishing this goal will require shifting from reactive to predictive approaches that leverage surveillance data to understand variation in malaria transmission over space and time. In this seminar, I will present the results of collaborative research in Ethiopia on the influences of climate and land cover on malaria epidemics. The aims are to elucidate the environmental determinants of malaria and develop predictive models for disease forecasting and risk mapping. The results of this research have been incorporated into the Epidemic Prognosis Incorporating Disease and Environmental Monitoring for Integrated Assessment (EPIDEMIA) system, a set of software tools designed to automate data processing, modeling, and report generation for malaria early warning.

Each year, the WHO World Malaria Report provides a comprehensive and up-to-date assessment of trends in malaria control and elimination worldwide. The 2025 edition reviews investments in malaria programs and research and assesses progress in all key areas of intervention—prevention, diagnosis, treatment, elimination, and surveillance—in 80 countries where malaria is endemic. This year's report highlights the growing threat of antimalarial drug resistance. Since 2000, 2.3 billion malaria cases and 14 million deaths have been prevented worldwide—including 1 million lives saved in 2024 alone—and progress toward global elimination goals has continued, with 47 countries and one territory now officially certified malaria-free by the WHO. Despite this progress, malaria remains a significant global health problem, with approximately 282 million cases and 610,000 deaths in 2024, about 9 million more cases than the previous year. The WHO African Region continues to bear the brunt of the burden, with 11 countries accounting for about two-thirds of global cases and deaths. However, progress in reducing malaria mortality rates remains very insufficient.

This study analyzes the "verticality trap" in Northern Nigeria, where fragmented logistics systems contribute to persistent malaria treatment gaps. Using a retrospective analysis of DHIS2 data (2022–2024) across Kebbi, Sokoto, and Zamfara, the research evaluates the structural misalignment between routine case management (ACTs) and Seasonal Malaria Chemoprevention (SMC) campaigns. The Key Findings are 1) Treatment Deficits 2) System Saturation 3) Data Incongruity. The Presentation proposes an Integrated Logistics Framework designed to harmonize quantification and distribution schedules. By transitioning from parallel to integrated systems, Nigeria can reduce stock outs, improve data quality, and safeguard equitable access to life-saving commodities.

This webinar was presented in French. Impact of RR, RS, and kdr genotype transmission on the prevalence of microsporidian infection in An. gambiae s.s. and An. coluzzii in southern Benin. Research in entomology and vector genetics plays a key role in understanding malaria transmission and guiding control strategies. For our January 2026 session, the presentation highlighted the effect of genotypes associated with the kdr mutation on Microsporidia MB infection and their potential implications for malaria control.
