GPH 76: Malaria

Malaria remains one of the most significant parasitic diseases worldwide, with a disproportionate burden in sub-Saharan Africa. Transmitted by the Anopheles mosquito, malaria reflects the complex interplay between environment, vector ecology, socioeconomic conditions, and health system capacity.This episode explores:• Global epidemiology and regional distribution• The life cycle of Plasmodium species• Transmission dynamics and seasonality• High-risk populations - children under five and pregnant women• Insecticide-treated bed nets and indoor residual spraying• Artemisinin-based combination therapy• Drug and insecticide resistance• Climate change and vector expansion• Global eradication initiatives and surveillanceMalaria illustrates how disease control depends not only on treatment but on vector management, housing conditions, and sustained prevention strategies. Gains achieved over recent decades through bed net distribution, rapid diagnostic testing, and effective therapies have reduced mortality substantially - yet elimination remains uneven.Environmental change, urbanisation, and resistance threaten progress, underscoring the need for continued investment and innovation.Malaria control is both ecological and political - shaped by geography, governance, and sustained commitment.────────────────────────────Key Takeaways• Malaria remains a major cause of morbidity and mortality in endemic regions• Transmission depends on vector ecology and environmental conditions• Bed nets and indoor spraying significantly reduce risk• Drug and insecticide resistance threaten progress• Climate change may expand transmission zones• Children and pregnant women are particularly vulnerable• Sustained global coordination is required for elimination This is a public episode.
