The persistent challenge of cholera in Africa: a complex interplay of factors

Abstract

Cholera remains a formidable public health challenge across Africa, disproportionately impacting marginalized and vulnerable populations [1]. The disease's persistence underscores its multifaceted nature, rooted in more than just the biological characteristics of Vibrio cholerae. Instead, it reflects a complex interplay of environmental, social, economic, and systemic factors, each compounding the difficulty of effective prevention and control [1,2]. Africa continues to bear the highest burden of cholera globally, with recurring outbreaks that cause significant morbidity and mortality, often overwhelming already fragile healthcare systems [3]. The disease frequently strikes regions plagued by inadequate access to clean water, sanitation, and hygiene (WASH) infrastructure [3,4]. These deficiencies create fertile ground for the bacterium's proliferation, particularly in densely populated urban slums and rural areas with limited public health outreach. Climate change further exacerbates the problem, with extreme weather events such as floods and droughts creating conditions conducive to cholera outbreaks [5].
