Cholera in Africa: A Climate Change Crisis.
Review in Journal of epidemiology and global health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCholera, an acute diarrheal infection caused by Vibrio cholerae, remains a significant public health concern globally, with 1.4-4.0 million cases and 21,000-143,000 deaths annually. While the disease is endemic in 47 less-developed countries across Africa and Asia, the African continent has been particularly affected, with 19 of 29 countries reporting cases in 2023 being from Africa.
aimTo explore the trend of cholera outbreaks in Africa and analyze how climate change has contributed to the spread of the disease in the continent.
methodsA review of current cholera outbreaks in Africa, with particular focus on Sudan and Ethiopia as case studies, examining the relationship between climatic factors and cholera transmission.
resultsRecent outbreaks in Sudan (declared September 26, 2023) resulted in 5,414 suspected cases and 170 deaths (case fatality rate 3.1%) across nine states as of December 5, 2023. In Ethiopia's Somali region, 772 confirmed cases and 23 deaths were reported within two weeks, with approximately 80% of cases affecting children. Climate factors significantly influence cholera transmission: a 1 °C temperature rise doubled cholera cases in Zanzibar. Both drought conditions, which increase Vibrio cholerae concentration in groundwater, and heavy rainfall periods, which lead to flooding and breakdown of sanitary conditions, contribute to outbreak risks.
conclusionsClimate change impacts cholera transmission through rainfall patterns, temperature variations, and extreme weather events. Management recommendations include implementing accurate weather surveillance systems, strategic vaccination programs, flood-proof water supply infrastructure, and community engagement protocols. These interventions should be integrated while considering the growing influence of climate change on disease patterns. CLINICAL TRIAL NUMBER: Not applicable.
