Cholera cases are decreasing worldwide, but in Africa both endemic occurrences (continual cases) and periodic epidemics persist. Sub-Saharan Africa bears the biggest cholera burden (Ali et al. 2015) and also has the highest mortality rate per case (WHO 2019c). The oral cholera vaccine (OCV) can be used to prevent outbreaks during crisis situations as it provides protection for approximately three years. However, long-term control involves a combination of vaccination and WASH (WHO 2019c). Focusing targeted interventions in countries with the highest incidences (Democratic Republic of the Congo, Ghana, Nigeria, Somalia and Sierra Leone) could reduce cases by almost 40 per cent across the region (Lessler et al. 2018).
