ABUJA: A cholera outbreak in Bukkuyum district of Zamfara state, northwest Nigeria, has claimed at least eight lives and infected over 200 people across 11 communities, residents and local officials said on Thursday, as limited health care access and insecurity exacerbate the crisis. Cholera, a water-borne disease, is not uncommon in Nigeria where health officials cite widespread shortages of clean water in rural areas and urban slums.
