Cholera cases in northeastern Nigeria's Adamawa have risen to 909 since the outbreak of the water-borne disease in parts of the state, heath authorities said on Saturday.
The outbreak in Mubi North and South areas of the state has also claimed 16 lives, Fatima Atiku Abubakar, state health commissioner told reporters in Yola, the state capital.
The official said due to collaborative efforts with international partners, the fatality ratio of the outbreak has been reduced from 17 per cent to 1.8 per cent as at Friday.
Cholera is an extremely virulent disease characterised in its most severe form by sudden onset of acute watery diarrhea that can lead to death by severe dehydration, reports Xinhua.
The outbreak is common in Nigeria due to the poor water supply systems, especially in densely populated areas.
