"Six people died out of the 46 cases recorded," Abubakar Labaran Yusuf told AFP of the outbreak this week in Kafin Dalawa village yesterday, 70 kilometres (43 miles) outside the state capital of Kano.
Contaminated water in the area was the most likely cause, he said, adding that teams had been dispatched to clean water sources and supply drugs.
But a local medical charity put the toll higher, saying at least 16 people had died and the outbreak was threatening to become a pandemic.
He said the organisation had been treating patients in a make-shift hospital in the village since the outbreak.

"The outbreak is becoming a pandemic in the area because patients are trooping from neighbouring villages, which is putting a strain on our team and medical supplies," Alkassim said.
Cholera, a highly contagious intestinal infection, is transmitted by water soiled by human waste. The disease leads to diarrhoea, dehydration and death if untreated.
