Health officials say at least 46 people have died from cholera-related symptoms in northern Nigeria over the last month.
Yobe state health chief Fatsuma Talba said Tuesday that 33 people have died in the northeastern state. Community health officer Aishatu Yahaya says 11 others died in the north-central state of Nasarawa.
And Sokoto state health chief Abdullahi Maigwandu says two children died over the weekend in the northwestern town of Gandi.
Authorities say hundreds of cholera cases have been reported since June.
Cholera is a waterborne infection that is easily preventable with clean water and sanitation.
International health officials believe an outbreak last year killed more than 1,500 people in Nigeria alone and spread to neighboring countries.
