Thirty persons died in Jigawa and over 2,000 hospitalised in the past two months.
In Enugu, 14 persons died of the disease.
Dr Salisu Mu’azu, Permanent Secretary, Jigawa State Ministry of Heath, who confirmed the outbreak, said most of the infected cases were children in nine local government areas.
Mu’azu listed Hadejia; Dutse, Kirikasamma, Birnin Kudu and Ringim as some of the areas worst hit by the outbreak.
He said that of the 2,000 infected cases, some have been discharged while others were still receiving free medical treatment in government hospitals.
The permanent secretary did not have information on the cause of the outbreak in many of the affected areas but he said the Hadejia case could be linked to water pollution.
Mu’azu said the state government was on top of situation, and has been providing assistance to residents in the affected areas.
Ikechukwu Obi, Enugu commissioner of health, in a statement on Friday, said seven people died of the disease around New Artisan market in the state.
Boniface Okoro, director of public health and disease control, ministry of health, on Monday, clarified the situation, saying there were seven more deaths on Monday, added to the previous seven on Saturday, with 19 persons identified with symptoms.
“Seven persons died initially on Saturday, but as of Monday, seven more deaths were confirmed, raising the fatality to 14,” he said.
He said many of the patients were taken to Enugu State University Teaching Hospital, while others were taken to a private hospital in the city.
He said upon receiving reports of the deaths, the ministry’s rapid response team carried out an immediate investigation and “it was observed that the patients presented with sudden onset of passage of loose stool and vomiting”.
Okoro said the state government has launched an aggressive sensitisation campaign for residents to take precautionary steps towards preventing further spread.
He also said some patients have recovered and have been discharged from hospital, but added that a fresh case of the infection was reported on Monday morning, indicating the possibility of a further spread if residents do not take precautions.
The cholera outbreak has been confirmed in several states, including the federal capital territory (FCT), Benue, Delta, Zamfara, Bauchi, Kano, Niger, Kaduna, Plateau, Nasarawa, Gombe, Bayelsa and Kebbi.
