The cholera epidemic is spreading rapidly in northeastern Nigeria, where the Boko Haram jihadist movement is fighting, which resulted in the death of more than 175 people and injuring of 10,000 others, reports Reuters.
"The disease is spreading rapidly in IDP camps, which have limited access to adequate sanitation," Janet Cherono, head of the Norwegian Refugee Council project in Maiduguri, said. "The rainy season has exacerbated these conditions."
Since the beginning of November, 175 deaths and 10,000 deaths have been reported in the three states in the northeast of the country (Borno, Adamawa and Yobe).
The organisation is particularly concerned about the "very high population density" in IDP camps or informal camps where people have sought refuge from fighting between the Nigerian army and Boko Haram rebels.
Maiduguri, the largest city in northeastern Nigeria, received 243,000 displaced people, according to the International Organisation for Migration (IOM).
"For example, in the camps of the displaced in Cajuni Sanghaya, eight baths were built for about 150 people, and today 500 people live in the camp," Janet Cherono said.
Nigerian President Mohamed Bukhari, who is campaigning for re-election in February, declared a "health emergency" during a summit on access to water.
Cholera is an inflammation that leads to severe diarrhea transmitted through contaminated food or contaminated water. It is easily treated by fluid recovery but can lead to death within hours unless it is treated.
Boko Haram's insurgency and the army campaign against it have killed more than 34,000 people since 2009, and around 1.8 million people are still unable to return to their homes, while 11 million Nigerians are in desperate need of humanitarian aid, according to non-governmental organisations.
