“In the last two weeks we had new and resurgence cases,” Dr. Bashir Lawan Muhammad, the state epidemiologist and deputy director of public health for northern economic hub Kano State, told Reuters.
He said the rainy season was making it worse, while insecurity in the north, where the authorities have been battling Islamist militants and armed criminals, was also hindering the authorities’ ability to respond.
Twenty-two of Nigeria’s 36 states, as well as the federal capital territory Abuja, have suspected cases of cholera, according to the Nigeria Centre for Disease Control, (NCDC).
The illness, which is caused by contaminated water, can kill within hours if not treated.
The surge has been focused in the north of the country, where health systems are least prepared.
At least 186 people had died in Kano of cholera since March, Muhammad said. The state accounts for the biggest share of the 653 cholera deaths recorded in the country as a whole by the NCDC. Nearby northern states Bauchi and Jigawa are also among the hardest hit, according to the NCDC.
Lagos-based consultancy SBM Intelligence said the states with the most fatalities showed a strong correlation with those that performed poorly in its health preparedness index published in May.
The cholera surge comes as daily COVID-19 cases hit their highest since March, raising fear of a third wave of the pandemic in Africa’s most populous nation.
