The European Union has allocated €1.5 million to Nigeria as part of a wider emergency package aimed at containing cholera outbreaks across several African countries.
The total intervention is worth €2.3 million.
Nigeria will receive the largest allocation, while Cameroon, the Central African Republic and Chad will receive smaller amounts.
The funding will support additional outbreak response teams, cholera treatment supplies, water and sanitation measures, surveillance and public awareness campaigns.
The World Health Organisation reported 61,888 cholera cases and 1,230 deaths across 16 African countries between January and the end of May 2026.
Nigeria recorded 6,860 cases and 80 deaths during the period.
WHO figures showed a sharp increase in Nigerian cases in May, with 5,798 infections and 54 deaths reported during the month.
The EU said the Nigerian allocation would support treatment of public water points and household water, improved case management and stronger surveillance in hard to reach communities.
Community sensitisation will also be expanded to improve understanding of transmission and prevention.
Cameroon is expected to receive €100,000 for containment activities and additional treatment capacity.
The Central African Republic will receive €500,000 for vaccination, case management, water and sanitation interventions and surveillance.
Chad will receive €200,000 for measures aimed at interrupting transmission and strengthening community level response.
EU Commissioner Hadja Lahbib said cholera remained preventable and treatable but continued to kill people where access to safe water and healthcare was inadequate.
WHO has identified conflict, displacement, climate related events, weak infrastructure and poor access to healthcare as major factors complicating control efforts.
The European Union and WHO had earlier launched a separate programme aimed at improving disease surveillance and outbreak detection in Nigeria.
The latest funding is intended to strengthen immediate response while longer term improvements in water, sanitation and public health infrastructure remain necessary.
