The Nigeria Centre for Disease Control and Prevention on Thursday warned the public of the increasing trend of cholera cases across the country as the rainy season intensifies.
The NCDC, in a statement signed by its Director General, Dr Jide Idris, said from January 1st to June 11th, 2024, a total of 1,141 suspected and 65 confirmed cases of cholera with 30 deaths have been reported from 96 LGAs in 30 states.
The centre noted that the 10 states that contributed 90 to the burden of cholera include Bayelsa, Zamfara, Abia, Cross River, Bauchi, Delta, Katsina, Imo, Nasarawa, and Lagos states.
It, however, stated that a multi-sectoral National Cholera Technical Working Group, led by the centre and comprising the Federal Ministries of Environment and Water Resources, the National Primary Health Care Development Agency, the World Health Organisation, the United Nations Children’s Fund, and other partners, has been providing support to the affected states.

“This support includes risk communication, active case search, laboratory diagnosis, case management, provision of response commodities, water sanitation and hygiene interventions, and dissemination of Cholera awareness jingles in English and local languages,” it said.
Cholera is a food and water-borne disease, caused by the ingestion of the organism Vibrio cholerae in contaminated water and food. Water is usually contaminated by the faeces of infected individuals.
Contamination of drinking water can occur at the source, during transportation, or storage at home. Food may be contaminated by soiled hands, either during preparation or while eating.
“Beverages prepared with contaminated water and sold by street vendors, ice, and even commercial bottled water have been implicated as vehicles of transmission, as have cooked vegetables and fruits freshened with untreated wastewater.
“The time between infection and the appearance of symptoms is two hours to five days. It has a higher risk of transmission in areas that lack adequate sanitation facilities and a regular supply of clean water. Unsafe practices such as improper disposal of refuse and open defecation endanger the safety of water used for drinking and personal use,” NCDC highlighted.
Symptoms of cholera include acute profuse, painless watery diarrhoea (rice water stools) of sudden onset, with or without vomiting. It may be associated with nausea, profuse vomiting, and fever. Severe cases can lead to death within hours due to dehydration (massive body fluid loss). However, most infected people (about 80 per cent) may only show mild symptoms or have no symptoms at all.
