1,141 Cholera Cases Reported In 30 States – NCDC

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 agency, in a statement signed by its Director-General, Dr Jide Idris, said from January 1 to June 11, 2024, a total of 1,141 suspected and 65 confirmed cases of cholera with 30 deaths had been reported from 96 local government areas in 30 states.

The NCDC listed the 10 states that contributed 90 per cent to the burden of cholera as Bayelsa, Zamfara, Abia, Cross River, Bauchi, Delta, Katsina, Imo, Nasarawa, and Lagos.

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, had 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 and the 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,” the statement stated.

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.

The agency noted that people most at risk of cholera are those of all ages living in places with limited access to clean water, people living in areas with poor sanitation and poor hygiene, people living in slum areas where basic water or sanitation infrastructure is missing, people living in rural areas who depend on surface water or unsafe piped or borehole well water sources for drinking, and people who consume potentially contaminated food or fruits without washing and cooking properly.

Others at risk are those who do not perform hand hygiene at appropriate times, those affected by man-made or natural disasters like floods, resulting in population movements and overcrowded refugee camps, relatives who care for sick people with cholera at home, healthcare workers, including doctors, nurses, and other health workers who provide direct patient care in the absence of standard precautions.

The NCDC said the disease could be easily treatable if detected early, as most infected people could be treated successfully through prompt administration of oral rehydration solution to replace lost fluids and electrolytes, and appropriate antibiotics.
