A total of 922 cholera cases have been recorded in Nigeria so far, with 32 deaths reported in 2023, according to the latest situation report from the World Health Organization (WHO). As of 5 March 2023, the case‑fatality rate (CFR) stands at 3.5 percent. The WHO notes that these figures include both suspected cases identified by rapid diagnostic tests and laboratory‑confirmed infections, but cautions that the numbers are unreliable because of variations in reporting systems and under‑reporting.
Cholera is an acute diarrheal illness caused by infection of the intestine with *Vibrio cholerae* bacteria, typically contracted by ingesting contaminated food or water. While many infections are mild or asymptomatic, severe cases can be life‑threatening. As of 20 March 2023, at least 24 countries continue to report cholera cases. Historical transmission patterns and seasonality indicate that many regions are currently in low or inter‑epidemic periods, suggesting that case numbers could rise in the coming months. Mortality remains a particular concern, as several countries have reported higher CFRs than in previous years.
A separate situation report from the Nigeria Centre for Disease Control (NCDC) shows that, between October 2022 and 5 March 2023, there were 157 confirmed meningitis cases and 628 suspected cases, including 52 deaths, across 21 states and 66 local government areas (LGAs). The overall CFR for meningitis is 8.3 percent. Meningitis is an inflammation of the meninges—the protective membranes covering the brain and spinal cord—characterized by fever, headache, nausea, vomiting, neck stiffness, and altered consciousness. The most affected age group was 5–14 years, with males accounting for 62 percent of cases and females 38 percent. Ninety‑one percent of cumulative cases originated from four states: Jigawa (509 cases), Bauchi (23), Zamfara (22) and Oyo (14). Ten LGAs in five states (Jigawa 7, Bauchi 1, Oyo 1, Plateau 1, Zamfara 1) reported more than five cases each during the 2022/2023 CSM season.
Obinna Chukwudi, a medical laboratory scientist in the Department of Microbiology at Nnamdi Azikiwe University Teaching Hospital, expressed concern over Nigeria’s preparedness for disease outbreaks. He warned that recent cholera and meningitis outbreaks highlight weaknesses in containment strategies for future, more dangerous emergencies. Chukwudi emphasized that socioeconomic factors increase vulnerability to infection and urged the government, guided by health experts, to strengthen policies that improve public health. He advocated a multifaceted approach—including public policy, surveillance, water purification, hygiene promotion, community sensitization, and vaccination—to prevent, control, and reduce the burden of cholera and meningitis in affected states.
Similarly, Ondo State Epidemiologist Dr Stephen Fagbemi called for joint efforts between government and citizens to combat diseases. He stressed the need for increased public awareness and urged people to seek medical care promptly when symptoms appear.
