Cholera cases soar globally; Malawi, Haiti deadliest outbreaks, WHO reports
Health
The world enters 2024 with soaring cases of cholera globally, with over 667,000 cases and more than 4,000 deaths last year, UN agencies have reported.
Eastern and southern African nations are among the worst affected, accounting for about 75 per cent of the fatalities and a third of the cases as of 15 January, according to the UN Children’s Fund (UNICEF).
With the regions also suffering from a lack of adequate clean water and sanitation and poor case management, children are particularly vulnerable as the outbreaks spread rapidly.
“The cholera outbreak in the region is a significant concern to the health and well-being of children,” Etleva Kadilli, UNICEF director for eastern and southern Africa, said on Monday.
“Investments in strengthening systems to address the root causes of cholera and other public health emergencies, particularly on enhancing access to clean water, improved sanitation and hygiene, social behaviour change and quality of case management, are imperative,” she said.
She also highlighted the compounding impacts of climate change as well as the multifaceted consequences for children.
“Learning loss is a major concern," she explained. "It is imperative that the response not only be swift, but also considers the long-term wellbeing of these young children. As the new school year is starting in many countries in the region, it is crucial for measures to be put in place in schools to protect children against infections.”
‘Grade 3 Emergency’
Meanwhile, the World Health Organization (WHO) reported that preliminary data from UN Member States indicate that the number of cholera cases reported in 2023 as of 15 December surpassed that of 2022.
“Nearly a year has passed since WHO classified the global resurgence of cholera as a grade 3 emergency, the highest internal level for a health emergency requiring a comprehensive response,” the agency said in a report issued last week.
WHO is currently reviewing its response to cholera globally to identify key lessons and make evidence-based adjustments where needed to better coordinate activities in the coming months.
“Based on the large number of outbreaks and their geographic expansion alongside the shortage of vaccines and other resources, WHO continues to assess the risk at the global level as very high,” the agency added.
It also noted that the figures must be “interpreted with caution”, given varying surveillance systems and capacity across countries, meaning that 2023 data are not directly comparable to reports from previous years.

Deadliest outbreaks
The outbreaks were the deadliest in Malawi, in southern Africa, and Haiti, in the Caribbean.
As of mid-December, 1,771 people lost their lives to the disease in Malawi, while 1,156 succumbed in Haiti.
Elsewhere in Africa, the Democratic Republic of the Congo (DRC) is reporting close to 1,000 cases each week, while Mozambique and Zimbabwe are experiencing a rise in cases and a spread of outbreaks. Burundi and Zambia also continue to report active outbreaks, according to the report.
Afghanistan reported the highest numbers of suspected and/or confirmed cases, although the country uses a different surveillance system from other nations.
