UNICEF reports that the Democratic Republic of the Congo (DRC) is experiencing its most severe cholera outbreak in six years, with over 31,000 suspected or confirmed cases and 230 deaths in the first seven months of 2023. The North Kivu province is particularly affected, recording more than 21,400 c...ases, including over 8,000 children under five—a sixfold increase compared to all of 2022. The surge is attributed to escalating conflict and displacement in eastern DRC, leading to overcrowded camps with inadequate water and sanitation facilities, creating conditions conducive to cholera transmission. UNICEF emphasizes the urgent need for improved access to clean water, sanitation, and healthcare to prevent further spread of the disease.

The study on single-dose cholera vaccine in Zambia evaluates the effectiveness of using a single dose of the oral cholera vaccine (OCV) during a 2016 outbreak in Lusaka. Due to limited vaccine supply, authorities opted for a one-dose emergency campaign instead of the usual two-dose regimen. A matche...d case-control study was conducted to assess vaccine effectiveness, showing 88.9% short-term protection against cholera. The findings suggest that a single-dose approach can be an effective strategy in outbreak settings, especially when vaccine supplies are constrained. However, further research is needed to determine long-term immunity and effectiveness in young children.

The technical note by the Global Task Force on Cholera Control (GTFCC) discusses the use of Oral Cholera Vaccines (OCVs) for international workers and travelers in cholera-affected areas. It reviews the effectiveness of WHO-prequalified vaccines (Dukoral®, Shanchol™, and Euvichol®), emphasizing ...their role in preventing infection and reducing transmission risks.
The document highlights concerns about travelers contracting cholera in endemic regions and potentially spreading the disease upon returning home. While the overall risk is considered low, certain groups, such as humanitarian workers and travelers to high-risk areas like South Asia, face a higher exposure.
Recommendations include vaccination for emergency and relief workers who may come into direct contact with cholera patients or contaminated environments. However, routine vaccination for general travelers is not widely recommended. The note also calls for better surveillance and studies to assess the potential of vaccines in preventing international transmission.
