This article describes WHO's efforts to combat a cholera outbreak in South Sudan in July 2017. The organization received 500,000 doses of oral cholera vaccine (OCV) and was working with South Sudan's Ministry of Health to launch a vaccination campaign from July 28 to August 3, 2017. At the time, the
...
country had reported 17,785 cholera cases and 320 deaths since the outbreak began in June 2016. The vaccination campaign targeted four counties with high transmission rates: Tonj East, Kapoeta South, Kapoeta North, and Kapoeta East. South Sudan was implementing an integrated approach to control cholera, combining patient care, surveillance, social mobilization, water and sanitation improvements, and vaccination. The article notes that approximately 6 million people in South Sudan were facing starvation, with food insecurity and drought exacerbating the risk of cholera spread as people resorted to using contaminated water sources.

se of use by non-laboratory personnel, and their role in early outbreak identification and surveillance. However, it emphasizes that RDTs should not replace culture or PCR testing, as they vary in sensitivity (58-100%) and specificity (60-100%). The document advises on proper test selection, storage, training, and integration into national surveillance systems to enhance cholera response efforts.

The document outlines the 2017 cholera outbreak in Zambia, mainly in Lusaka, due to poor sanitation and unsafe water. By December, 493 cases were reported, with risks increasing due to the rainy season. The Zambia Red Cross Society (ZRCS), in collaboration with the Ministry of Health, WHO, and UNICE

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.

sease prevention through successful water, sanitation, hygiene and vaccination campaigns and coverage. However, given the limited evidence that exists with respect to the occurrence of resistant organisms in the nation, it is hard to estimate the exact antimicrobial resistance (AMR) scenario. Also, it becomes difficult to compare the current situation with other countries in the region. Moreover, limited evidence exists on the trends of use of antimicrobial agents (AMA) in Maldives. Although, recent prescription audits have indicated overuse of antibiotics, especially for common conditions such as flu, cough and fever.

This neglect is, in part, a consequence of under-reporting, resulting in an underestimation of their global burden that downgrades their relevance to policy-makers and funding agencies. Increasing awareness about the causes of NZDs and how they can be prevented could reduce the incidence of many endemic zoonoses.

ance & Reporting, Use of Oral Cholera Vaccines (OCV), Healthcare System Strengthening, and Community Engagement.
Ethiopia has historically faced recurrent cholera outbreaks due to poor sanitation, unsafe water, and weak health infrastructure. The plan prioritizes high-risk areas (hotspot woredas) and aims to reduce cholera-related mortality by 90% by 2028. It includes efforts to improve WASH conditions, strengthen disease surveillance, enhance rapid response capabilities, expand vaccination campaigns, and integrate cholera control into broader health policies.
The government, in collaboration with international partners such as WHO, UNICEF, and the Global Task Force for Cholera Control (GTFCC), will implement and monitor the plan. The estimated budget for the initiative is $390 million over eight years. Ethiopia aims to achieve zero cholera transmission in hotspot regions, ensuring sustainable public health improvements.

Africa has recorded 1,073 suspected cholera cases, with 198 confirmed cases across five provinces. Gauteng Province is the most affected, with 176 cases, primarily in Hammanskraal, Tshwane. Other affected provinces include Free State, North West, Limpopo, and Mpumalanga.
The outbreak has resulted in 47 deaths, with four new suspected deaths reported in the Free State. The majority of confirmed cases are in individuals aged 41-50 years, and 52% of cases are female.
The health department continues preventive efforts through health education and targeted case-finding. Authorities also stress the importance of clean water and hygiene compliance in initiation schools to prevent further outbreaks.
