The "National Guideline for Cholera Surveillance and Outbreak Response" by the Ethiopian Public Health Institute (EPHI) provides a comprehensive approach to combating cholera outbreaks in Ethiopia. It emphasizes the importance of a multisectoral approach, including case management, WASH measures, an...d the use of cholera vaccines. A key component is the establishment of Cholera Treatment Centers (CTCs) that provide 24/7 care. Additionally, the guideline stresses water quality monitoring and hygiene practices to prevent the spread of cholera and protect public health.

Cholera epidemics continue to be a major public health problem in many countries around the
world. When epidemics strike, they can spread rapidly. The disease can also evolve quickly;
patients with severe disease can die of dehydration hours after showing the first symptoms of
cholera.
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 article "The Political Determinants of the Cholera Outbreak in Yemen" examines how the ongoing civil war has contributed to Yemen’s severe cholera outbreak. The 2017 epidemic was des...cribed as the worst in the world, with cholera spreading rapidly due to the collapse of health, water, and sanitation systems.
The analysis shows that Houthi-controlled areas were disproportionately affected, accounting for 77.7% of cases and 80.7% of deaths. The article highlights the role of the Saudi-led coalition in worsening conditions through airstrikes on infrastructure, blockades restricting medical and food supplies, and the overall humanitarian crisis. It criticizes UNICEF for accepting a $67 million donation from Saudi Arabia while the coalition contributed to the crisis.
The article underscores that political actions and conflict have been key factors in the outbreak’s severity, with both warring sides failing to protect civilians.

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 South African Department of Health reports a decline in cholera cases, with only one confirmed case out of 28 suspected cases in the last 10 days as of July 5, 2023. However, authorities urge continued vigilance, emphasizing hygiene, especially during mass gatherings.
Since February 2023, South... 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.

The Ministry of Health (MoH) of Syria officially declared a cholera outbreak on 10 September 2022, with the majority of cases reported from Aleppo, Deir-ez-Zor and Al-Hasakeh governorates. Since the situation report issued on 26 September 2022, the number of confirmed and suspected cases continues t...o rise. A total of 13 of 14 governorates are now affected, compared with 10 during the last reporting period.

The article "Effectiveness of one dose of oral cholera vaccine in response to an outbreak: a case-cohort study" investigates whether a single dose of the Shanchol oral cholera vaccine can provide effective protection during an outbreak. Conducted i...n Juba, South Sudan, in 2015, the study involved a case-cohort approach, analyzing vaccination status and disease outcomes.
Findings showed that a single dose was 80.2% effective in preventing medically attended cholera cases, increasing to 87.3% after adjustments for confounding factors. These results suggest that a single-dose strategy can be an effective emergency response, particularly in settings with limited vaccine supply and high mobility of affected populations. The study supports using a single-dose approach during outbreaks when a two-dose regimen is logistically challenging.

WHO supports Zambia in vaccinating 1 million people in Lusaka against cholera to combat an outbreak that began in October 2017, causing 2,672 cases and 63 deaths. Two million vaccine doses were provided by Gavi. WHO and the Zambia National Public Health Institute are improving water access, sanitati...on, and hygiene education while training medical staff. Another 1 million people in high-risk areas will be vaccinated later.

CORE Group has developed a module to improve preparedness for and response of communities in countries at risk of a cholera epidemic. The module consists of four lesson plans with accompanying flipcharts, intended to be delivered through community health workers. The lessons target mothers and careg...ivers of children under age five, a group that is at particular risk of death if infected. The module shares information about symptoms and risks; what families can do to prevent infection; how, when, and where to seek care; and what actions to take in the aftermath of an outbreak.

This document is a situation report (#6) from October 2, 2017, describing the cholera outbreak in Yemen. By October 1, 2017, there were 777,229 suspected cholera cases and 2,134 deaths across 22 of Yemen's 23 governorates. The response involves WASH partners providing hygiene supplies and water trea...tment, health cluster partners operating treatment centers, and communication campaigns reaching over 16 million people. Major challenges include limited supplies, security risks hindering access to affected communities, a weakened health system with over 55% of facilities closed or partially functional, and difficulties importing medicines and medical supplies. Children under 18 represent 60% of cases, while people over 60 report the highest death rates.

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.
