The technical note from the Global Task Force on Cholera Control (GTFCC) examines the risks and benefits of vaccinating pregnant women with WHO-prequalified oral cholera vaccines (OCVs) during mass vaccination campaigns. It highlights that three WHO-approved vaccines (Dukoral®, Shanchol™, and Euv...ichol®) offer sustained protection and a strong safety profile.
While these vaccines are not explicitly contraindicated for pregnant women, there is limited clinical data on their use during pregnancy. However, studies indicate that pregnant women with cholera face higher risks of fetal loss, stillbirth, and complications, especially if they experience severe dehydration. Some evidence suggests that vaccination can reduce cholera incidence in pregnant women and indirectly protect infants.
Although no controlled trials have focused on pregnant women, retrospective studies in Guinea and Zanzibar showed no significant increase in adverse pregnancy outcomes after OCV administration. The GTFCC concludes that the benefits of vaccination outweigh the risks, particularly in high-risk areas, and recommends including pregnant women in cholera vaccination campaigns while continuing to monitor safety data.

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.

La vidéo "Choléra - Questions & Réponses" de l'Organisation Mondiale de la Santé (OMS) explique les aspects essentiels du choléra, une maladie diarrhéique aiguë causée par l'ingestion d'eau ou d'aliments contaminés par la bactérie Vibrio cholerae. Elle met en avant les principaux symptôme...s, notamment une diarrhée aqueuse sévère, des vomissements et une déshydratation rapide, pouvant être mortelle sans traitement adéquat. La transmission se fait principalement par l’eau insalubre et les mauvaises conditions sanitaires. Pour prévenir la maladie, il est essentiel d'avoir accès à de l'eau potable, d'améliorer l'hygiène et l'assainissement, et d'utiliser la vaccination dans les zones à haut risque. En cas d'infection, la réhydratation orale ou intraveineuse est le traitement principal, tandis que les antibiotiques sont parfois administrés dans les cas graves. La vidéo insiste sur l'importance d'une intervention rapide et de mesures préventives pour limiter la propagation du choléra et protéger les populations à risque.

The video "Cholera - Questions & Answers" by the World Health Organization (WHO) explains the essential aspects of cholera, an acute diarrheal disease caused by ingesting water or food contaminated with the Vibrio cholerae bacterium. It highlights the main symptoms, including severe watery diarrhea,... vomiting, and rapid dehydration, which can be fatal without proper treatment. Transmission occurs primarily through unsafe water and poor sanitation conditions. To prevent the disease, it is crucial to have access to clean drinking water, improve hygiene and sanitation, and use vaccination in high-risk areas. In case of infection, oral or intravenous rehydration is the primary treatment, while antibiotics are sometimes administered in severe cases. The video emphasizes the importance of rapid intervention and preventive measures to limit the spread of cholera and protect at-risk populations.

Individuals in areas with unsafe drinking water, poor sanitation, and inadequate hygiene are at the highest risk. The page emphasizes the importance of early and proper treatment, such as rehydration therapy, to improve survival rates. Preventative measures include using treated water, practicing good hygiene, and vaccination, especially for travelers to regions where cholera is prevalent.

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.

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 Cholera Q&A Fact Sheet provides essential information about cholera, including its causes, symptoms, treatment, and prevention. Cholera is an acute diarrheal disease caused by Vibrio cholerae, which spreads through contaminated water and food. It leads to rapid dehydration and can be fatal if un...treated. Symptoms range from mild diarrhea to severe dehydration, shock, and death.
Treatment primarily involves Oral Rehydration Therapy (ORT) to replace lost fluids, and in severe cases, intravenous fluids. Antibiotics are generally not recommended for mass treatment. Prevention focuses on safe drinking water, sanitation, hand hygiene, and proper food handling.
The document also discusses cholera vaccination, with three WHO-approved oral vaccines available. However, vaccines should be used alongside other control measures. The Global Task Force on Cholera Control (GTFCC) aims to eliminate cholera transmission in 20 countries by 2030 through improved sanitation, vaccination, and rapid outbreak response.

The Epidemic Preparedness and Response Plan for Cholera in Syria (November 2015) outlines strategies to prevent, detect, and manage cholera outbreaks in the country, where poor water and sanitation conditions, displacement, and damaged healthcare infrastructure increase the risk of disease spread. T...he plan aims to reduce morbidity and mortality through early detection, rapid response, and coordinated interventions. It is divided into four key phases: the Pre-Epidemic Phase, which includes risk assessment, resource mapping, stockpiling medical supplies, training health workers, and raising community awareness; the Alert Phase, which focuses on surveillance, laboratory confirmation, and mobilization of rapid response teams; the Epidemic Phase, which involves case management, infection control, environmental measures such as water chlorination and improved sanitation, and public awareness campaigns; and the Post-Epidemic Phase, which evaluates the response effectiveness and identifies lessons to improve future preparedness. The plan emphasizes multi-sectoral coordination, strengthening health surveillance, and ensuring timely intervention to control and prevent cholera outbreaks in vulnerable communities.
