The Ethiopia Cholera Outbreak - Flash Update #8 reports a worsening cholera crisis, with 11,407 cases and 156 deaths as of June 20, 2023. The outbreak, ongoing since August 2022, has spread across 79 districts in Oromia, Somali, SNNP, and Sidama regions, increasing by 85% since May.
Key challenges ...include contaminated water, insecurity, floods, and a global vaccine shortage, leaving 7.7 million people at risk. Only 15% of affected areas have contained the disease. A vaccination campaign has reached 1.9 million people, and 81 Cholera Treatment Centers (CTCs) have been set up, but funding remains critically low.
The United Nations (OCHA) warns that the upcoming rainy season may worsen the outbreak, requiring urgent intervention.

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.

Protection from a Single Dose of HPV Vaccine A major public health impact from IARC studies of vaccine efficacy.
The WHO Cholera Vaccine Position Paper (August 2017) highlights the importance of oral cholera vaccines (OCVs) as a key tool in outbreak response and prevention, alongside water, sanitation, and hygiene (WASH) measures. It recommends OCVs for high-risk populations, endemic areas, and humanitarian cr...ises, emphasizing their effectiveness in reducing cases and mortality. The paper discusses two types of OCVs (Dukoral®, Shanchol™, Euvichol®) and supports the WHO-managed vaccine stockpile for rapid deployment in cholera-prone regions.

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.

The document presents Cameroon's National Response Plan for the 2018 cholera outbreak, covering August to October 2018. It highlights the epidemiological situation, with outbreaks reported in the North and Central regions and a total of 109 suspected cases and 9 deaths by July 2018. The plan outline...s strategies for controlling the epidemic, including epidemiological surveillance, improved access to clean water, sanitation, mass vaccination, community awareness campaigns, and hospital and community-based treatment.
The response is coordinated by the Ministry of Public Health, WHO, and various partners, focusing on early detection, rapid response, and multi-sectoral collaboration. Challenges include poor sanitation, limited healthcare infrastructure, and cross-border disease transmission risks. The plan emphasizes resource mobilization, monitoring, and evaluation to contain the outbreak and prevent future cases.

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 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.
