The '100 Health Messages for Children to Learn & Share' is an educational resource developed by Children for Health. It is aimed at children aged 8–14, particularly young adolescents (aged 10–14), who often care for younger siblings. The set contains 100 simple, accurate and adaptable health mes...sages, with 10 messages on each of the following topics: Malaria, diarrhoea, nutrition, coughs and colds, intestinal worms, water and sanitation, immunisation, HIV and AIDS, accidents and injuries, and early childhood development. The messages have been reviewed by medical and education experts and are designed for use by parents, teachers and health workers in schools, homes, clinics and clubs. The resource encourages active learning through memorisation, discussion, and creative activities, empowering children to become health educators in their communities.

The article focuses on "The State of the World’s Children 2023" report published by UNICEF. It highlights the critical role of vaccines in saving lives and the challenges in global immunization efforts, especially for marginalized and underserved children. The report emphasizes the impact of COVID...-19 on routine immunization, leaving millions of children unprotected from preventable diseases. It calls for urgent measures to restore and improve vaccination coverage, ensure equity in vaccine access, strengthen primary healthcare systems, and build trust in vaccines. The report also advocates for innovations and sustainable funding to achieve immunization for every child.

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 WHO Guide on Oral Cholera Vaccines in Mass Immunization Campaigns provides guidance on the planning and implementation of oral cholera vaccine (OCV) campaigns. It covers key aspects such as when and where to use OCVs, vaccine specifications, and recommendations for use in endemic areas, outbreak... settings, and complex emergencies. The document outlines steps for macro- and micro-planning, logistics, budgeting, human resource allocation, and risk communication. It also highlights challenges, including cold chain management, vaccine supply, and community engagement, ensuring that vaccination campaigns are efficient and effective in reducing cholera outbreaks.

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.

Due to the heterogeneous distribution of malaria transmission and its determinants, subnational tailoring (SNT) provides an analytical framework to facilitate the targeting of each population with appropriate intervention packages for maximum impact to inform national strategic planning and prioriti...zation based on resources available. The WHO Global Malaria Programme recommends the use of subnational data on disease epidemiology and other relevant local contextual factors to facilitate the process of SNT. Once the strategies and intervention mixes have been defined, programmes can proceed to the prioritization of
interventions for effective programming, based on available resources

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.
