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.

Neonatal tetanus (NT), a severe newborn illness from the toxigenic strains of Clostridium tetani, persists in middle- and low-income countries due to non-sterile childbirth practices. Unlike smallpox and polio, tetanus cannot be eradicated: Clostridium tetani spores exist in the environment, and ani...mal reservoirs. However, elimination as a public health issue is achievable through widespread tetanus vaccination, clean deliveries, and proper umbilical cord care. The goal of eliminating maternal and neonatal tetanus (MNT) as a public health problem is considered met when all municipalities in a country have an annual incidence rate of NT of less than 1 case per 1000 live births. The Region of the Americas achieved the maternal and neonatal tetanus elimination (MNTE) target in 2017 when elimination was validated in the Republic of Haiti. Yet maintaining this progress requires continued efforts. High vaccination coverage, booster doses in countries lacking them, hygienic practices, and strong maternal and child health services are key. The Pan American Health Organization’s (PAHO) integrated maternal and neonatal immunization platform further strengthens this fight against early childhood diseases.

Cervical cancer is the second most common cancer among women worldwide and causes a significant number of deaths in the South-East Asia Region. Nearly 200 000 new cases of cervical cancer occurred in SEA Region Member States in 2008, giving an incidence of almost 25 per 100... 000 and a mortality rate of almost 14 per 100 000. Cervical cancer can be prevented by early screening and vaccination. However, due to poor access to screening and treatment services, the vast majority of these deaths occur in women from nine Member States of the South-East Asia Region which account for more than one third of the global burden of cervical cancer.

This module is part of the WHO series The Immunological Basis for Immunization, which was initially developed in 1993 as a set of eight modules, comprising one module on general immunology and seven modules each devoted to one of the vaccines recommended for the Expanded Programme on Immunization, i....e. vaccines against diphtheria, measles, pertussis, polio, tetanus, tuberculosis and yellow fever. Since then, this series has been updated and extended to include other vaccines of international importance. The main purpose of the modules is to provide national immunization managers and vaccination professionals with an overview of the scientific basis of vaccination against a range of important infectious diseases. The modules developed since 1993 continue to be vaccine-specific, reflecting the biological differences in immune responses to the individual pathogens and the differing strategies employed to create the best possible level of protection that can be provided by vaccination. The modules also serve as a record of the immunological basis for the WHO recommendations on vaccine use, published in the WHO vaccine position papers.*

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

L’orthopoxvirus simien ou virus de la variole du singe (MPXV), est un virus à ADN double brin qui appartient au genre Orthopoxvirus de la famille
des Poxviridés. Les poxvirus causent des maladies chez l’espèce humaine et beaucoup d’autres animaux ; l’infection se manifeste généralement... par la formation de lésions, de nodules cutanés ou d’une éruption cutanée disséminée. Les autres espèces d’orthopoxvirus (OPXV) pathogènes pour l’être humain comprennent le virus de la variole bovine et le virus variolique (responsable de la variole, qui a été éradiquée). Le virus de la vaccine est également un OPXV qui a été utilisé pour la vaccination humaine, et a été un outil essentiel pour l’éradication de la variole, obtenue en 1980. Le MPXV doit son nom au fait qu’il a été identifié pour la première fois chez le singe. Le MPXV se retrouve principalement chez les rongeurs, mais son réservoir reste indéterminé. Il existe deux clades connus du MPXV, l’un endémique en Afrique de l’Ouest, et l’autre dans la région du bassin du Congo.

Main Points
The delivery of humanitarian assistance is expected to slow down significantly over the next seven to ten days in anticipation of the electoral process and limited availability of transport and security assets.
The percentage of extremely food-insecure people who have recei...ved food assistance increased to 65 per cent, as 520,000 people of the targeted 806,000 have now been reached.
Health partners have expressed concern over growing evidence of a spike in cases of severe acute malnutrition in hard-to-reach areas in the Sud region.
Cholera response partners are optimistic that the vaccination campaign of 8 to 15 November will contribute to reducing transmission in Sud and rand’Anse and the risk of a future outbreak

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines.
Updated risk rates for hospital admission in patients with non-severe COVID-19
The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19.
The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients.
This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines:
**High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%.
**Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%.
Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk.
Review of COVID-19 treatments for people with non-severe COVID-19
WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022.
If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead.
WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission.
For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol.
WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials.
The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials.

COVID-19 vaccine hesitancy is currently one of the main obstacles to worldwide herd immunity and socioeconomic recovery. Because vaccine coverage can vary between and within countries, it is important
to identify sources of variation so that policies can be tailored to different population groups. ...In this paper, we analyze the results from a survey designed and implemented in order to identify early adopters and
laggers in six big cities of Latin America. We find that trust in government and science, accurate knowledge about the value of vaccination and vaccine effects, perceived risk of getting sick, and being a student
increase the odds to get vaccinated. We also identify potential laggers as women and populations between 20 and 35 years old who are not students. We discuss specific strategies to promote vaccination among
these populations groups as well as more general strategies designed to gain trust. These findings are specific to the context of Latin America insofar as the underlying factors associated with the choice to be
vaccinated vary significantly by location and in relation to individual-level factors.

The PDF "COLERA: Informação para Promotores de Saúde" provides essential guidance for health promoters and activists on cholera. It explains that cholera is characterized by severe watery diarrhea, often resembling rice water, and sometimes vomiting. If not treated promptly, it can lead to death ...within hours. The disease affects both adults and children and spreads through contaminated feces, poor hygiene, and unsafe water or food. To prevent cholera, the document emphasizes the importance of drinking treated or safe water, cooking food thoroughly and keeping it covered, washing hands with soap or ash after using the latrine and before handling food, and using proper latrines or sanitary facilities. It also highlights the role of vaccination, recommending the oral cholera vaccine "Shanchol," which requires two doses 2–3 weeks apart. The vaccine is suitable for individuals over one year old, including pregnant women, and has minimal side effects such as mild abdominal pain or diarrhea. This resource aims to empower health promoters with practical knowledge to prevent and manage cholera outbreaks effectively.

The Ethiopia Multi-Sectorial Cholera Elimination Plan (2022-2028) outlines a national strategy to eliminate cholera in Ethiopia by 2028. The plan follows the Global Roadmap to End Cholera by 2030 and is based on six key pillars: Leadership & Coordination, Water, Sanitation & Hygiene (WASH), Surveill...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.
