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.
A person who lives in or has traveled in the previous 14 days to areas with dengue transmission, and presents with acute fever that has typically lasted 2 to 7 days, and two or more of the following clinical manifestations: nausea or vomiting, exanthema, headache or retro-orbital pain, myalgia or ar...thralgia, petechiae or positive tourniquet test (+), leukopenia, with or without any warning sign or sign of severity.

This publication aims to provide updated guidance on the specific use of yellow fever laboratory assays in the context of surveillance to be used across the Global Yellow Fever Laboratory Network for disease surveillance. In the recent years, new commercial assays became available and are now recomm...ended for use by WHO and this publication will support national program on the use of compound laboratory assays as per the most recent recommended testing algorithms. This piece is aligned with the elimination effort set in the comprehensive global strategy to eliminate yellow fever epidemics (EYE) strategy 2017-2026 and where its advisory laboratory technical working group actively contributed to its development. The target audiences are policy-makers and health workers.

The Pandemic Influenza Preparedness (PIP) Framework is a World Health Assembly resolution adopted unanimously by all Member States in 2011. It brings together Member States, industry, other stakeholders and WHO to implement a global approach to pandemic influenza preparedness and response. The Frame...work includes a benefit-sharing mechanism called the Partnership Contribution (PC). The PC is collected as an annual cash contribution from influenza vaccine, diagnostic, and pharmaceutical manufacturers that use the WHO Global Influenza Surveillance and Response System (GISRS). Funds are allocated for: (a) pandemic preparedness capacity building; (b) response activities during the time of an influenza pandemic; and (c) PIP Secretariat for the management and implementation of the Framework.

This toolkit is a comprehensive set of practical tools and resources designed to support country-level risk communication and community engagement (RCCE) practitioners, decision-makers, and partners to plan and implement readiness and response activities for dengue fever outbreaks. The toolkit conta...ins: information about dengue fever; RCCE considerations for how to approach key issues during dengue fever outbreaks; tools for understanding the context in which dengue fever outbreaks occur; methods for collecting data to inform strategy development and bring evidence into planning and implementation of activities; guidance to support vector control and prevention activities; case studies; and links to existing RCCE tools and training. It is one of a suite of toolkits on RCCE readiness and response to a range of disease and response areas.

The monkeypox virus (MPXV) clade I epidemic that has been affecting the Democratic Republic of the Congo
(DRC) since November 2023 has recently spread to several other African countries including Burundi, Rwanda,
Uganda and Kenya. The size of these outbreaks could be larger than reported due to un...der-ascertainment and

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.

WHO has updated the mpox Case reporting form (CRF) and data collection tool, mainly by reducing the number of variables. A detailed list of changes is presented in the file. The content of the Case investigation form (CIF) has not been changed.
On 14 August 2024, the Director-General of the World Health Organization determined that the upsurge of mpox in a growing number of countries in Africa constitutes a new public health emergency of international concern (PHEIC) under the International Health Regulations (IHR) (2005)
This is the 42nd situation report for the multi-country outbreak of mpox, which provides an update on the epidemiological situation of mpox in Africa (including countries in the WHO African Region and some countries in the WHO Eastern Mediterranean Region), with data as of 3 November 2024.
