This manual has been developed to guide rapid risk assessment of acute public health risks from any type of hazard in response to requests from Member States of the World Health Organization (WHO). The manual is aimed primarily at national departments with health-protection responsibilities, Nationa...l Focal Points (NFPs) for the International Heath Regulations (IHR) and WHO staff. It should also be useful to others who join multidisciplinary risk assessment teams, such as clinicians, field epidemiologists, veterinarians, chemists, food-safety specialists.

Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by venom being sprayed into a person’s eyes by certain species of snakes tha...t have the ability to spit venom as a defence measure. Not all snakebites result in envenoming: some snakes are non-venomous and venomous snakes do not always inject venom during a bite. About 50–55% of all snakebites result in envenoming. Snake venoms are complex mixtures of protein and peptide toxins, varying from one species to another, and even within species. The toxins in snake venoms are evolutionarily adapted to interact with a large variety of cellular targets in the organisms exposed to them. In humans and animals, snakebite envenoming affects multiple organ systems (depending on the particular species of snake and the classes of toxins present in the venom) and can cause, among other things: haemorrhage and prolonged disruption of haemostasis, neuromuscular paralysis, tissue necrosis, myolysis (muscle degeneration), cardiotoxicity, acute kidney injury, thrombosis and hypovolaemic shock.

L’Assemblée mondiale de la Santé, tenue en mai 2015, a adopté un Plan d’action mondial pour combattre la résistance aux antimicrobiens, qui définit 5 objectifs:
mieux faire connaître et comprendre le problème de la résistance aux antimicrobiens grâce à une communication, une éduc...ation et une formation efficaces;
renforcer les connaissances et les bases factuelles par la surveillance et la recherche;
réduire l’incidence des infections par des mesures efficaces d’assainissement, d’hygiène et de prévention des infections;
optimiser l’usage des médicaments antimicrobiens en santé humaine et animale;
dégager les arguments économiques en faveur d’investissements durables qui tiennent compte des besoins de tous les pays et accroître les investissements dans la mise au point de nouveaux médicaments, outils diagnostiques, vaccins et autres interventions.

The meeting addressed the last key area, that is, determining the best method or combination of diagnostic methods for a control programme for S. stercoralis infections in humans.
Dr Montresor’s presentation highlighted that while there is currently no “gold standard” for the... diagnosis of S. stercoralis, there is a felt urgency to optimize diagnostic regimens that are currently available, and in the context of population-based testing (as opposed to individual focused diagnostics in clinical settings).
In other words, the diagnostic test(s) should have good accuracy, but we should remember that in public health we do not aim at individual diagnosis: rather, we need a tool that should help to estimate the prevalence in a population.

The following Emergency Response Plan for the COVID-19 pandemic seeks to set out activities that will be undertaken by humanitarian actors in Ukraine over the course of 2020 to respond to the public health impact of the epidemic – as well as the indirect, socio-economic impact on people’s well-b...eing, which will span across many areas. Given the extensive public exposure of the COVID-19 threat, the response will cover the whole of Ukraine, while providing a distinct focus on Donetska and Luhanska oblasts that have been ravaged by an armed conflict for the last six consecutive years. The planned COVID-19 response in the two conflict-affected oblasts will be treated as an annex to the current Humanitarian Response Plan for Ukraine

This report presents the findings of the Estimating the Size of Populations through a Household Survey (ESPHS) study that took place in 2011. The study utilized a single household survey to estimate the size of several key populations, including sex workers, men who have sex with men (MSM), injectin...g drug users (IDU), and clients of sex workers. These populations include several groups outlined in the National Strategic Plan for HIV and AIDS as most at risk for HIV infection, specifically sex workers and MSM.

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec
le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les
populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

Weekly Epidemiological Record No 9, 2022, 97, 61–80
This position paper supersedes the 2016 publication, “Malaria vaccine: WHO position paper-2016.”1 It includes the updated WHO recommendations on the wider use of the RTS,S/AS01 vaccine for the reduction of malaria morbidity and mortality in ...children living in areas of moderate to high malaria transmission. It also incorporates findings from the evaluation of the WHO-coordinated Malaria Vaccine Implementation Programme (MVIP), recommended by SAGE and MPAG in 2015, and from additional studies since 2015.
This paper does not include findings on vaccine efficacy in infants first vaccinated at 6–12 weeks of age. Because of the lower vaccine efficacy observed in this age category, WHO did not recommend pilot implementation or RTS,S/AS01 vaccine introduction for these young infants. Recommendations2 on the use of RTS,S/AS01 vaccine were discussed by SAGE and MPAG during a joint session in October 2021; evidence presented at the meeting can be accessed at https://terrance.who.int/mediacentre/data/ sage/SAGE_eYB_Oct2021.pdf

La maladie à virus Ebola (MVE) est une maladie multisystémique potentiellement mortelle qui entraîne souvent une hypovolémie, une acidose métabolique, une hypoglycémie et une défaillance multi-viscérale. L'épidémie prolongée de MVE en Afrique de... l'Ouest en 2013-2016 a permis une évolution dans le domaine des soins telle qu'à la fin de l'épidémie, de nombreux patients ont pu recevoir des soins de support individualisés et optimisés, dont la réanimation hydro-électrolytique, le contrôle des symptômes, la surveillance biologique en laboratoire et au chevet de la glycémie et des électrolytes, la prise en charge des défaillances d’organe, ainsi que la détection et le traitement rapides des co-infections, contribuant ainsi à une réduction de la mortalité.
Toutefois, le niveau des soins varie considérablement d'un centre de traitement Ebola (CTE) à l'autre, au cours de la même épidémie, ainsi que d’une épidémie à l’autre

“Because we struggle to survive” Child Labour among Refugees of the Syrian Conflict | This study provides pertinent first-hand information on the reality facing Syrian children who are working either in their homeland, the neighbouring countries or elsewhere in Europe. Syria's civil war is the w...orst humanitarian crisis of our time. Hundreds of thousands of people - adults and children alike - have been killed. Two thirds of all Syrians have lost their homes and their livelihoods. Millions of Syrians have been uprooted from their home communities and forced to flee within their country or to neighbouring countries. The consistent spill-over has drawn global attention not just to the humanitarian crisis facing both local communities and national governments but also to the economic and social strain. The bloodshed wreaked by the different parties continues. The suffering deepens. Approximately half of the Syrian refugees and displaced persons are children and young people who suffer from a double-vulnerability: as children and as migrants or refugees.
