Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

Many African countries were amongst the most rapid to respond to the emerging threat of COVID-19, implementing large-scale interventions at very early stages of their epidemic. As demonstrated in this document using very simple models, this rapid mobilization and timeliness of implementing control m...easures is likely to be an important determinant of their success. Indeed, as these measures were relaxed, subsequent waves of disease have been observed in many countries including South Africa, Kenya, Tunisia, Morocco, Sudan and the Democratic Republic of Congo (DRC) where such waves have severely impacted the health system by straining the supply of oxygen and ICU beds and inflicting a heavy toll on healthcare workers, often necessitating the re-imposition of control measures.

Has the world worked together to tackle the coronavirus? July 2021. This research paper assesses how the global community has responded to calls for greater solidarity in tackling the COVID-19 pandemic, and presents the insights of key stakeholders and experts in global health governance, health sec...urity, and pandemic preparedness and response. The authors examine the state of solidarity at global, regional and national levels, and present case studies on COVAX and on the EU’s turbulent journey through solidarity.

Almost two years after the signing of the Political Accord for Peace and Reconciliation (APPR), the Central African population is still hostage to an unstable and unpredictable security environment. Continuing conflicts in several areas of the country, structural weaknesses combined with the socio-e...conomic effects of the COVID-19 pandemic, and the devastating effects of natural disasters have plunged 2.6 million people into dire needs. Of this total, 1.6 million have severe humanitarian needs, a figure unmatched for five years, reflecting a deterioration in the physical and mental well-being and living conditions of populations across the country.

When situations occur in which unwanted events are rightly or wrongly connected with vaccination, they may erode confidence in vaccines and the authorities delivering them. This document presents the scientific evidence behind WHO’s recommendations on building and restoring confidence in vaccines ...and vaccination, both in ongoing work and during crises. The evidence draws on a vast reserve of laboratory research and fieldwork within psychology and communication. It examines how people make decisions about vaccination; why some people are hesitant about vaccination; and the factors that drive a crisis, covering how building trust, listening to and understanding people, building relations, communicating risk and shaping messages to the audiences may mitigate crises. This document provides a knowledge base for stakeholders who develop communication strategies or facilitate workshops on communication and trust-building activities in relation to vaccines and immunization, such as immunization programme units, ministries of health, public relations and health promotion units, vaccine safety communication trainers and immunization advisory bodies.

The Compendium of data and evidence-related tools for use in TB planning and programming was developed as a companion document to the People-centred framework for tuberculosis programme planning and prioritization – user guide, published by the World Health Organization (WHO)... in 2019. The compendium is intended to support implementation of the people-centred framework user guide. It can also be used independently to inform decisions taken by national tuberculosis (TB) programmes about the implementation of the tools included in this document.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

Les infections au SRAS-CoV-2 chez les enfants et les adolescents provoquent une maladie moins grave et moins de décès que chez les adultes. Bien qu'une évolution moins grave de l'infection soit un résultat positif, on s'inquiète du fait que des symptômes légers aient pu conduire à moins de t...ests, ce qui a entraîné un nombre moins important de cas identifiés de COVID-19 chez les enfants. Si les enfants présentant des symptômes légers ou inexistants transmettent la maladie, ils peuvent agir comme des vecteurs de transmission au sein de leur communauté. Il est essentiel de comprendre les symptômes, l'infectivité et les modes de transmission du SRAS-CoV-2 chez les enfants et les adolescents pour développer, adapter et améliorer les mesures de contrôle du COVID-19 à tous les âges. Ce document est un résumé des connaissances actuelles concernant l'acquisition et la transmission de l'infection par le SRAS-CoV-2 et les symptômes de la maladie COVID-19 chez les enfants et les adolescents. Il vise à éclairer les décisions, en fonction des contextes locaux, sur la meilleure façon de maintenir ouvertes les écoles, les jardins d'enfants et les crèches et sur les conseils à appliquer en matière de mixité intergénérationnelle.

Development of one or more vaccines for Neisseria gonorrhoeae is an important objective for sexual and reproductive health worldwide, and for the fight against antimicrobial resistance.
WHO preferred product characteristics (PPCs) provide strategic guidance as to WHO’s preferences for new vacci...nes in priority disease areas. PPCs are intended to encourage innovation and development of vaccines for use in settings most relevant to the global unmet public health need.
Gonococcal vaccine PPCs describe global public health goals for gonococcal vaccines and preferred parameters pertaining to vaccine indications and target populations, safety and efficacy considerations, and immunization strategies.
