This report presents an analysis of antibacterial agents in preclinical (third annual review) and clinical (fifth annual review) development. The analysis covers traditional (direct-acting small molecules) and non-traditional antibacterial agents in development worldwide. It evaluates to what extent... the present pipeline addresses infections caused by WHO Priority Pathogens, Mycobacterium tuberculosis and Clostridioides difficile. The report also provides an assessment of the traditional agents with respect to whether they meet a set of predefined criteria for innovation, namely absence of known cross-resistance, new target, mode of action and/or class. It also includes an overview of the agents that obtained authorization since 1 July 2017.

Although Shiga toxin-producing Escherichia coli (STEC) have been isolated from a variety of food production animals, they are most commonly associated with ruminants from which we derive meat and milk. Because of the widespread and diverse nature of ruminant-derived food production, coupled with the... near ubiquity of STEC worldwide, there is no single definitive solution for controlling STEC that will work alone or in all situations. Instead, the introduction of multiple interventions applied in sequence, as a “multiple-hurdle scheme” at several points throughout the food chain (including processing, transport and handling) will be most effective.
This report summarizes the review and evaluation of interventions applied for the control of STEC in cattle, raw beef and raw milk and raw milk cheese manufactured from cows’ milk, and also evaluates available evidence for other small ruminants, swine and other animals. The information is presented from primary production, to the end of processing, providing the reader with information on the currently available interventions based on the latest scientific evidence.
This work was undertaken to support the development of guidelines for the control of STEC in beef, raw milk and cheese produced from raw milk by the Codex Committee on Food Hygiene (CCFH).

At its 48th session of Codex Committee on Food Hygiene (CCFH), the Committee noted the importance of water quality and safety in food production and processing. CCFH requested the Food and Agriculture Organization of the United Nations
(FAO) and the World Health Organization (WHO) to provide guidan...ce for those scenarios where the use of “clean water” (i.e. water that does not compromise the safety of the food in the context of its use) was indicated in Codex texts and on
where it is appropriate to use “clean water”. In particular, guidance was sought for the use of irrigation water and “clean” seawater and on the safe reuse of processing water.

This publication describes the first WHO public-benefit Target Product Profiles (TPPs) for snakebite antivenoms. It focuses on antivenoms for treatment of snakebite envenoming in sub-Saharan Africa. Four TPPs are described in the document:
Broad spectrum Pan-African polyvalent antivenoms: products ...that are intended for widespread utility throughout sub-Saharan Africa for treatment of envenoming irrespective of the species of snake causing a bite. Monovalent antivenoms for specific use cases: for products for a single species (or genus) of snake (e.g., boomslangs or carpet viper antivenoms).
Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.

The waves of yellow fever transmission in the Region of the Americas in 2016–2018 involved the largest number of human and epizootic cases to be reported in several decades. Yellow fever is a serious viral hemorrhagic disease that poses a challenge for health professionals. It requires early recog...nition of signs and symptoms, which are often nonspecific, and it can mimic other acute febrile syndromes. Early detection of suspected or confirmed cases, monitoring of vital signs, life support measures, and treatment of acute kidney failure continue to be the recommended strategies for case management. This report is the result of discussions among experienced specialists in the Americas on the clinical management of yellow fever patients, especially during outbreaks and epidemics, in the context of current medical and scientific evidence and taking into account the technical guidelines already available in the countries of the Region. It includes flowcharts for initially addressing patients with clinical suspicion of yellow fever and proposes a minimum package of laboratory tests that may be useful in contexts where resources are limited. In addition, it considers aspects of health system organization for dealing with yellow fever outbreaks and epidemics.

Las olas de transmisión de la fiebre amarilla ocurridas en la Región de las Américas entre el 2016 y el 2018 causaron el mayor número de casos humanos y epizoóticos registrados en varios decenios. La fiebre amarilla es una enfermedad hemorrágica viral grave que representa un desafío para el p...rofesional de salud: exige el reconocimiento temprano de signos y síntomas muchas veces inespecíficos, que pueden parecerse a otros síndromes febriles agudos. La detección temprana de los casos sospechosos o confirmados, el monitoreo de los signos vitales y las medidas de soporte vital, y el tratamiento de la insuficiencia hepática aguda siguen siendo las estrategias recomendadas para el manejo de los casos. El presente informe es el resultado de las deliberaciones sobre la experiencia de expertos de la Región en cuanto al manejo clínico de pacientes con fiebre amarilla, especialmente en brotes y epidemias, mediante la contextualización de esa experiencia en el conjunto actual de la evidencia médico-científica y la consideración de las directrices técnicas ya disponibles en los países de la Región. Presenta flujogramas para la evaluación inicial del paciente con sospecha clínica de fiebre amarilla y sugiere un conjunto mínimo de pruebas de laboratorio que puede ser útil cuando hay pocos recursos; además, detalla aspectos de la organización de los sistemas de salud para enfrentar brotes y epidemias de fiebre amarilla.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.
