Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or... drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

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.

Interim guidance 2 march 2021
Current use of drugs to prevent COVID-19 is variable, reflecting large-scale uncertainty. Numerous randomized trials of many different drugs are underway to inform practice. This first version of the Drugs to prevent COVID-19: A WHO living guideline contains new inform...ation and a recommendation on hydroxychloroquine. It follows the publication of six trials synthesized in a living network meta-analysis (NMA).

A manual for health care providers.
This manual provides expert guidance on the laboratory techniques and procedures used in the diagnosis of Buruli ulcer, a disease caused by Mycobacterium ulcerans. Aimed at laboratory technicians and scientists working on this disease, the manual details the exac...t procedures to follow when performing a range of diagnostic tests. Recommended procedures, intended for use throughout the health system, are presented at levels appropriate for peripheral, district and central services and in accordance with the varying resources, skills and equipment typically found in countries where Buruli ulcer is endemic.

Human use of land has been transforming Earth's ecology for millennia. From hunting and foraging to burning the land to farming to industrial agriculture, increasingly intensive human use of land has reshaped global patterns of biodiversity, ecosystems, landscapes, and climate. This review examines ...recent evidence from archaeology, paleoecology, environmental history, and model-based reconstructions that reveal a planet largely transformed by land use over more than 10,000 years. Although land use has always sustained human societies, its ecological consequences are diverse and sometimes opposing, both degrading and enriching soils, shrinking wild habitats and shaping novel ones, causing extinctions of some species while propagating and domesticating others, and both emitting and absorbing the greenhouse gases that cause global climate change. By transforming Earth's ecology, land use has literally paved the way for the Anthropocene.

On 15–16 December 2020, WHO and the Medicines for Malaria Venture co-convened a technical consultation to consider the preferred product characteristics (PPCs) for drugs used in malaria chemoprevention. The main goal of the technical consultation was to agree on the most important PPCs for drugs t...o protect populations from malaria (chemoprevention), while considering relevant measures of efficacy and the safety data needed to support WHO policy recommendations.

Le présent guide opérationnel sert de feuille de route pour la surveillance et les interventions en matière de mortalité maternelle et périnatale dans les milieux cliniques et politiques, comme décrit dans les deux guides de référence de l’Organisation mondiale de la santé (OMS) intitulé...s : Surveillance des décès maternels et riposte – Directives techniques – Prévention des décès maternels – Informations au service de l’action («Guide SDMR», 2013) et Pour que chaque enfant compte : audit et examens des mortinaissances et des décès néonatals» (2016).
Ces deux guides proposent des approches fondées sur l’utilisation de données de qualité sur les soins de santé pour mettre un terme aux décès maternels, aux mortinaissances et aux décès néonatals évitables.

A year ago, the second Special Session of the World Health Assembly (WHASS) unanimously agreed to start a diplomatic process for a new binding instrument aimed at ensuring the international community is better prepared for the next health emergencies. The establishment of an Intergovernmental Negoti...ating Body (INB) at the WHO paved the terrain for a proper negotiation, which has started to unfold. The INB will be releasing the “conceptual zero draft” of the treaty text in early December 2022.
