Book (stand-alone)Technical bookEmergencia y respuesta a la influenza aviar de alta patogenicidad H5N1 en América Central, América del Sur y el Caribe
Informe técnico regional para el período octubre de 2022 a septiembre de 2024
2025Also available in:
En el presente informe se describe la emergencia sanitaria causada por la aparición por primera vez y la propagación del subtipo H5N1 de la influenza aviar de alta patogenicidad en los países de América Central, el Caribe y América del Sur, entre octubre del 2022 a septiembre del 2024. Se presenta el trabajo realizado con los 15 países que participaron en los proyectos de cooperación de la FAO para apoyar las estrategias de prevención y control implementadas frente al ingreso de la influenza aviar de alta patogenicidad y se aborda la experiencia acumulada en aspectos críticos que se presentaron durante la emergencia, junto a los desafíos para la prevención y mitigación de los riesgos de futuras incursiones de cepas de alta patogenicidad de la influenza aviar de alta patogenicidad en la región. -
Policy briefPolicy briefEvaluación preliminar conjunta de la FAO/OMS/OMSA sobre los virus recientes de la influenza A(H5N1)
23 de abril del 2024
2024Also available in:
Durante el 2020, los virus de la influenza aviar altamente patógena (IAAP) A(H5N1) del clado 2.3.4.4b surgieron a partir de virus de la influenza A(H5Nx) y se propagaron, predominantemente a través de aves migratorias, a muchas partes de África, Asia y Europa. La epizootia ha provocado un número sin precedentes de muertes en aves silvestres y ha causado brotes en aves de corral. A fines del 2021, estos virus llegaron a América del Norte y posteriormente a América del Sur, en octubre del 2022. Además, a escala mundial, cada vez más frecuentemente se han detectado virus A(H5N1) en especies no aviares, tales como mamíferos terrestres y marinos, silvestres y domésticos (de compañía y de granja). Recientemente, se han detectado en cabras y vacas lecheras de Estados Unidos de América. Con algunas excepciones regionales, la mayoría de los virus IAAP A(H5N1) caracterizados genéticamente desde el 2020 pertenecen al clado 2.3.4.4b. Desde principios del 2021, se han notificado a la OMS 28 detecciones de virus A(H5N1) en el ser humano, incluido un caso que estuvo expuesto a ganado bovino lechero presuntamente infectado por un virus A(H5N1). De estos casos humanos, 13 de los que se conoce el clado de hemaglutinina (HA) H5, han sido causados por virus del clado 2.3.4.4b. Esta evaluación de riesgos conjunta de la FAO, la OMS y la OMSA se centra en los virus A(H5N1) caracterizados desde el 2021 y evalúa el riesgo para la salud pública, así como el riesgo de propagación del virus en los animales.

Book (stand-alone)Technical bookThe future of food and agriculture - Trends and challenges 2017
Also available in:
No results found.What will be needed to realize the vision of a world free from hunger and malnutrition? After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021. -
Book (series)Manual / guidePreparing for Highly Pathogenic Avian Influenza 2009
Also available in:
No results found.Highly pathogenic avian influenza (HPAI) represents a threat to poultry industries worldwide and to people’s livelihoods, and a potential threat to human health. The international community has a vested interest in minimizing the spread of this disease. Countries may be under threat of introduction of highly pathogenic avian influenza through unregulated poultry trade and marketing practices and in rare occasions exposure of poultry to wild birds, especially waterfowl.The Food and Agricu lture Organization of the United Nations and the World Organisation for Animal Health prepared the first edition of this Manual to help national animal health authorities and other stakeholders prepare for a possible incursion of HPAI, detect disease as soon as possible and respond as rapidly as possible to contain the disease. This second edition reflects lessons learned and provides additional details.The manual offers practical advice on disease identification, pathology and diagnosis ; detection, response and control strategies; and biosecurity measures to prevent outbreaks. It is an invaluable source of useful information for anyone involved in poultry-keeping and animal health practices. -
Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
