La presente publicación describe la evidencia científica disponible sobre la precisión diagnóstica de las pruebas rápidas de detección de antígenos para SARS-COV-2. El conocimiento de las pruebas diagnósticas para el coronavirus del síndrome respiratorio agudo grave 2 (SARS-COV-2) sigue evo...lucionando, y una comprensión clara de la naturaleza de las pruebas y la interpretación de sus hallazgos es importante. Este punto de vista describe cómo interpretar 2 tipos de pruebas diagnósticas comúnmente en uso para las infecciones SARS-COV-2: reacción en cadena de polimerasa con transcriptasa reversa (RT-PCR) y ensayo por inmunoabsorción ligado a enzimas IgM e IgG (ELISA)— y cómo los resultados pueden variar con el tiempo.

This report aims to support countries in the necessary transition toward healthier, more sustainable diets by integrating biodiversity in food-based interventions to support nutrition and health. It is intended to help guide decision-makers in the health, nutrition and other sectors, to:
Consider... the important role of biodiversity in food systems for the development of integrated interventions to support healthy, diverse and sustainable diets;
To focus investments and country support for more comprehensive, coordinated and cross-cutting public health and nutrition projects and policies; and
To strengthen the resilience of food systems, health systems, and societies, each of which are each increasingly compromised by widespread ecological degradation, biodiversity loss and climate change.
Biodiversity at every level (genetic, species and ecosystem level) is a foundational pillar for food security, nutrition, and dietary quality. It is the basic source of variety in essential foods, nutrients, vitamins and minerals, and medicines, and underpins life-sustaining ecosystem services. It is a core environmental determinant of health, often a vital ingredient of healthy nutritional outcomes and livelihoods, gender equality, social equity, and other health determinants.
Biodiversity can play a more prominent role in planning for nutritional outcomes in various ways, e.g. by facilitating the production of nutritious fruits and plant products, sustaining livelihoods through more efficient production and increasing the diversity of products available in markets. This Guidance presents and expands on six core building blocks for mainstreaming biodiversity for nutrition and health:
Cross-sectoral knowledge development and knowledge co-production;
Enabling environments;
Integration;
Conservation and the wider use of biodiversity;
Education and awareness-raising;
Monitoring and evaluation;
This WHO report builds on an unprecedented opportunity to mainstream biodiversity in order to support healthy and sustainable diets, and offers the necessary technical guidance to catalyze and support a transformation of the global food system and transition to healthier, more sustainable diets.

Food environments are usually defined as the settings with all the different types of
food made available and accessible to people as they go about their daily lives.
That is, the range of food in supermarkets, small retail outlets, wet markets, street
food stalls, coffee shops, tea houses, s...chool canteens, restaurants, and all the other
venues where people buy and eat food. These environments differ enormously depending on the context. They can be extensive and diverse, with a seemingly endless array of options and price ranges, or they can be sparse, with very few options on offer. Because they determine what food consumers can access at a given moment in time, at what price, and with what degree of convenience, food environments both constrain and prompt the consumer’s choice.Food environments are influenced by the food systems which supply them, and vice versa. Food systems encompass the entire range of activities, people and institutions involved in the production, processing,
marketing, consumption and disposal of food (FAO, 2013). They include but are not limited to food supply chains. Making food systems nutrition-sensitive can contribute to addressing all forms of malnutrition, as food systems determine whether the food needed for good nutrition are available, affordable, acceptable and of adequate
quantity and quality. How closely food systems and food environments are interrelated and interdependent, and the degree to which external factors affect nutrition outcomes, varies from setting to setting.Many of today’s food systems
and food environments are challenged in supporting consumer choices that are
consistent with healthy diets and good nutrition. Consumers are not making choices based on nutrition and health, and poor diet is now the number one risk factor for death and disability worldwide (GBD, 2015). Food systems that do not enable healthy diets are increasingly recognized as an underlying cause of malnutrition (GLOPAN, 2016), and malnutrition, irrespective of form, has a huge cost. Economic costs associated with undernutrition are estimated at $1-2 trillion per year, about 2-3% of global GDP (FAO, 2013); the global economic cost of obesity and associated diet-related non-communicable diseases is estimated at $2 trillion per year, about 2.8% of global GDP (McKinsey, 2014). Influencing food environments for promoting healthy diets is an emerging strategy to address today’s nutrition challenges.

This document focus on the direct consequences of the virus (morbidity and mortality) in specific populations and on the results of measures aimed at mitigating the spread of the virus, with indirect impacts on socio-economic conditions. In this complex scenario, the gender approach has not received... due attention during the pandemic. Gender is one of the structural determinants of health, but it does not appear in analyses of the direct and indirect effects of the pandemic, despite being essential in the recognition and analysis of the differential impacts on men and women and their interaction with the different determinants of health.
