This is the sixth of our 11-paper supplement entitled “Community Health Workers at the Dawn of New Era”. Expectations of community health workers (CHWs) have expanded in recent years to encompass a wider array
of services to numerous subpopulations, engage communities to collaborate with and to... assist health systems in responding to complex and sometimes intensive threats. In this paper, we explore a set of key considerations for training of CHWs in response to their enhanced and changing roles and provide actionable recommendations based on
current evidence and case examples for health systems leaders and other stakeholders to utilize.

This is the ninth paper in our series, “Community Health Workers at the Dawn of a New Era”. Community health workers (CHWs) are in an intermediary position between the health system and the community. While this position provides CHWs with a good platform to improve community health, a major cha...llenge in large-scale CHW programmes is the need for CHWs to establish and maintain benefcial relationships with both sets of actors, who may have diferent expectations and needs. This paper focuses on the quality of CHW relationships with actors at the local level of the national health system and with communities.

The case for evidence- based communication of science
This bi-weekly brief details the latest developments in scientific knowledge and public health policy from around the world as well as updates to the COVID-19-related guidance from Africa CDC, WHO and other public health agencies.
The COVID-19 pandemic led to school closures around the world, affecting almost 1.6 billion students. The effects of even short disruptions in a child’s schooling on their learning and well-being have been shown to be acute and long lasting. The capacities of education systems to respond to the cr...isis by delivering remote learning and support to children and families have been diverse yet uneven.
This report reviews the emerging evidence on remote learning throughout the global school closures during the COVID-19 pandemic to help guide decision-makers to build more effective, sustainable, and resilient education systems for current and future crises.

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.

The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).
