Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after expos...ure to a probable or confirmed case of SARS-CoV-2 infection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

In Central and West Africa, regions together comprising 27 countries and 605 million people, the average person is exposed to particulate pollution levels that are more than 4 times the World Health Organization’s (WHO) guideline of 5 μg/m³1. If... these particulate pollution levels persist, average life expectancy in the regions would be 1.6 years lower, and a total of 971 million person-years would be lost, relative to if air quality met the WHO guideline. The Democratic Republic of the Congo, Rwanda and Burundi, are the top three most polluted countries in the region.

Un an après le début de la pandémie, la COVID-19 a changé le monde et continue de peser sur notre quotidien. La pandémie a mis en évidence les lacunes des systèmes de santé tandis que le personnel de santé a été exposé au virus de façon...
disproportionnée. Tout au long de l’année passée, les infirmières ont affiché leur volonté et leur souplesse
en s’adaptant à de nouvelles méthodes de travail. Des millions d’infections à la COVID-19 ont été signalées parmi les agents de santé dans le monde et, hélas, le Conseil International des Infirmières (CII) a enregistré près de 3 000 décès qui lui sont
imputables parmi les infirmières dans 60 pays. Il est probable que le chiffre réel soit beaucoup plus élevé, le nombre d’infections et de décès parmi les agents de santé restant impossible à évaluer avec précision dans la mesure où de nombreux systèmes et pays n’ont pas assuré le suivi de cette question capitale.
Sur le long terme, les effets de la COVID-19, dont la « COVID longue » et le syndrome de stress posttraumatique différé, pourraient avoir d’importants effets délétères, en particulier sur le personnel infirmie

Overview
Early Adolescent Skills for Emotions (EASE) is an evidence-based group psychological intervention to help 10–15-year-olds affected by internalizing problems (e.g. stress and symptoms of anxiety, depression) in communities exp...osed to adversity. Published by the World Health Organization (WHO) and United Nations Children’s Fund (UNICEF), EASE aims to support adolescents and their caregivers with skills to reduce distress. The intervention consists of 7 group sessions for adolescents and 3 additional group sessions for their caregivers. It is based on adapted aspects from Cognitive Behavioral Therapy and has been designed to be suitable for delivery by trained and supervised non-specialist helpers.

The region of Latin America and the Caribbean (LAC) has high levels of income inequality and urbanization. This leaves a large percentage of the population exposed and vulnerable to infectious disease outbreaks (1). The COVID-19 outbreak occurred su...ddenly, within a complex economic, social and political context and at a time of low economic growth and high levels of informal labour. Structural challenges of poverty, deep inequality across different dimensions, and weak health and social protection systems exacerbated the region’s vulnerability to the pandemic

Air pollution is one of the leading causes of health complications and mortality worldwide, especially affecting lower-income groups, who tend to be more exposed and vulnerable. This study documents the relationship between ambient air pollution exp...osure and poverty in 211 countries and territories. Using the World Health Organization’s (WHO) 2021 revised fine particulate matter (PM2.5) thresholds, we show that globally, 7.3 billion people are directly exposed to unsafe average annual PM2.5 concentrations, 80 percent of whom live in low- and middle-income countries. Moreover, 716 million of the world’s lowest income people (living on less than $1.90 per day) live in areas with unsafe levels of air pollution, especially in Sub-Saharan Africa. Air pollution levels are particularly high in lower-middle-income countries, where economies tend to rely more heavily on polluting industries and technologies. These findings are based on high-resolution air pollution and population maps with global coverage, as well as subnational poverty estimates based on harmonized household surveys.

Tobacco kills up to half of its users who don’t quit (1-3).
Tobacco kills more than 8 million people each year, including an estimated 1.3 million non-smokers who are exposed to second-hand smoke Around 80% of the world's 1.3 billion tobacco user...s live in low- and middle-income countries.In 2020, 22.3% of the world’s population used tobacco: 36.7% of men and 7.8% of women.
To address the tobacco epidemic, WHO Member States adopted the WHO Framework Convention on Tobacco Control (WHO FCTC) in 2003. Currently 182 countries are Parties to this treaty.
The WHO MPOWER measures are in line with the WHO FCTC and have been shown to save lives and reduce costs from averted healthcare expenditure.

South Africa is a mineral-rich country. Although the mining of these minerals generates wealth for the country, it also causes diseases in the mine workers who are exposed to harmful dust. Pulmonary silicosis, the disease most commonly caused by exp...osure to crystalline silica dust, was described in South African gold miners in the early 1900s not many years after gold-mining commenced. Most studies since then have been cross-sectional, with only one large cohort study being conducted on white miners; long-term trends have not been reported. Currently, South Africa has one of the highest rates of silicosis in the world.

Silicosis is a group of occupational lung diseases caused by breathing in silica dust. It has been described since ancient times, when miners and stonecutters were exposed to dust containing this crystalline mineral.
Chronic obstructive pulmonary disease (COPD) is where air cannot get out of the lungs easily (the airflow is obstructed). COPD is a common condition that mainly affects middle-aged or older adults who smoke or have smoked. Jobs where people are expose...n>d to dust fumes and chemicals also increase the risk of COPD, as well as having chest trouble or asthma in childhood.

Beat the heat: child health amid heatwaves in Europe and Central Asia finds that half of these children died from heat-related illnesses in their first year of life. Most children died during the summer months.
"Around half of children across Europe and Central Asia – or 92 million children –... are already exposed to frequent heatwaves in a region where temperatures are rising at the fastest rate globally. The increasingly high temperatures can have serious health complications for children, especially the youngest children, even in a short space of time. Without care, these complications can be life-threatening,” said Regina De Dominicis UNICEF Regional Director for Europe and Central Asia.
Heat exposure has acute effects on children, even before they are born, and can result in pre-term births, low birth weight, stillbirth, and congenital anomalies. Heat stress is a direct cause of infant mortality, can affect infant growth and cause a range of paediatric diseases. The report also notes that extreme heat caused the loss of more than 32,000 years of healthy life among children and teenagers in the region.
As the temperatures continue to rise, UNICEF urges governments across Europe and Central Asia to:
- Integrate strategies to reduce the impact of heatwaves including through National Determined Contributions (NDC), National Adaptation Plans (NAP), and disaster risk reduction and disaster management policies with children at the centre of these plans
Invest in heat health action plans and primary health care to more adequately support heat-related illness among children
- Invest in early warning systems, including heat alert systems
- Adapt education facilities to reduce the temperatures in the areas children play in and equip teachers with skills to respond to heat stress
- Adapt urban design and infrastructure including ensuring buildings, particularly those housing the most vulnerable communities are equipped to minimize heat exposure
- Secure the provision of safe water, particularly in countries with deteriorating water quality and availability.
UNICEF works with governments, partners and communities across the region to build resilience against heatwaves. This includes equipping teachers, community health workers and families with the skills and knowledge to respond to heat stress.

To implement the set of recommendations on the marketing of foods and non-alcoholic beverages to children
With the growing obesity crisis among children, WHO and other public health advocates and consumer groups have called for restrictions on advertising of ‘unhealthy foods’ high in salt, ...sugar and fat to children. Each day, children in the South East Asia Region are exposed to large volume of marketing of unhealthy foods that may influence children’s food preferences and consumption patterns and is associated with childhood overweight and obesity.
The definition of ‘unhealthy’ is debatable, and therefore, an objective method of describing foods as healthy or unhealthy is needed. A nutrient profile model does just that and therefore, a nutrition profile model for South East Asia was developed. The model is consistent with international guidance for preventing chronic disease and is a simple system with clear cut-offs for defining which foods are not suitable for advertising to children.
