Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

This report summarizes the latest scientific knowledge on the links between exposure to air pollution and adverse health effects in children. It is intended to inform and motivate individual and collective action by health care professionals to prevent damage to children’s health from exposure to ...air pollution. Air pollution is a major environmental health threat. Exposure to fine particles in both the ambient environment and in the household causes about seven million premature deaths each year. Ambient air pollution (AAP) alone imposes enormous costs on the global economy, amounting to more than US$ 5 trillion in total welfare losses in 2013.

The GHS Index is intended to be a key resource in the face of increasing risks of high-consequence and globally catastrophic biological events and in light of major gaps in international financing for preparedness. These risks are magnified by a rapidly changing and interconnected world; increasing ...political instability; urbanization; climate change; and rapid technology advances that make it easier, cheaper, and faster to create and engineer pathogens.
Key findings from the study of 195 countries:
• Out of a possible 100 points, the average GHS Index score across 195 countries was 40.2.
• The majority of high- and middle-income countries do not score above 50.
• Action is urgently needed to improve countries’ readiness for high-consequence infectious disease outbreaks.

Air pollution is a major environmental health threat. Exposure to fine particles in both the ambient environment and in the household causes about seven million premature deaths each year. Ambient air pollution alone imposes enormous costs on the global economy, amounting to more than US$ 5 trillion in total welfare losses in 2013.
This public health crisis is receiving more attention, but one critical aspect is often overlooked: how air pollution affects children in uniquely damaging ways. Recent data released by the World Health Organization (WHO) show that air pollution has a vast and terrible impact on child health and survival. Globally, 93% of all children live in environments with air pollution levels above the WHO guidelines (see the full report, Air pollution and child health: prescribing clean air. More than one in every four deaths of children under 5 years of age is directly or indirectly related to environmental risks. Both ambient air pollution and household air pollution contribute to respiratory tract infections that resulted in 543 000 deaths in children under the age of 5 years in 2016.

Lessons from three African Countries.
Achieving Health for All, and in particular universal health coverage (UHC), will not happen without fully functioning basic water, sanitation and hygiene (WASH) services in all health care facilities. Such services are needed to provide quality care, ensure ad...herence to infection prevention and control (IPC) norms and standards and guarantee that facilities are able to provide environments that respect the dignity and human rights of all care seekers, especially mothers, newborns and children. WHO undertook a series of national situational analyses in three countries (Ghana, Ethiopia and Rwanda) to understand current barriers to change, accountability structures and measures to strengthen WASH in health care facilities and more broadly, the quality of health service delivery.

The Ministry of Education, Arts and Culture (MoEAC) has been implementing the Integrated School Health Programme in various forms since before the country attained political independence in 1990. School health goes beyond the physical health of the learner, in that it includes the holistic wellbeing... of the individual learner, meaning that the school environment should be safe and conducive to learning. The National Safe Schools Framework (NSSF) is an exciting dimension of the Integrated School Health Programme. The Programme focuses on promoting the health, safety and wellbeing of learners and other school stakeholders in Namibia, and the NSSF was developed to provide practical guidance to the schools and school stakeholders on how to systematically improve the standards of school safety, and how to develop a culture of care in any school.

Non-Communicable Diseases (NCDs) have emerged as conditions of great public health concern in Kenya accounting for 39% of deaths annually. The Ministry of Health through the Department of Non-Communicable Diseases has adopted the vision of achieving a nation free from preventable burden of NCDs. Fur...ther, the mission of this strategy is to halt and reverse the rising burden of NCDs through effective multisectoral collaboration and partnerships by ensuring Kenyans receive the highest attainable standard of NCD continuum of care that is accessible, affordable, quality, equitable and sustainable thus alleviating suffering, disease and death for their well-being and socio-economic development.
The scope of NCDs covered by this strategy include; cardiovascular diseases, cancer, diabetes, chronic respiratory diseases, mental health conditions, violence and injuries, hemoglobinopathies, haemophilia and other bleeding disorders, auto immune diseases, chronic renal diseases, epilepsy and other neurological disorders, chronic skin conditions and oral diseases and conditions. It equally addresses seven risk factors; tobacco use, harmful use of alcohol, unhealthy diets and toxins, physical inactivity, indoor air pollution, environmental pollutants and toxins and stress.

he aetiology of asthma and allergic disease remains poorly understood, despite considerable research. The International Study of Asthma and Allergies in Childhood (ISAAC), was founded to maximize the value of epidemiological research into asthma and allergic disease, by establishing a standardized m...ethodology and facilitating international collaboration. Its specific aims are: 1) to describe the prevalence and severity of asthma, rhinitis and eczema in children living in different centres, and to make comparisons within and between countries; 2) to obtain baseline measures for assessment of future trends in the prevalence and severity of these diseases; and 3) to provide a framework for further aetiological research into genetic, lifestyle, environmental, and medical care factors affecting these diseases. The ISAAC design comprises three phases. Phase 1 uses core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations. Phase 2 will investigate possible aetiological factors, particularly those suggested by the findings of Phase 1. Phase 3 will be a repetition of Phase 1 to assess trends in prevalence.

The study analyses the current situation of children with disabilities in relation to realizing their rights and accessing basic services, as well as their life experiences in their communities. It also focuses on identifying the barriers created by society that prevent children with disabilities fr...om enjoying their human rights. This includes identifying negative attitudes; environmental and communication barriers; gaps in policies or their effective implementation.
The report reveals that children with disabilities in Myanmar are less likely to access services in health or education; rarely have their voices heard in society; and face daily discrimination as objects of pity. It also highlights how inadequate policies and legislation contribute to the challenges these children face.
The information available in this publication should be useful for policy makers, development partners and Disabled Persons Organisations to promote the realization of the rights of all children with disabilities.

Three billion people – 40 per cent of the world’s population – do not have a place in their homes to wash their hands with water and soap. Three quarters of those who lack access to water and soap live in the world’s poorest countries and are amongst the most vulnerable: children and familie...s living in informal settlements, migrant and refugee camps, or in areas of active conflict. This puts an estimated 1 billion people at immediate risk of COVID-19 simply because they lack basic handwashing facilities.
The Hand Hygiene for All initiative aims to move the world towards this goal: supporting the most vulnerable communities with the means to protect their health and environment. It brings together international partners, national governments, public and private sectors, and civil society to ensure affordable products and services are available, especially in disadvantaged areas, and to enable a culture of hygiene.

Alcohol consumption is deeply embedded in the social landscape of many societies. Several major factors have an impact on levels and patterns of alcohol consumption in populations – such as historical trends in alcohol consumption, the availability of alcohol, culture, economic status and trends i...n the marketing of alcoholic beverages, as well as implemented alcohol control measures. At the individual level, the patterns and levels of alcohol consumption are determined by many different factors, including gender, age and individual biological and socioeconomic vulnerability factors, as well as the policy environment. Prevailing social norms that support drinking behaviour and mixed messages about the harms and benefits of drinking encourage alcohol consumption delay appropriate health-seeking behaviour and weaken community action
