Alcohol use is deeply embedded in the social landscape of many societies, and some 2300 million people drink alcoholic beverages in most parts of the world. At the same time, more than half of the global population aged 15 years and older reported having abstained from drinking alcohol during the pr

evious 12 months. 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 implemented alcohol control measures. At the individual level the patterns and levels of alcohol consumption are determined by multiple factors that include 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 may encourage alcohol consumption, delay appropriate health-seeking behaviour and weaken community action.

ted by WHO from Member States and organized in accordance with the Sustainable Development Goals health target 3.5 which calls on countries to strengthen “the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol”. The chapter on alcohol and health continues the series of WHO global status reports on alcohol and health and presents the latest available data on the status of, and trends in, alcohol consumption, as well as estimates of the alcohol-attributable disease burden and descriptions of policy responses worldwide. On the basis of data collected from countries on the treatment of substance use disorders the report describes the status of key components of treatment responses to alcohol and drug use disorders and proposes a new service capacity index for these disorders as an additional contextual indicator for monitoring progress in this domain of SDG health target 3.5. The report concludes with broad directions for international action to accelerate progress towards achievement of SDG health target 3.5.

COPD care contributes to preventive and management challenges. Thus, the majority of patients with COPD are misdiagnosed, misclassified and mismanaged or undertreated. With the struggling improvement in the quality of healthcare in Africa, studies conducted over the last 10 years indicates the rising trends in both the risk factors and the burden of COPD. The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.

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.

symptoms, with marked variations in prevalence and in prevalence trends between countries and regions of the world. The Global Burden of Disease Study estimated that asthma caused the loss of 21.6 million healthy years of life (disability-adjusted life years) and 461 069 deaths in 2019. Approximately 90% of the asthma burden of disease is borne by people living low and middle income countries (LMICs). Some countries report very high (up to 90%) rates of uncontrolled asthma. While the prevalence of asthma is highest in countries with a high Socio-Demographic Index (SDI), death rates from asthma are highest in countries with low and lower middle incomes.

opportunities to meet their full potential.
We can and must do better.
The future of childhood hangs in the balance.
This year’s State of the World’s Children Report examines the forces and trends shaping our world today and reflects on how they might shape the future.
The report explores three megatrends that will profoundly impact children’s lives between now and 2050: demographics shifts, the climate and environmental crises and frontier technologies.
It also presents three future scenarios – possible outcomes, not predictions – for how children could experience the world of 2050.
As we consider what we can do today, our responsibility is clear: now is the time to shape a better future for every child.

Although it is still too early to gauge whether the COVID-19 pandemic has altered long-term trends in health spending, spending appears to have peaked and is now at or below its long-term rising trend in most country income groups. Additionally, to mark the 25th anniversary of the World Health Organization’s (WHO) Health Expenditure Tracking Program, the report reviews the program’s achievements and envisions a path forward. As the program’s lead technical agency, WHO is committed to working closely with partners to support countries in tracking health spending and sustaining the Global Health Expenditure Database and the Global Health Expenditure Report as global public goods.

Emerging data and trends show that these potential returns have increased during the COVID-19 pandemic - investments in social determinants can mitigate widespread reductions in human capital and the increasing likelihood of costly syndemics, while promoting access to healthcare innovations that have thus far been inequitably distributed. Therefore, we argue that, despite immediate fiscal pressures, this is exactly the time to invest in health equity and its broader social determinants, as the returns on such investments have never been greater.

plications of P. falciparum HRP2/3 gene deletions, which compromise the accuracy of the widely used HRP2-detecting rapid diagnostic tests (RDTs). The report analyses the malaria RDT market, noting supplier diversification, price trends and production shifts resulting from the pandemic. It also addresses the emerging point-of-care G6PD testing market, which is required to ensure the safe radical cure of P. vivax infections. It surveys technological innovation, including digital microscopy, hemozoin tests, nucleic acid detection and biosensors, while emphasising that RDTs and microscopy will remain the mainstay of case management in the near term. The report identifies market shortcomings, access barriers and opportunities to improve malaria case management and diagnostic coverage.

trends suggest, the world could face an additional 1.1 million new HIV infections and 820,000 additional deaths by 2040. In this worst-case scenario, by 2040, three million children would acquire HIV and nearly 1.8 million would die of AIDS-related causes — the vast majority in sub-Saharan Africa. These are not statistics; they are children with dreams, families, and futures. They represent our shared humanity — and our collective failure if we do not act.
