The global prevalence, morbidity and mortality related to childhood asthma among children has increased significantly over the last 40 years. Although asthma is recognized as the most common chronic disease in children, issues of underdiagnosis and undertreatment persist. There are substantial globa...l variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.

Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19.
2020 was one of the three warmest years on record. The past six years, including 2020, have been the si...x warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle.
The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change.

Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Early detection, assessment and response to acute public health events:
The global burden of disease associated with air pollution exposure exacts a massive toll on human health worldwide: exposure to air pollution is estimated to cause millions of deaths and lost years of healthy life annually. The burden of disease attributable to air pollution is now estimated to be ...on a par with other major global health risks such as unhealthy diet and tobacco smoking, and air pollution is now recognized as the single biggest environmental threat to human health.

The report brings a new dimension to long-term thinking about the future approach to these diseases. For the fi rst time, it sets out financing needs, options, and targets for meeting WHO Roadmap goals by 2020, but also for reaching universal coverage of all people in need by 2030. Th e report makes... one investment case for cost-eff ectiveness and a second investment case where equity is the focus. It sets targets for ending catastrophic health expenditures and, as part of the drive to strengthen health systems, for getting services closer to where people live.

This is the seventeenth annual publication of the Global Hunger Index (GHI), a report jointly published by Concern Worldwide and Welthungerhilfe.
The 2022 Global Hunger Index (GHI) brings us face to face with a grim reality. The toxic cocktail of conflict, climate change, and the COVID-19 pandemi...c had already left millions exposed to food price shocks and vulnerable to further crises. Now the conflict in Ukraine—with its knock-on effects on global supplies of and prices for food, fertilizer, and fuel—is turning a crisis into a catastrophe. But the speed and severity of the global food crisis reflects the fact that millions of people were already living on the precarious edge of hunger—a legacy of past failures to build more just, sustainable, and resilient food systems. This year’s report therefore focuses on food systems transformation and local governance.
According to the 2022 GHI, Hunger is at alarming levels in 5 countries—Central African Republic, Chad, Democratic Republic of the Congo, Madagascar, and Yemen— and is provisionally considered *alarming *in 4 additional countries— Burundi, Somalia, South Sudan, and Syria. In a further 35 countries, hunger is considered serious, based on 2022 GHI scores and provisional designations.

Progress in prevention and treatment is faltering around the world, putting millions of people in grave danger. Eastern Europe and central Asia, Latin America, and the Middle East and North Africa have all seen increases in annual HIV infections over several years. In Asia and the Pacific, UNAIDS da...ta now show new HIV infections are rising where they had been falling.

COVID-19 has heavily emphasized how contact tracing is crucial for managing outbreaks, and as part of the strategy for adjusting, and eventually lifting, lockdowns and other stringent public health and social measures. As the pandemic develops further, it will be a core measure to manage further wav...es of infection. In early June 2020, the World Health Organization (WHO) convened an online global consultation on contact tracing in the context of COVID-19, looking at the lessons of the pandemic to date; known and emerging best practices; and the measures necessary for urgent implementation, scale-up, maintenance and enhancement of contact tracing activities.
