When setting national drinking-water quality regulations and standards, many countries consider the WHO Guidelines for drinking-water quality (GDWQ). To better understand the extent to which the GDWQ are used and reflected in these standards, this global review summarizes information from 104... countries and territories on values specified in national drinking-water quality standards for aesthetic, chemical, microbiological and radiological parameters.
The information provided will support regulatory agencies and other key stakeholders to access and compare data when setting or revising national drinking-water quality regulations and standards.

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.

The 2018 global health financing report presents health spending data for all WHO Member States between 2000 and 2016 based on the SHA 2011 methodology. It shows a transformation trajectory for the global spending on health, with increasing domestic public funding and declining external financing. T...his report also presents, for the first time, spending on primary health care and specific diseases and looks closely at the relationship between spending and service coverage

The Global Early Warning – Early Action (EWEA) report on food security and agriculture is developed by the Food and Agriculture Organization of the United Nations (FAO). The report is part of FAO’s EWEA system, which aims to translate forecasts and early warnings into anticipatory action.
This timely report comes at a decisive moment in history where
we can reshape urban environments and health systems for the
majority of the world’s population that live in cities. Enabling
this transformation are the SDGs, which have reconfigured how
governments and the international community... need to plan and
implement actions to eradicate poverty and inequality, create
inclusive economic growth, preserve the planet and improve
population health. Central to this quest is to create equitable,
healthier cities for sustainable development.

This report started with a simple question—“How can we tell how much funding is devoted to global health programs?”—and ended (more than two years later) with an answer that is far from simple. As those who have tried know well, tracking health-related funding is challenging in any setting, ...given the range of public and private sources and the many types of services and programs that fall within the definition of “health sector.” It is made all the more complicated when significant external support from donors and private charities plus in-kind donations of drugs and other inputs are taken into account. The task is made yet harder by inadequate public expenditure management systems in countries where public agencies’ capacity is stretched very thin and by donor accounting structures that are not designed to respond in a timely way

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 exposure 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.

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.

The STEPS survey of noncommunicable disease (NCD) risk factors in Zambia was carried out from July to September 2017. Zambia carried out Step 1, Step 2 and Step 3. Socio demographic and behavioural information was collected in Step 1. Physical measurements such as height, weight and blood pressure w...ere collected in Step 2. Biochemical measurements were collected to assess blood glucose and cholesterol levels in Step 3. The survey was a population-based survey of adults aged 18-69. A multi-stage cluster sample design was used to produce representative data for that age range in Zambia. A total of 4,302 adults participated in the survey. The overall response rate was 74% for Step 1 and 2 and 65% for Step 3. A repeat survey is planned for 2022 if funds permit.
