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.

This practical guideline establishes definitions for “contact”, “contact person”, “contact tracing” and other associated concepts. It allows for improvement of contact tracing strategies and provides recommendations attempting to answer some, though not all, questions that arose during t...he 2019 coronavirus pandemic and other outbreaks. The use of this guideline begins once people have been diagnosed and the potential for transmission exists. It is not, however, intended to assist with case investigation. The guideline empowers health workers, governments, and public health officials with the tools to implement effective contact tracing strategies.

This checklist is for any organization or person supporting the routine use of evidence in
the process of policy-making. Evidence-informed policy-making (EIPM) is essential for achieving the Sustainable Development Goals (SDGs) and universal health coverage (UHC). Its importance is emphasized in WH...O’s Thirteenth General Programme of
Work 2019–2023 (GPW13). This checklist was developed by the WHO Secretariat of Evidence-Informed Policy Network (EVIPNet) to assist its Member countries in institutionalizing EIPM. Government agencies (i.e. the staff of the Ministry of Health),
knowledge intermediaries and researchers focused on strengthening EIPM will find in this checklist some key steps and tools to help their work. While the health sector is a key target group for EVIPNet, this tool can be applied by stakeholders from
different social sectors

This companion to the ALNAP EHA Guide offers protection-specific insights for evaluators and evaluation commissioners across the humanitarian sector. It covers the planning, data management and analysis phases of evaluation and addresses a range of challenges that – whilst not all unique to protec...tion – are often exacerbated by the contexts in which protection activities typically take place. Challenges addressed include those arising from the multi-faceted nature of protection activities, the difficulty understanding cause-effect relationships underlying protection risks, and the challenges of accessing and managing very sensitive data, sometimes drawn from communities in conflict.

Organizing and Delivering High Quality Care for Chronic Noncommunicable Diseases in the Americas
Using the WHO model list of essential medicines to update a national essential medicines list
Since 1977, WHO has been working with countries to design the package of essential medicines as an integral component of treatment within the continuum of care, developing and disseminating the Model List ...of Essential Medicines (Model List). WHO is committed to supporting Member States in sharing best practices in selecting
essential medicines, and in developing processes for the selection of medicines for national essential medicines lists (national EMLs, or NEMLs) consistent with the evidence-based methods used for updating the WHO Model List.

Safe sanitation is essential for health, from preventing infections to improving and maintaining mental and social
well-being. Lack of adequate sanitation contributes to diarrhoeal diseases, parasitic infections, and undernutrition, as
well as posing significant risks and causing anxiety, especial...ly for women and girls. Achieving universal access to safe
sanitation, which protects health, privacy, and dignity, is a global development goal and a recognized basic human right.

Bonchial asthma is the most common chronic respiratory disease in the world. In Kenya, it has been estimated that about 7.5% of the Kenyan population, nearly 4 million people, are currently living with asthma. Many cases tend to be underdiagnosed and undertreated which leads to high levels of morbid...ity and avoidable deaths. The consequences of poorly controlled asthma, including physical, mental, social, and economic impacts, are magnified in the poor on account of poor access to asthma services and sub-optimal quality of those services. With these guidelines, Kenya's Ministry of Health aims to work towards embedding asthma care in Universal Health Care (UHC) to ensure that quality asthma services are available in primary care settings with
referral networks strengthened for those who may require secondary and tertiary care. These national asthma guidelines will also ensure that treatment for asthma is standardized in both the public and the non-state health care sector.

National action plans on antimicrobial resistance (AMR) often overlook the critical intersection of gender, despite evidence that exposure and susceptibility to infection, health-seeking behaviours, as well as antimicrobial prescribing and use patterns are all influenced by gender.
WHO has published the first-ever guidance on the clinical management of diphtheria. The only previously available guidance was an operational protocol. The new guidance followed the rigorous process for developing guidance at WHO.
It addresses the use of Diphtheria Antitoxin (DAT) in the treatmen...t of diphtheria. There is a worldwide shortage of DAT and evidence based recommendations on the use of DAT were requested by many Member States.
The guidance also includes new recommendations on antibiotics. In patients with suspected or confirmed diphtheria, WHO recommends using macrolide antibiotics (azithromycin, erythromycin) rather than penicillin antibiotics.
This clinical practice guideline has been rapidly developed recognizing the global increase in diphtheria outbreaks. Outbreaks of diphtheria in Nigeria, Guinea and neighbouring countries in 2023 have highlighted the urgent need for evidence-based clinical practice guidelines for the treatment of diphtheria. Given the sporadic nature of outbreaks, many clinicians in the affected regions have never managed acute diphtheria and its related complications. Diphtheria remains a neglected disease and vaccination is the top priority. At the same time, for patients with diphtheria, access to antibiotics, DAT and supportive care can be lifesaving.

The environment in which young people live, learn and play significantly affects their decisions about whether to consume alcohol. Environmental factors are the main risk factors driving alcohol consumption and related harm among young people. Environments that normalize alcohol consumption – term...ed alcogenic environments – include contexts with unregulated advertising and marketing of alcoholic beverages, higher alcohol outlet density, products designed to facilitate affordability and low prices of alcoholic beverages. A recent body of research evidence has emerged related to the measurement, functional significance and consequences of living in alcogenic environments. This includes findings on the complex and bidirectional interactions among alcohol acceptability, availability and affordability and how they create and perpetuate alcogenic environments. Comprehensive and enforced alcohol control policies are effective at delaying the age of onset and lowering alcohol prevalence and frequency among young people. Evidence consistently confirms the effectiveness of designing and implementing alcohol control policies that regulate upstream the drivers of alcogenic environment, including alcohol availability, acceptability and affordability. These policies need to be multipronged and address the complex interactions between these drivers and the local alcohol culture

The waves of yellow fever transmission in the Region of the Americas in 2016–2018 involved the largest number of human and epizootic cases to be reported in several decades. Yellow fever is a serious viral hemorrhagic disease that poses a challenge for health professionals. It requires early recog...nition of signs and symptoms, which are often nonspecific, and it can mimic other acute febrile syndromes. Early detection of suspected or confirmed cases, monitoring of vital signs, life support measures, and treatment of acute kidney failure continue to be the recommended strategies for case management. This report is the result of discussions among experienced specialists in the Americas on the clinical management of yellow fever patients, especially during outbreaks and epidemics, in the context of current medical and scientific evidence and taking into account the technical guidelines already available in the countries of the Region. It includes flowcharts for initially addressing patients with clinical suspicion of yellow fever and proposes a minimum package of laboratory tests that may be useful in contexts where resources are limited. In addition, it considers aspects of health system organization for dealing with yellow fever outbreaks and epidemics.
