Examples of small-scale disinfection products for safe drinking water
6th edition, 2010. | Published in collaboration with World Health Organisation and Clinton Health Access Initiative.
Using an ensemble of climate models and socioeconomic scenarios, WRI scored and ranked future water stress—a measure of competition and depletion of surface water—in 167 countries by 2020, 2030, and 2040. We found that 33 countries face extremely high water stress in 2040 (see the full list). We... also found that Chile, Estonia, Namibia, and Botswana could face an especially significant increase in water stress by 2040. This means that businesses, farms, and communities in these countries in particular may be more vulnerable to scarcity than they are today.

The guidelines are to be used to guide the management of adults with lower respiratory tract infection (LRTI). As will be seen in the following text, this diagnosis, and the other clinical syndromes within this grouping, can be difficult to make accurately. In the absence of agreed definitions of th...ese syndromes these guidelines are to be used when, in the opinion of a clinician, an LRTI syndrome is present. The following are put forward as def-initions to guide the clinician, but it will be seen in the ensuingtext that some of these labels will always be inaccurate. These definitions are pragmatic and based on a synthesis of available studies. They are primarily meant to be simple to apply in clinical practice, and this might be at the expense of scientific accuracy. These definitions are not mutually exclusive, with lower respiratory tract infection being an umbrella term that includes all others, which can also be used for cases that cannot be classified into one of the other groups. No new evidence has been identified that would lead to a change in the clinical definitions,which are therefore unchanged from the 2005 publication.

This second edition of the “living paper” contributes to the global knowledge on how countries are responding to the pandemic by documenting real-time actions in a key area of response – that is, social protection measures planned or implemented by governments.
For the purpose of this revie...w, we organized interventions by social assistance, social insurance and labor market programs. For the latter measures, we deliberately focused on supply-side programs (e.g., mostly wage subsidies and other activation programs). In most cases, data sources include official information published in government websites, while in many cases we reported information from global and national news outlets. In some cases, information was provided directly by country-based experts, while the full database was validated and integrated by regional and country social protection teams at the World Bank. Overall, findings should be considered preliminary and interpreted with caution.

This guidance note on Syria is the first in a series of comprehensive Q&As, which aims to give practical guidance on how to comply with EU sanctions when providing humanitarian aid, in particular medical assistance, to fight the coronavirus pandemic. By clarifying the responsibilities and processes ...for the provision of this aid, this note should facilitate the task of humanitarian operators in Syria. It should speed up the channelling of equipment and assistance to fight the coronavirus pandemic in Syria. It is addressed to all actors involved in the supply of humanitarian aid, such as the competent authorities of EU Member States, which manage the implementation of EU sanctions, and public and private operators (donors, NGOs, banks and other actors involved in humanitarian activities), which must comply with EU sanctions when providing assistance.

Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

Atlas of African Health Statistics 2022: Health situation analysis of the WHO African Region
Since 2019, we have been implementing Phase 2 of the regional Transformation Agenda, which informs and aligns with the global WHO Transformation, to ensure WHO is accountable, driven by re- sults and provid...ing value for money in the pursuit of better health. Our global priority in this period is to contribute to delivering on the triple billion targets of expanding universal health coverage, protecting people from emergencies, and promoting health and well-being for people across the Region.
This year’s Atlas of African Health Statistics is being produced in the context of the COVID-19 pandemic that we have been expe- riencing for over two years. The ongoing coronavirus pandemic, together with other health emergencies in the WHO African Re- gion, is yet again testing the strength and resilience of our health systems. Indeed, the impact of COVID-19 is visible in the disruption of services. The report also presents the latest data for more than 50 health-related indicators of the Sustainable Development Goals and WHO’s “triple billion” targets and provides comprehensive country-level statistics using the results chain of the AFRO frame- work of actions for strengthening health systems to achieve UHC and the health-related SDGs.

Access to safe blood and blood products is recognized as one of the key requirements for delivery of modern health care in the journey towards health for all. The foundation of safe and sustainable blood supplies depends on the collection of blood from voluntary non-remunerated and low-risk donors. ...Data from the WHO Global Database for Blood Safety (GDBS) brings out several inadequacies related to the supply and safety of blood and blood products. These inadequacies include a number of variations in safe blood practices across the world, including the quantity of blood donated (voluntary and replacement types), quality and adequate testing of the donated blood (immunohaematology [IH] and transfusion-transmitted infections [TTIs]), rational use of blood and blood components such as appropriate patient blood management protocols. These variations are very high in countries of the South-East Asian Region and most of them are either low- or middle-income countries (LMICs).

Cholera is a transmissible diarrhoeal infection caused by Vibrio cholerae. Endemic and/or epidemic in over 40 countries (mainly in Africa and Asia), cholera continues to be a major global public health issue.
The World Health Organization (WHO) estimates that the number of cases reported worldwid...e represents in reality only 5 to 10% of actual cases.
This guide is intended for medical and non-medical staff responding to a cholera outbreak. It attempts to provide concrete answers to the questions and problems faced by staff, based on the recommendations of reference organisations, such as WHO and UNICEF, as well as Médecins Sans Frontières’ experience in the field.
It is divided into 8 chapters. Chapter 1, Cholera overview, outlines the epidemiological and clinical features of cholera. Chapter 2, Outbreak investigation, explains the method and stages of a field investigation, from the alert to implementation of initial activities. Chapter 3, Cholera control measures, details measures and tools to prevent and/or control cholera transmission and mortality in populations affected, or at risk of being affected, by an epidemic (curative care, prevention means and health promotion activities). Chapter 4, Strategies for epidemic response, addresses the roll-out strategies of the measures described in Chapter 3 which depend on context (e.g. urban, rural, endemic, non-endemic setting, etc.), resources and particular constraints. Chapter 5, Cholera case management, details the different stages of cholera treatment, from diagnosis through to cure.
Chapter 6, Setting up cholera treatment facilities, focuses on the installation of treatment facilities that vary in size and complexity according to operational requirements (treatment centres and units and oral rehydration points). Chapter 7, Organisation of cholera treatment facilities, describes the organisation of these specialized facilities in terms of human resources, supply, water, hygiene and sanitation, etc. Chapter 8, Monitoring and evaluation, presents the key data to be collected and analysed during an epidemic to facilitate a tailored response and evaluate its quality and effectiveness.
The guide includes various practical tools in the appendices to facilitate activities (e.g. water quality tests, job descriptions, documents, etc.). Moreover, the toolbox also contains additional tools in editable formats (individual patient file, cholera case register, pictograms).
Despite all efforts, it is possible that certain errors may have been overlooked in this guide. Please inform the authors of any errors detected.
To ensure that this guide continues to evolve while remaining adapted to field realities, please send any comments or suggestions.

Small drinking-water supplies commonly experience operational, managerial, technical and resourcing challenges that impact their ability to deliver safe and reliable services. The needs and opportunities associated with these supplies therefore warrant explicit consideration in policies and regulati...ons.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.
