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.

Biodiversity and Health in the Face of Climate Change pp 47–66
This chapter reviews the emerging importance of pollen allergies in relation to ongoing climate change. Allergic diseases have been increasing in prevalence over the last decades, partly as the result of the impact of climate change. ...Increased sensitisation rates and more severe symptoms have been the partial outcome of: increased pollen production of wind-pollinated plants resulting in long-term increased abundance of pollen in the air we breathe; earlier shifts of airborne pollen seasons making occurrence of allergic symptoms harder to predict and deal with efficiently; increased allergenicity of pollen causing more severe health effects in allergic individuals; introduction of new, invasive allergenic plant species causing new sensitisations; environment-environment interactions, such as plants and hosted microorganisms, i.e. fungi and bacteria, which comprise a complex and dynamic system, with additive, presently unforeseeable influences on human health; environment-human interactions, as the consequence of a combination of environmental factors, like air pollution, global warming, urbanisation and microclimatic variability, which create a multi-resolution spatiotemporal system that requires new processing technologies and huge data inflow in order to be thoroughly investigated. We suggest that novel, real-time, personalised pollen information services, like mobile-app risk alerts, must be developed to provide the optimum first line of allergy management.

These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting

WHO today released its first roadmap to tackle postpartum haemorrhage (PPH) – defined as excessive bleeding after childbirth - which affects millions of women annually and is the world’s leading cause of maternal deaths.
Despite being preventable and treatable, PPH results in around 70 000 de...aths every year. For those who survive, it can cause disabilities and psychological trauma that last for years.
“Severe bleeding in childbirth is one of the most common causes of maternal mortality, yet it is highly preventable and treatable,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “This new roadmap charts a path forward to a world in which more women have a safe birth and a healthy future with their families.”
The Roadmap aims to help countries address stark differences in survival outcomes from PPH, which reflect major inequities in access to essential health services. Over 85% of deaths from PPH happen in sub-Saharan Africa and South Asia. Risk factors include anaemia, placental abnormalities, and other complications in pregnancy such as infections and pre-eclampsia.
Many risk factors can be managed if there is quality antenatal care, including access to ultrasound, alongside effective monitoring in the hours after birth. If bleeding starts, it also needs to be detected and treated extremely quickly. Too often, however, health facilities lack necessary healthcare workers or resources, including lifesaving commodities such as oxytocin, tranexamic acid or blood for transfusions.
“Addressing postpartum haemorrhage needs a multipronged approach focusing on both prevention and response - preventing risk factors and providing immediate access to treatments when needed - alongside broader efforts to strengthen women’s rights,” said Dr Pascale Allotey, WHO Director for Sexual and Reproductive Health and HRP, the UN’s special programme on research development and training in human reproduction. “Every woman, no matter where she lives, should have access to timely, high quality maternity care, with trained health workers, essential equipment and shelves stocked with appropriate and effective commodities – this is crucial for treating postpartum bleeding and reducing maternal deaths.”

The goal of asthma treatment is to obtain clinical control and reduce future risks to the patient. To reach this goal in children with asthma, ongoing monitoring is essential. While all components of asthma, such as symptoms, lung function, bronchial hyperresponsiveness and inflammation, may exist i...n various combinations in different individuals, to date there is limited evidence on how to integrate these for optimal monitoring of children with asthma. The aims of this ERS Task Force were to describe the current practise and give an overview of the best available evidence on how to monitor children with asthma.
22 clinical and research experts reviewed the literature. A modified Delphi method and four Task Force meetings were used to reach a consensus.
This statement summarises the literature on monitoring children with asthma. Available tools for monitoring children with asthma, such as clinical tools, lung function, bronchial responsiveness and inflammatory markers, are described as are the ways in which they may be used in children with asthma. Management-related issues, comorbidities and environmental factors are summarised.
Despite considerable interest in monitoring asthma in children, for many aspects of monitoring asthma in children there is a substantial lack of evidence.

The greatest risk to persons engaging in international medical emergency response is poor preparation.
The In Control handbook hopes to provide a remedy.
At the time of writing, we are living through the Coronavirus (COVID-19) pandemic, a health emergency that disregards physical borders, brin...gs into focus social inequalities and affects people on every continent. This shared challenge requires unprecedented measures and the collaboration of the brightest minds to support global health protection through this crisis and beyond. Healthcare infrastructures have to be strengthened, public health capacities and processes upgraded, medical countermeasures and vaccinations found and psychosocial side-effects treated.
Solidarity is the normative order of the day and the human species has to collaborate to face this invisible threat. Hiding and living in fear is not an option in this interconnected world. We have both a responsibility and an opportunity to make substantial contributions to a safer, healthier and more sustainable future for us all.
The existence of this handbook is an impressive example of solidarity. Over 50 authors from more than 15 institutes and organisations have come together voluntarily within a very short time to make their expertise available and enable cross-sectoral thinking. Knowledge is bundled, resources are combined, information gaps are filled. The In Control handbook is not a theoretical treatise of possible dangers, but a collection of subject-matter expertise, written by experts and practitioners who have shaped health topics over the past 20 years in the most diverse corners of the world.
The Centre for International Health Protection at the Robert Koch Institute (RKI) is collaborating with its partners and investing heavily in the build-up of operational know-how and capacity to support health crisis response abroad. This is done by preparing and enabling professionals to deploy safely across the world to assist those in need. In Control addresses the multi-faceted challenges of an international deployment. Readers will find not only technical medical information, but also insights into, for example, the fragility of our environment, the cultural differences that influence risk communication or the dilemmas arising from social distancing. Legal principles are highlighted, along with ethical guidance to ensure that our actions and decisions correspond to the highest moral standards.

Climate change is increasing risks to human health and to the health systems that seek to protect the safety and well-being of populations. Health authorities require information about current associatio...ns between health outcomes and weather or climate, vulnerable populations, projections of future risks and adaptation opportunities in order to reduce exposures, empower individuals to take needed protective actions and build climate-resilient health systems. An increasing number of health authorities from local to national levels seek this information by conducting climate change and health vulnerability and adaptation assessments. While assessments can provide valuable information to plan for climate change impacts, the results of many studies are not helping to build the global evidence-base of knowledge in this area. They are also often not integrated into adaptation decision making, sometimes because the health sector is not involved in climate change policy making processes at the national level. Significant barriers related to data accessibility, a limited number of climate and health models, uncertainty in climate projections, and a lack of funding and expertise, particularly in developing countries, challenge health authority efforts to conduct rigorous assessments and apply the findings. This paper examines the evolution of climate change and health vulnerability and adaptation assessments, including guidance developed for such projects, the number of assessments that have been conducted globally and implementation of the findings to support health adaptation action. Greater capacity building that facilitates assessments from local to national scales will support collaborative efforts to protect health from current climate hazards and future climate change. Health sector officials will benefit from additional resources and partnership opportunities to ensure that evidence about climate change impacts on health is effectively translated into needed actions to build health resilience.

Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases. Despite prior perception of low NCDs mortality rates, current evidence suggests t...hat SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Although ischemic heart disease (IHD) has been identified as the leading cause of CVDs mortality in SSA followed by stroke and hypertensive heart disease from statistical models, real field data suggest IHD rates are still relatively low. The neglected endemic CVDs of SSA such as endomyocardial fibrosis and rheumatic heart disease as well as congenital heart diseases remain unconquered. While the underlying aetiology of heart failure among adults in high-income countries (HIC) is IHD, in SSA the leading causes are hypertensive heart disease, cardiomyopathy, rheumatic heart disease, and congenital heart diseases. Of concern is the tendency of CVDs to occur at younger ages in SSA populations, approximately two decades earlier compared to HIC. Obstacles hampering primary and secondary prevention of CVDs in SSA include insufficient health care systems and infrastructure, scarcity of cardiac professionals, skewed budget allocation and disproportionate prioritization away from NCDs, high cost of cardiac treatments and interventions coupled with rarity of health insurance systems. This review gives an overview of the descriptive epidemiology of CVDs in SSA, while contrasting with the HIC and highlighting impediments to their management and making recommendations.

Cryptococcal disease is one of the most common opportunistic infections among people living with advanced HIV disease and is a major contributor to severe illness, morbidity, and mortality, particularly in sub-Saharan Africa.
These guidelines update the recommendations that were first released i...n 2018 on diagnosing, preventing, and managing cryptococcal disease. In response to important new evidence that became available in 2021, these new guidelines strongly recommend a single high dose of liposomal amphotericin B as part of the preferred induction regimen for the treatment of cryptococcal meningitis in people living with HIV. This simplified regimen - a single high dose of liposomal amphotericin B paired with other standard medicines (flucytosine and fluconazole) - is as effective as the previous WHO standard of care, with the benefits of lower toxicity and fewer monitoring demands.
The objective of these guidelines is to provide updated, evidence-informed recommendations for treating adults, adolescents and children living with HIV who have cryptococcal disease. These guidelines are aimed at HIV programme managers, policymakers, national treatment advisory boards, implementing partners and health-care professionals providing care for people living with HIV in resource-limited settings with a high burden of cryptococcal disease.

Community-based strategies play a significant role in many health systems in low- and middle-income countries, especially in light of critical shortages in the health workforce. The term community health worker has been used to refer to volunteers and salaried, professional or lay health workers wit...h a wide range of training, experience, scope of practice and integration in health systems. In the context of this study, we use the term community-based practitioner (CBPs) to reflect the diverse nature of these cadres of health workers.
CBPs provide preventive, promotive, curative and palliative services across a range of areas, including reproductive, maternal, newborn and child health, HIV, tuberculosis, malaria, control of other endemic diseases, and noncommunicable diseases. Significant evidence has emerged over the past two decades on their effectiveness, which has triggered interest in the potential to use their services to expand access to care, in particular in rural and underserved areas where deployment and retention of more qualified health workers is problematic. Calls have been made to integrate CBP programmes in human resources and health strategies, and to scale up rapidly the extent and coverage of CBP initiatives.

One approach to development assistance for health, or health aid, emphasizes the ex ante selection of cost-effective health interventions, an approach that began with the World Development Report (1993) on Investing in Health and has since been adopted by the Effective Altruism community. But just h...ow much of health aid is cost-effective? In this paper, we examine projects in the Organisation for Economic Co-operation and Development (OECD) Creditor Reporting System, the standard dataset that measures and characterizes development assistance for health, for the
years 2019 to 2021, and count the number of projects that refer to interventions from a list of highly cost-effective interventions as defined by the Disease Control Priorities Project, third edition. This exploratory quantitative analysis indicates that 61% of projects used a key word/phrase of a costeffective intervention. There were 11.9 interventions mapped per project on average. There is little evidence that donors tailor the set of interventions to country income levels by cost-effectiveness.
Policymakers may benefit from reviewing the full portfolio of interventions covered by domestic and external resources.

The Malaria Ministerial Conference, co-hosted by WHO and the Government of Cameroon on 6 March 2024, brought together more than 400 stakeholders, including Ministers of Health and senior representatives from the African countries hardest hit by malaria, global health leaders, scientists, civil socie...ty and other partners. The pivotal meeting sought to leverage political commitment, scientific innovation and community engagement to reshape the trajectory of malaria control in high burden African countries, and beyond.
At the end of the meeting and in the weeks that followed, Ministers of Health from the 11 “High Burden High Impact” African countries (Burkina Faso, Cameroon, Democratic Republic of the Congo, Ghana, Mali, Mozambique, Niger, Nigeria, Sudan, Uganda and United Republic of Tanzania) signed the Yaoundé Declaration, pledging their “unwavering commitment” to the principle that “no one should die from malaria given the tools and systems available.” Success in reducing malaria morbidity and mortality will hinge on efforts by countries to translate this political commitment into actions and resources that will save lives.

Addressing comorbidities and risk factors for tuberculosis (TB) is a crucial component of the World Health Organization (WHO)’s End TB Strategy. This WHO operational handbook on tuberculosis. Module 6: tuberculosis and comorbidities aims to support countries in scaling up people-centred care, base...d on the latest WHO recommendations on TB and key comorbidities, and drawing upon additional evidence, best practices and inputs from various experts and stakeholders obtained during WHO processes. It is intended for use by people working in ministries of health, particularly TB programmes and the relevant departments or programmes responsible for comorbidities and health-related risk factors for TB such as HIV, diabetes, undernutrition, substance use, and tobacco use, as well as programmes addressing mental health and lung health. This operational handbook is a living document and will include a separate section for each of the key TB comorbidities or health-related risk factors. The third edition includes guidance for HIV-associated TB, mental health conditions and diabetes, which are three conditions strongly associated with TB and which result in higher mortality, poorer TB treatment outcomes and negatively impact health-related quality of life. The operational handbook aims to facilitate early detection, proper assessment and adequate management of people affected by TB and comorbidities. Full implementation of this guidance is expected to have a significant impact on TB treatment outcomes and health-related quality of life for people affected by TB.

Beat the heat: child health amid heatwaves in Europe and Central Asia finds that half of these children died from heat-related illnesses in their first year of life. Most children died during the summer months.
"Around half of children across Europe and Central Asia – or 92 million children –... are already exposed to frequent heatwaves in a region where temperatures are rising at the fastest rate globally. The increasingly high temperatures can have serious health complications for children, especially the youngest children, even in a short space of time. Without care, these complications can be life-threatening,” said Regina De Dominicis UNICEF Regional Director for Europe and Central Asia.
Heat exposure has acute effects on children, even before they are born, and can result in pre-term births, low birth weight, stillbirth, and congenital anomalies. Heat stress is a direct cause of infant mortality, can affect infant growth and cause a range of paediatric diseases. The report also notes that extreme heat caused the loss of more than 32,000 years of healthy life among children and teenagers in the region.
As the temperatures continue to rise, UNICEF urges governments across Europe and Central Asia to:
- Integrate strategies to reduce the impact of heatwaves including through National Determined Contributions (NDC), National Adaptation Plans (NAP), and disaster risk reduction and disaster management policies with children at the centre of these plans
Invest in heat health action plans and primary health care to more adequately support heat-related illness among children
- Invest in early warning systems, including heat alert systems
- Adapt education facilities to reduce the temperatures in the areas children play in and equip teachers with skills to respond to heat stress
- Adapt urban design and infrastructure including ensuring buildings, particularly those housing the most vulnerable communities are equipped to minimize heat exposure
- Secure the provision of safe water, particularly in countries with deteriorating water quality and availability.
UNICEF works with governments, partners and communities across the region to build resilience against heatwaves. This includes equipping teachers, community health workers and families with the skills and knowledge to respond to heat stress.

Little is known about asthma control in the rising number of African children who suffer from this condition. The Achieving Control of Asthma in Children in Africa (ACACIA) study is an observational study collecting evidence about paediatric asthma in urban areas of Ghana, Malawi, Nigeria, South Afr...ica, Uganda and Zimbabwe. The primary objectives are: (1) to identify 3000 children aged between 12 years and 14 years with asthma symptoms; and (2) to assess their asthma control, current treatment, knowledge of and attitudes to asthma and barriers to achieving good control. Secondary objective is to develop interventions addressing identified barriers to good symptom control.
Each centre will undertake screening to identify 500 school children with asthma symptoms using questions from the Global Asthma Network’s questionnaire. Children identified to have asthma symptoms will fill in a digital survey, including: Asthma Control Test, questions on medication usage and adherence, medical care, the Brief-Illness Perception questionnaire and environmental factors. Exhaled nitric oxide testing and prebronchodilator and postbronchodilator spirometry will be performed. A subgroup of children will participate in focus group discussions. Results will be analysed using descriptive statistics and comparative analysis. Informed by these results, we will assess the feasibility of potential interventions, including the adaption of a UK-based theatre performance about asthma attitudes and digital solutions to improve asthma management.

Against the backdrop of the COVID-19 pandemic, health is receiving unprecedented public and political attention. Yet the fact that climate change also presents us with a health crisis deserves further recognition. From more deaths due to heat stress to increased transmission of infectious diseases, ...climate change affects the social and environmental determinants of health in ways that are profound and far-reaching. The fundamental interdependency of human health and the health of the environment is encapsulated in the concept of planetary health, a scientific field and social movement that has been gaining force since the 2015 publication of the Rockefeller Foundation-Lancet Commission report “Safeguarding human health in the Anthropocene epoch”.
We see an urgent need for strategic communication to raise awareness of climate-health synergies in order to overcome the misperception that climate and health are two independent agendas. The fragmented and sector-focused nature of thinking and action remains a significant barrier to integrating health considerations into climate planning and project development. Inevitably, collaboration across sectors requires a community of practice. Despite recent efforts focused on the climate-health nexus, much work remains to be done to translate scientific findings for policymakers, mobilise climate financing resources in support of health co-benefits, and promote genderjust solutions within climate change projects.

Cognitive deficits in schizophrenia can massively impact functionality and quality of life, furthering the importance of cognitive training. Despite the development of the field in Europe and in the United States, no programmes have been developed and tested in developing countries. Different cultur...al backgrounds, budget restrictions, and other difficulties may render treatment packages created in high income countries difficult for adoption by developing nations. We performed a pilot double-blind, randomized, controlled trial in order to investigate the efficacy and feasibility of an attention and memory training programme specially created in
a developing nation. The intervention used simple, widely available materials, required minimal infrastructure, and was conducted in groups.The sample included seventeen stable Brazilians with schizophrenia. Sessions were conducted weekly during five months. The cognitive training group showed significant improvements in inhibitory control and set-shifting over time. Both groups showed improvements in symptoms, processing speed, selective attention, executive function, and long-term visual memory. Improvements were found in the control group in long-term verbal memory and concentration. Our findings reinforce the idea that cognitive training in schizophrenia can be constructed using simple resources and infrastructure, facilitating its adoption by developing countries, and it may improve cognition.

The Government of Malawi’s Health Sector Strategic Plan II highlights the importance of service integration; however, in practice, this has not been fully realized. We conducted a mixed methods evaluation of efforts to systematically implement integrated family planning and immunization services i...n all health facilities and associated community sites in Ntchisi and Dowa districts during June 2016–September 2017. Methods included secondary analysis of service statistics (pre- and postintervention), focus group discussions with mothers and fathers of children under age one, and in-depth interviews with service providers, supervisors, and managers. Results indicate statistically significant increases in family planning users and shifts in use of family planning services from health facilities to community sites. The intervention had no effect on immunization doses administered or dropout rates. According to mothers and fathers, benefits of service integration included time savings, convenience, and improved understanding of services. Provision and use of integrated services were affected by availability of human resources and commodities, community linkages, data collection procedures and availability, sociocultural barriers, organization of services, and supervision and commitment of health surveillance assistants. The integration approach was perceived to be feasible and beneficial by clients and providers.
