This technical brief presents the current options for safe storage and point of use water treatment. It is intended to help field staff working in a variety of locations to decide upon the most appropriate course of action for providing safe water for the communities in which they work. The effectiv...eness of household water treatment options now and in the future rely to a huge extent on user compliance; it is critical that users are involved in the decision making process, and are aware of the purpose, how to use, maintain and manage their household water options. The brief therefore details relevant hygiene promotion steps for the different treatment options.

This paper has been prepared to inform discussion at the conference “Beating the DRUM - Domestic Resource Use and Mobilization for accelerating progress towards SDG3,”. Many countries face critical shortfalls in domestic resource use and mobilization (DRUM) for health, threatening to push health... goals out of reach. DRUM failures weaken human capital formation, a vital input to economic growth. Countries need more and better health spending. The first step is to apply already-proven DRUM solutions, adapting them to new contexts. However, in many countries, even the best achievable DRUM performance will not be enough. New solutions are needed, including private-sector engagement and a next generation of DAH. The “Beating the DRUM” conference offers a platform for countries and partners to dialogue and build joint strategy. While each country’s situation is unique, shared lines of action are emerging.

To assess the impact of the COVID-19 pandemic on health and HIV expenditure, UNAIDS carried out a modelling study on fiscal space for health and HIV. From a sample of 28 countries, three countries—the Democratic Republic of the Congo, Jamaica, and Lesotho—were selected to capture health and HIV ...expenditure impacts across countries with especially marked differences in burdens of disease (including HIV prevalence), HIV donor dependency, level of economic development, and geographic location. While the three-country sample is too small to permit findings to be generalized to other countries, these analyses are useful for informing UNAIDS’ work to identify some policy positions to minimize the COVID-19 pandemic’s impact on the HIV response.

Atherosclerotic lower-extremity peripheral artery disease (PAD) is increasingly recognized as an important cause of cardiovascular morbidity and mortality that affects more than 230 million people worldwide. Traditional cardiovascular risk factors, including advanced age, smoking, and diabetes, are ...strongly linked to an increase risk of PAD. Although PAD has been historically underappreciated compared to coronary artery disease and stroke, greater attention on PAD in recent years has led to important new epidemiologic insights in the areas of thrombosis, inflammation, dyslipidemia, and microvascular disease. In addition, the concept of polyvascular disease, or clinically-evident atherosclerosis in multiple arterial beds, is increasingly identified as a particularly malignant cardiovascular disease worthy of special clinical attention and further study. It is noteworthy that PAD may increase the risk of adverse outcomes in similar or even greater magnitude than coronary disease or stroke. In this review, we highlight important new advances in the epidemiology of PAD with a particular focus on polyvascular disease, emerging biomarkers, and differential risk pathways for PAD compared to other atherosclerotic diseases.

Introduction Community health workers (CHWs) are increasingly being tasked to prevent and manage cardiovascular disease (CVD) and its risk factors in underserved populations in low-income and middle-income countries (LMICs); however, little is known about the required training necessary for them to ...accomplish their role. This review aimed to evaluate the training of CHWs for the prevention and management of CVD and its risk factors in LMICs.
Methods A search strategy was developed in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and five electronic databases (Medline, Global Health, ERIC, EMBASE and CINAHL) were searched to identify peer-reviewed studies published until December 2016 on the training of CHWs for prevention or control of CVD and its risk factors in LMICs. Study characteristics were extracted using a Microsoft Excel spreadsheet and quality assessed using Effective Public Health Practice Project’s Quality Assessment Tool. The search, data extraction and quality assessment were performed independently by two researchers.
Results The search generated 928 articles of which 8 were included in the review. One study was a randomised controlled trial, while the remaining were before–after intervention studies. The training methods included classroom lectures, interactive lessons, e-learning and online support and group discussions or a mix of two or more. All the studies showed improved knowledge level post-training, and two studies demonstrated knowledge retention 6 months after the intervention.
Conclusion The results of the eight included studies suggest that CHWs can be trained effectively for CVD prevention and management. However, the effectiveness of CHW trainings would likely vary depending on context given the differences between studies (eg, CHW demographics, settings and training programmes) and the weak quality of six of the eight studies. Well-conducted mixed-methods studies are needed to provide reliable evidence about the effectiveness and cost-effectiveness of training programmes for CHWs.

In this version of the compendium, each guidance is coded using the International Classification of Health Interventions (ICHI).
The compendium provides a systematic compilation of published guidance from WHO and other UN organizations on health and environment. Guidance on policies and actions a...s well as awareness raising and capacity building interventions is presented for all major areas of health and environment. Guidance referring to priority settings for action such as cities and other urban settlements, housing, workplaces and health care facilities is also listed. For greater practical relevance, each guidance is classified according to principally involved sectors, level of implementation and instruments for implementation.
The compilation of guidance for each area of health and environment or priority setting for action is accompanied, as available, by information on main sources, exposure assessment and existing guideline values. Important tools and further resources are presented alongside.
This compilation of published guidance on health and environment highlights that a large number of actions across main topics of health and environment, concerning various sectors, and applicable to various levels are available to improve health and reduce environmental risks. This compendium is intended to serve as a repository and easy-to-use and useful resource for decision and policy makers in health and environment at various levels.

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.

Background
Low- and middle-income countries now experience the highest prevalence and mortality rates of cardiovascular disease.
Main text
While improving the availability and delivery of proven, effective therapies will no doubt mitigate this burden, we posit that studies evaluating cardiovasc...ular disease risk factors, management strategies and service delivery, in diverse settings and diverse populations, are equally critical to improving outcomes in low- and middle-income countries. Focusing on examples drawn from four cardiovascular diseases — coronary artery disease, stroke, diabetes and kidney disease — we argue that ethnicity, culture and context matter in determining the risk factors for disease as well as the comparative effectiveness of medications and other interventions, particularly diet and lifestyle interventions.
Conclusion
We believe that a host of cohort studies and randomized control trials currently being conducted or planned in low- and middle-income countries, focusing on previously understudied race/ethnic groups, have the potential to increase knowledge about the cause(s) and management of cardiovascular diseases across the world.

Cardiovascular diseases (CVDs) are a growing public health problem in Ghana and other African countries. Strokes and other CVDs have become a leading cause of death due to increasing risk factors such as hypertension. According to the Global Burden of Disease study (GBD), ischaemic heart disease was... the fourth leading cause of death in Ghana in 2016. The prevalence of hyper-
tension, a major risk factor for CVDs, is increasing rapidly and ranges from 19% to 48%, according to the Ghana Health Service Annual Report, 2017, due to rising life expectancy and the increasing prevalence of contributing factors such as overweight/obesity. Early diagnosis and adequate management of the risk factors can reduce the fatal consequences of CVDs.
At the heart of improving risk assessment and management of CVDs are nationally approved guidelines, which facilitate standardisation of care approaches.
These guidelines developed by experts from all levels of health care and stakeholders capture all recommended approaches and necessary information for clinicians and other healthcare workers on CVDs. They also serve as a practical guide for assessing and managing the most important CVDs prevalent in Ghana and can be used at all levels of care namely health facilities without a doctor; with a general practitioner and with a physician specialist.

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continue...s to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi’s community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health
service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi’s strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and
the community health team. Our analysis identified key challenges that may impede the strategy’s implementation:
(1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs
from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs’ expected duties and interactions with paid CHT personnel is recommended.
