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.

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality.
Without rapid interventions, data estimates show a major increase in cancer mo...rtality from 520 348 in 2020 to about
1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of
analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the
region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national
cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as
HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive,
and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed
by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial
investment is needed in developing cancer registries and cancer diagnostics for core cancer tests.

In order to understand if the COVID-19 pandemic has impacted food availability and access at markets in Cambodia, the World Food Programme (WFP) monitors the retail and wholesale prices of key food commodities (see Annex 1 and 2) in 45 urban and rural markets across the country (see the Methods sect...ion for more details). An average of 340 traders and market chiefs are interviewed every two weeks, through a call center contracted by WFP. In addition to prices, market chiefs are also interviewed to assess market functionality, including supply and demand issues. Additional information is used to interpret the results and understand the broader context.

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.

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.

The purpose of this guidance is to assist WHO Member States, and other stakeholders, in the establishment and development of programmes of integrated surveillance of antimicrobial resistance in foodborne bacteria (i.e., bacteria commonly transmitted by food). In this guidance, “integrated surveill...ance of antimicrobial resistance in foodborne bacteria” is defined as the collection, validation, analyses and reporting of relevant microbiological and epidemiological data on antimicrobial resistance in foodborne bacteria from humans, animals, and food, and on relevant antimicrobial use in humans and animals. Integrated surveillance of antimicrobial resistance in foodborne bacteria therefore includes data from relevant food chain sectors (animals, food and humans) and includes data on both antimicrobial resistance and antimicrobial use. Integrated surveillance of antimicrobial resistance for foodborne bacteria expands on traditional public health surveillance to include multiple elements of the food chain, and to include antimicrobial use data, to better understand the sources of infection and transmission routes.

Ethiopia has seen high economic growth over the last decade, but remains a poor country with a high burden of disease. It has made considerable health gains in recent years, mainly by having health policies that focus on extending primary healthcare, using health extension workers. It... has made good use of existing resources,but has a low health expenditure (of around US$21 per capita, and totalling 4per centof GDP). It has a federal system with devolved healthcare financing, whereby block grants are allocated to sectors at regional and woreda(district) level. The challenge now,with the epidemiological transition (and a sense that the ‘low-hanging fruits’have already been gathered in relation to public health), is how Ethiopia, still poor, continuesto invest in health improvements?Human resources for health (HRH) are a critical pillar within any health system –the health staff combine inputs to provide the services, thus affecting how all other resources are used, and they make frontline (and back-office) decisions thatare importantdeterminants of servicequality,effectiveness and equity. HRH is usually the most resource-intensive element within the health system –commonly absorbing 50–70per centof public expenditure onhealth, although the proportions are very varied by individual countries and across regions. As they are commonly part of the public administration, reforms to HRH are also part of a complex political economy in most countries.Assessing value for money (VfM) in relation to HRH is correspondingly complex;across the value chain, manyfactors influence the conversion of inputs into outputs and outcomes (see Figure 1).A more detailed description of the HRH value chain can be found in Annex1.

Drugs and medical supplies are dispensed at the cutting edge level of the interface between the public health system and the people. Availability or lack of it brings either credit or discredit to the public health system. The primary reason for holding stocks of medicines and medical supplies in a ...proper scientific manner is to ensure continuous and uninterrupted availability to prevent stock-outs, especially of critical items of supply while at the same time ensuring that stocks of medicines do not get expired. An efficient inventory management is a pre-requisite for optimal stock management. It enables the management of health facilities to know the current pattern of consumption of drug trends over a period of time and also variances. The environmental control of the drugs and other medical supplies play an important role to keep the products' efficacy intact. Some medicines and vaccines need special storage temperature, otherwise, there may be wastage. The quality of the medicines can be adversely affected by poor storage, transportation and distribution. Thus, maintaining proper storage condition for health commodities is vital for ensuring their quality. So, by this training, CDMU wants to educate different people dealing with medicines and equip them for the roles they have to perform efficiently so that the wastage does not take place or can be minimized.

The World Heart Federation (WHF) Roadmap series covers a large range of cardiovascular conditions. These Roadmaps identify potential roadblocks and their solutions to improve the prevention, detection and management of cardiovascular diseases and provide a generic global framework available for loca...l adaptation. A first Roadmap on raised blood pressure was published in 2015. Since then, advances in hypertension have included the publication of new clinical guidelines (AHA/ACC; ESC; ESH/ISH); the launch of the WHO Global HEARTS Initiative in 2016 and the associated Resolve to Save Lives (RTSL) initiative in 2017; the inclusion of single-pill combinations on the WHO Essential
Medicines’ list as well as various advances in technology, in particular telemedicine and mobile health. Given the substantial benefit accrued from effective interventions in the management of hypertension and their potential for scalability in low and middle-income countries (LMICs), the WHF has now revisited and updated the ‘Roadmap for raised BP’ as ‘Roadmap for hypertension’
by incorporating new developments in science and policy. Even though cost-effective lifestyle and medical interventions to prevent and manage hypertension exist, uptake is still low, particularly in resource-poor areas. This Roadmap examined the roadblocks pertaining to both the demand side (demographic and socio-economic factors, knowledge and beliefs, social relations, norms, and
traditions) and the supply side (health systems resources and processes) along the patient pathway to propose a range of possible solutions to overcoming them. Those include the development of population-wide prevention and control programmes; the implementation of opportunistic screening and of out-of-office blood pressure measurements; the strengthening of primary care and a greater focus on task sharing and team-based care; the delivery of people-centred care and stronger patient and carer education; and the facilitation of adherence to treatment. All of the above are dependent upon the availability and effective distribution of good quality, evidencebased, inexpensive BP-lowering agents.

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.

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.

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.
Clin Microbiol Infect 2011;17(Suppl. 6): 1–24 The full version of these guidelines can be found on Wiley Online Library.

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.

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.
