A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

The Fifty-first World Health Assembly adopted resolution WHA51.11 in 1998, which targets the
global elimination of trachoma as a public health problem by 2020 (1). The strategy recommended
to achieve that goal is encapsulated by the acronym “SAFE”, which represents: Surgery for
individuals wi...th trachomatous trichiasis (TT; the late blinding stage of trachoma); and Antibiotics,
Facial cleanliness and Environmental improvement (2). The A, F and E interventions are delivered to
entire districts in which active (inflammatory) trachoma is common in order to treat ocular infection
with Chlamydia trachomatis, the causative organism of trachoma, and sustainably reduce its
transmission.

En 1998, la Cinquante-et-Unième Assemblée mondiale de la Santé a adopté la résolution
WHA51.11 qui vise l’élimination mondiale du trachome en tant que problème de santé publique
à l’horizon 2020 (1). La stratégie recommandée pour atteindre cet objectif est récapitulée dans
le sig...le « CHANCE » qui signifie CHirurgie pour les personnes atteintes de trichiasis
trachomateux (TT – le dernier stade cécitant du trachome) ; Antibiothérapie, Nettoyage du
visage et Changements Environnementaux (2). Les interventions relatives aux volets A, N et CE
sont menées dans des districts entiers dans lesquels les cas de trachome évolutif
(inflammatoire) sont courants, dans le but de traiter les infections oculaires dues à Chlamydia
trachomatis, l’agent pathogène à l’origine du trachome, et de réduire durablement sa
transmission.

It is impossible to address the many complex needs of respiratory virus surveillance with a single surveillance system. Multiple systems, investigations and studies must each be fit-for-purpose to specific priority surveillance objectives, and only together can they provide essential information to ...policy-makers. In essence, each surveillance approach fit together as “tiles in a mosaic” that provides a complete picture of respiratory viruses and the impact of associated illnesses and interventions at the country level. This mosaic framework demonstrates how surveillance approaches may be implemented as coordinated and collaborative systems, well-matched to specific priority objectives.

Soil-transmitted helminth (STH) infections are among the most common infections worldwide with an estimated 1.5 billion infected people or 24% of the world’s population. These infections affect the poorest and most deprived communities with poor access to clean water, sanitation and hygiene in tro...pical and subtropical areas, with the highest prevalence reported from sub-Saharan Africa, China, South America and Asia. They are transmitted by eggs present in human faeces, which in turn contaminate soil in areas where sanitation is poor. Over 260 million preschool-age children, 654 million school-age children,108 million adolescent girls and 138.8 million pregnant and lactating women live in areas where these parasites are intensively transmitted, and are in need of treatment and preventive interventions.

The Africa Centres for Disease Control and Prevention (Africa CDC) was established in 2017, after the west Africa Ebola virus disease outbreak. Upon creation, the
role of Africa CDC was to mandate strengthening of the capacity of public health institutions in Africa to prevent, detect, and respond ...to disease threats, based on science, policy, and data-driven interventions and programmes, as envisaged by the Abuja Declaration. The inaugural strategic plan was focused on building health systems for emergency preparedness and response. However, from its inception, the organisation recognised the concomitant need to comprehensively strengthen systems to prevent and manage noncommunicable diseases (NCDs) and injuries, and to face the neglected issue of mental health disorders. The division dedicated to these issues was conceptualised, but operationalisation was deferred to a future date.

Children with disabilities are particularly vulnerable in humanitarian settings, yet they are often not able to access the services and protection they need. While multiple factors create these barriers, a major cause is how data about children with disabilities is collected and mapped. Data collect...ion processes often exclude or underrepresent the views of children with disabilities and thier caretakers. When the experiences of children with disabilities and their caretakers are not defined and collected, they become excluded from mainstreamed protective services, which are meant to serve all children. Children with disabilities also do not get the specialised interventions they need.
This guidance note explores how to use qualitative methods to create more robust assessment processes to ensure more effective programming and services for children with disabilities. This note provides promising practices for engaging with children with disabilities and includes sample tools that can be tailored to fit the needs of a particular assessment process. The note also explores the importance of thoughtful cross-sectoral responses so that children with disabilities, and their families, are carefully considered in areas like water, sanitation, and hygiene (WASH), education, health, and nutrition, and therefore receive the holistic support they need and deserve.
This note is intended for a broad audience of relevant child protection actors, including practitioners, coordination groups, researchers, and donors. The information is not limited to one type of humanitarian setting, geographic region, or culture. As a result, the practices and guidance should be adapted to each specific context, ideally in partnership with well-informed local actors, such as representatives from local organisations for persons with disabilities.

the leadership of the Government of South Sudan, we developed the Health Sector Strategic Plan to define the strategic
approaches, key interventions, mapping resource needs, and the implementation framework to strengthen the health system
to deliver essential quality health services equitably for 2023 to 2027. For WHO, this Plan will usher in a new reality -- access
to lifesaving or health-promoting interventions is doable and possible, making the health sector fairer, especially for those

Integrating neglected tropical diseases into global health and development: fourth WHO report on neglected tropical diseases evaluates the changing global public health landscape; assesses progress towards the 2020 targets; and considers the possible core elements of a strategic vision to integratin...g neglected tropical diseases into the 2030 Agenda of the Sustainable Development Goals.
Advances have been made through expanded interventions delivered through five public health approaches: innovative and intensified disease management; preventive chemotherapy; vector ecology and management; veterinary public health services; and the provision of safe water, sanitation and hygiene. In 2015 alone nearly one billion people were treated for at least one disease and significant gains were achieved in relieving the symptoms and consequences of diseases for which effective tools are scarce; important reductions were achieved in the number of new cases of sleeping sickness, of visceral leishmaniasis in South-East Asia and also of Buruli ulcer.
The report also considers vector control strategies and discusses the importance of the draft WHO Global Vector Control Response 2017–2030. It argues that veterinary public health requires a multifaceted approach across the human–animal interface as well as a multisectoral programme of work to protect and improve the physical, mental and social well-being of humans, including veterinary, water, sanitation and hygiene.
Integration of activities and interventions into broader health systems is crucial, and despite challenges, has the potential to accelerate progress towards universal health coverage while advancing the 2030 Agenda.
In short, this report drives the message home that “no one must be left behind”.

Vector-borne diseases are responsible for 17% of the global burden of communicable diseases and more than 500 000 deaths annually. The ambitious global targets for the control of vector-borne diseases come in the context of the (re-)emergence of diseases, increasing resistances to insecticides and u...ncertainty related to the financing of global vector control efforts. The United Nations 2030 Agenda with its related Sustainable Development Goals (SDGs), the New Urban Agenda adopted at the United Nations Conference on Housing and Sustainable Urban Development (Habitat III)
in Quito in 2016 and WHO’s Global vector control response 2017–2030 (WHO, 2017a) emphasize the value of elevating multisectoral actions and strategies that extend beyond the health sector to the core of integrated vector control.
This policy brief underlines the important role housing conditions have in the transmission of vector-borne diseases and showcases interventions and policies the housing sector can contribute to effective, integrated and intersectoral vector-borne diseases management.

Obesity in all age groups, including children and adolescents, is a public health challenge across all settings. Obesity is now classified as a complex multifactorial chronic disease and not just a risk factor for other noncommunicable diseases and comorbidities. Recognizing the significance of prim...ary health care for an effective and efficient response to the obesity epidemic, the World Health Organization (WHO) has developed guidance on how to build capacity in the health system to deliver health services for prevention and management of obesity across the life course. This policy brief discusses the challenges and opportunities for preventing obesity in children and adolescents, and providing health services to treat and manage those already living with obesity. It outlines possible interventions through the primary health care approach.

Globally, over two million women live with obstetric fistula with the majority of the cases
being from Africa. In low-resource settings such as Zambia, obstetric fistula (OF) is a visible indicator of
gaps in maternal health care resulting in failure to provide adequate, accessible and quality m...aternal health
care, including family planning, skilled birth attendance, basic and emergency obstetric and neonatal care,
and affordable treatment of fistula. OF is preventable and treatable, and no woman in Zambia should continue to endure the condition. It is therefore necessary that Zambia intensifies national scale up of OF management centers including
community based interventions, train more surgeons and other health workers to provide quality and
affordable care closer to the women who are silently suffering from obstetric fistula.

This guideline provides updated, evidence-informed guidance on the percentage of total fat in the diet to reduce the risk of unhealthy weight gain.
This guideline is intended for a wide audience involved in the development, design and implementation of policies and programmes in nutrition and pub...lic health. This guideline includes a recommended level of total fat intake which can be used by policy-makers and programme managers to address various aspects of dietary fat in their populations through a range of policy actions and public health interventions.
The guidance in this guideline replaces previous WHO guidance on total fat intake, including that from the 1989 WHO Study Group on Diet, Nutrition and the Prevention of Chronic Diseases and the 2002 Joint WHO/FAO Expert Consultation on Diet, Nutrition and the Prevention of Chronic Diseases. The guidance in this guideline should be considered in the context of that from other WHO guidelines on healthy diets.

Background: Primary health care (PHC) is a driving force for advancing towards universal health coverage (UHC). PHC-oriented health systems bring enormous benefits but require substantial financial investments. Here, we aim to present measures for PHC investments and project the associated resource ...needs. Methods: This modelling study analysed data from 67 low-income and middle-income countries (LMICs). Recognising the variation in PHC services among countries, we propose three measures for PHC, with different scope for included interventions and system strengthening. Measure 1 is centred on public health interventions and outpatient care; measure 2 adds general inpatient care; and measure 3 further adds cross-sectoral activities. Cost components included in each measure were based on the Declaration of Astana, informed by work delineating PHC within health accounts, and finalised through an expert and country validation meeting. We extracted the subset of PHC costs for each measure from WHO’s Sustainable Development Goal (SDG) price tag for the 67 LMICs, and projected the associated health impact. Estimates of financial resource need, health workforce, and outpatient visits are presented as PHC investment guide posts for LMICs.

Pathogen genomic surveillance has become a priority for public health systems in recent years. Genomic sequencing is increasingly being used to characterize pathogens and monitor important public health priorities (e.g. poliovirus, influenza virus, Mycobacterium tuberculosis and Vibrio cholerae, ant...imicrobial resistance (AMR)). The decrease in cost and time of sequencing and the exponential development of bioinformatic pipelines have played a critical role in integrating pathogen genomics into routine public health surveillance. The coronavirus disease 2019 (COVID-19) pandemic has highlighted the role that sequencing plays in the surveillance of infectious diseases. Sequencing facilitates earlier detection, more accurate investigation of outbreaks, closer real-time monitoring of pathogen evolution and tailored development and evaluation of interventions to inform local to global public health decision-making and action. However, there remains a need to coordinate efforts, leverage and link existing surveillance and laboratory networks and capabilities, and systematically integrate genetic sequence data (GSD) with clinical and epidemiological data to strengthen its utility.

The Commission on Macroeconomics and Health (CMH) was established by World Health Organization Director-General Gro Harlem Brundtland in January 2000 to assess the place of health in global economic development. Although health is widely understood to be both a central goal and an important outcome ...of development, the importance of investing in health to promote economic development and poverty reduction has been much less appreciated. We have found that extending the coverage of crucial health services, including a relatively small number of specific interventions, to the world’s poor could save millions of lives each year, reduce poverty, spur economic development, and promote global security.
