Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

The introduction of vaccines for coronavirus disease 2019 (COVID-19) added another measure to the existing set of
recommended preventive measures (wearing a mask in public, keeping a distance from other people and regular handwashing). The roll-out of the vaccines, however, raised concerns that vac...cination may lead to lower adherence to the existing
preventive measures. The advice from the World Health Organization (WHO) was to continue these public health and
social measures after being vaccinated.1 However, evidence from other epidemics suggests that there is lower adherence to
preventive measures when some level of protection exists (for example, individuals who use human immunodeficiency virus
pre-exposure prophylaxis

The development of this target product profile (TPP) was led by the WHO Department of Control of Neglected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG) was form...ed, and different subgroups were created to advise on specific NTDs, including a subgroup working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of independent experts included leading scientists, public health officials and endemic-country end-user representatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of the available products and of the development pipeline was conducted, and the salient areas with unmet needs were identified.

Sexual exploitation, sexual abuse and sexual harassment (SEAH) violate the rights and wellbeing of the people we serve and the people with whom we serve. Such behaviours are directly in opposition to WHO’s values and our abiding responsibility to do no harm. WHO uses the umbrella term “sexual mi...sconduct” to encompass the full spectrum of prohibited and unwanted behaviour of a sexual nature (including rape and sexual assault) as described in WHO’s 2023 Policy for preventing and addressing sexual misconduct (1). This is because all such acts are prohibited – whether perpetrated by WHO’s own personnel or by implementing partners – and therefore constitute misconduct. The term sexual misconduct is also easier to communicate and translate, as
victims and survivors do not always understand the complicated acronyms and definitions used by the United Nations (UN) and the humanitarian sector. However, we use the terms sexual misconduct and SEAH interchangeably as required when we interact with UN and other stakeholders.

To enhance health co-benefits across urban policies which tackle air pollution and climate change, WHO, in cooperation with various international, national, and local partners, implemented the Urban Health Initiative (UHI) pilot project in Accra, Ghana. The Initiative prompted the health sector to u...se its influential position to demonstrate to decision-makers and the public the full range of health, environmental and economic benefits that can be achieved from implementing local emission reduction and energy access policies and strategies. Policy tracking, although not always considered, is a fundamental component of this procedure. It assesses the planning, implementation and progress of a policy to refine or adjust policies with the final objective of increasing the likelihood of the policy being successful. This report is an outcome of the last component of the UHI model process, Policy tracking and monitoring outcomes. The report proposes a framework for tracking urban health policies, with a special focus on the impacts of air quality and energy access on human health and well-being in African countries, giving some examples from the pilot project in Accra. The report also provides resources to survey air quality in cities and other tools to assess public health and the environmental impacts of urban policies and monitor or track their effects.

Violence against women and girls is widespread in the Region of the Americas, resulting in enormous consequences for the health and wellbeing of women and girls, their families and communities. These costs are unacceptable and they can be prevented through evidence-based action, including the health... sector through its policies and protocols, as well as in collaboration with other sectors. This report remains the first of its kind and is a major milestone for the Region. It is specifically informed by the commitments of Member States in the regional Strategy and Plan of Action on Strengthening the Health System to Address Violence against Women. The report provides an analysis of efforts to advance the prevention of violence against women through health policies, clinical protocols, multisectoral plans and related approaches across the Americas. Attention to this topic is timely, as the COVID-19 pandemic has created new visibility for this area of work. This report offers critical information on efforts in the Region that can be learned from and used to build upon in the future to prevent and respond to violence against all women and girls everywhere.

During the 17 years since Surgical approaches to the urogenital manifestations of lymphatic filariasis was first published, there has been heightened awareness of the physical, economic and emotional burden of the genitourinary manifestations of filariasis. With the impetus to provide better guidanc...e for care of those suffering from LF, this update was both warranted and timely.
At the outset, the Committee noted that barriers continue to exist in care of patients affected by LF-associated morbidity. These barriers include lack of information for patients as well as for many healthcare providers, including general surgeons and others within health systems
This update offers a new consensus of the Committee regarding the staging of hydroceles caused by LF, also known as “filariceles”. It recommends integrating LF surgery with other efforts to strengthen surgical care by assessing health facilities for their surgical readiness using the WHO surgical assessment tool or “SAT”. It also recommends integratinghernia surgery with hydrocele surgery and integrating standards for prevention of surgical site infection (SSI).
The update revises recommendations for standard procedures and processes, offers an algorithm for diagnosis (including the use of ultrasound) and discusses postoperative care. It recommends collecting data using the staging and grading system described by Capuano and Capuano along with other metrics for public health management of LF.
A multifaceted approach has therefore been recommended to coordinate public health outreach with national surgical planning and local health systems to include supporting partners such as nongovernmental organizations. Surgical camps with mobile teams, as well as training of personnel at DCP3 “first level” or WHO Level II hospitals (depending on region and resources), have important roles for reducing LF morbidity.

The chapter Dementia in Latin America and the Caribbean: Prevalence, Incidence, Impact, and Trends over Time, is part of the publication series titled “Decade of Healthy Aging: situation and challenges”. This document aims to provide an outline of the current situation in Latin America and the C...aribbean in respect of the prevalence and incidence of dementia and its impact on the health status of older people. As dementia is a significant global health problem which also has social and economic impacts this document highlights the importance of monitoring dementia in the region. The document evidences that dementia is one of the main contributors to dependence and disability in older people in Latin America and the Caribbean and, although its prevalence and incidence increase exponentially with age, it is not part of normal aging. Alzheimer’s disease is the most common dementia, and there is no cure for this condition, but with timely diagnosis is possible to ameliorate symptoms. It is important to assess what are the needs of people leaving with dementia and their families and to integrate dementia risk reduction strategies in pre-existing strategies for other non-communicable diseases. As shown in the report, despite the huge burden dementia is still underdiagnosed, and it is fundamental to better monitor its prevalence, incidence and the different societal impact that dementia can have. For that, it is crucial to promote the use of harmonized methodologies to address this information in a broader number of studies and countries in the region. This can contribute to the generation of direct actions to decrease dementia risk and lead to healthier lives for people with dementia and their families.

Colombia is characterized by a fragile and prolonged humanitarian context marked by recurrent multi-hazards affecting its territories and combined with severe structural and systemic challenges within the health system. Recent shocks, including the
COVID-19 pandemic, growing violence within the Col...ombian territories and along the border with Venezuela (Bolivarian Republic of), and repetitive hydro-meteorological disasters over the last 12 months aggravate such chronic challenges.
In 2022, the number of people in need of humanitarian assistance increased by 300 000 due to deteriorating indicators of maternal and child mortality, pregnancy in adolescent girls, human immunodeficiency virus (HIV), suicides, sexually transmitted
infections (STIs), gender-based and sexual violence, and communicable diseases. increasing population trends, primarily due to mass migration movements and the persistence of armed conflicts, create access barriers to essential health services, mobility restrictions, and forced displacement, further impacting the health, lives, and well-being of populations in vulnerable situations. In many territories, geographical distance to health facilities and attacks against medical missions hinder providing appropriate healthcare.

This publication describes the first WHO public-benefit Target Product Profiles (TPPs) for snakebite antivenoms. It focuses on antivenoms for treatment of snakebite envenoming in sub-Saharan Africa. Four TPPs are described in the document:
Broad spectrum Pan-African polyvalent antivenoms: products ...that are intended for widespread utility throughout sub-Saharan Africa for treatment of envenoming irrespective of the species of snake causing a bite. Monovalent antivenoms for specific use cases: for products for a single species (or genus) of snake (e.g., boomslangs or carpet viper antivenoms).
Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.

A System of Health Accounts 2011: Revised Edition provides an updated and systematic description of the financial flows related to the consumption of health care goods and services. As demands for information increase and more countries implement and institutionalise health accounts according to the... system, the data produced are expected to be more comparable, more detailed and more policy relevant. It builds on the original OECD Manual, published in 2000, and the Guide to Producing National Health Accounts to create a single global framework for producing health expenditure accounts that can help track resource flows from sources to uses. It is the result of a collaborative effort between the OECD, WHO and the European Commission, and sets out in more detail the boundaries, the definitions and the concepts – responding to health care systems around the globe – from the simplest to the more complicated.

The Leprosy Programme and Transmission Assessment (LPTA) is an activity that is carried out by internal teams towards the end of Phase 1 (see Leprosy Elimination Framework in the Annex) when a subnational jurisdiction (typically second-tier) reaches the milestone for interruption of transmission, i....e., zero autochthonous child cases for a consecutive period of five years. It also needs to be done at the end of Phase 2, when the second milestone of elimination of leprosy disease has been reached. An LPTA will be carried out to document that all relevant programme criteria have been met and examine trends of epidemiological indicators in such jurisdiction to confirm that the milestone has been achieved. The LPTA includes assessment of health facilities that provide leprosy services. LPTA comprises of review of epidemiological data, health facility assessment and data validation and verification of the programme criteria through observation during a field visit. The evidence collected in this way in subnational health administrative units is compiled in a Leprosy Elimination Dossier to be submitted to WHO when the country reaches the milestone for elimination of disease in the country as whole. Countries that have not detected any new leprosy cases in the past three years or more can use the LPTA at national level prior to or as part of the verification process. Countries likely to be among the first to apply for verification may have had no new cases detected for more than 10 years.

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.
