This companion document to Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021-2030 ("the road map") aims to support a range of stakeholders - including countries in which neglected tropical diseases (NTDs) are endemic, international organi...zations and non-State actors - to achieve the road map targets through a transdisciplinary, cross-cutting One Health approach. Specifically, it provides guidance on the One Health actions needed by major stakeholders and how to support a paradigm shift towards One Health in national NTD programmes. Examples of common One Health challenges and how they can be overcome as well as illustrative cases studies are provided throughout. The companion document was developed through a global consultative process involving stakeholder interviews, interactive workshops, and online public consultation.

Abstract: Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chaga...s disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss the current status of acute Chagas disease cases globally, the immunological findings related to the acute phase and their possible influence in disease outcome, and reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV invection management.

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

Cutaneous leishmaniasis (CL) is a neglected infectious endemic disease that is transmitted through the bite of a vector insect (sandfly) of the Lutzomyia genus,typical of rural geographical territories, and causes disfiguring skin ulcers and disabilities. It is estimated that CL affects between 600...000 and 1 000 000 people a year around the world, mainly in the America s, the Mediterranean basin, the Middle East and Central Asia. Eighteen of the 21 countries that make up the Latin American (LA) region are considered endemic areas for this neglected tropical disease. Colombia is one of the countries that reports the majority of global cases with 6161 in 2020 and has the second highest number of cases in the Americas, after Brazil.

This perspective draws on the record of ancient pathogengenomes and microbiomes illuminating patterns of infectious disease over the course of the Holocene in order toaddress the following question. How did major changes inliving circumstances involving the transition to and intensification of farmi...ng alter pathogens and their distributions? Answers to this question via ancient DNA researchprovide a rapidly expanding picture of pathogen evolution and in concert with archaeological and historical data, give a temporal and behavioral context for heath in the past that is relevant for challenges facing the world today, including the rise of novel pathogens.

Mycetoma is a specific chronic, granulomatous, inflammatory disease. It usually involves the subcutaneous tissue, most probably after traumatic inoculation of the causative organism. It has a prolonged, progressive, and indolent course, and, if untreated, it ultimately leads to destruction of the de...eper tissues and bone, resulting in deformity and disability that may necessitate amputation of the affected parts with all the social and economic implications of this. The disease is characterized by tumefaction, draining sinuses, and the presence of grains.

Rabies remains an under-reported neglected zoonosis with a case-fatality rate of almost 100% in humans and animals. Dog-mediated human rabies causes tens of thousands of human deaths annually despite being 100% preventable. More than 95% of human cases are caused by the bite of a rabies-infected dog.... Dog-mediated human rabies disproportionately affects rural communities, particularly children, and economically disadvantaged areas of Africa and Asia, where awareness of the disease and access to appropriate post-exposure prophylaxis (PEP) can be limited or nonexistent.

A aplicação da tecnologia digital de saúde está crescendo rapidamente na África, com o
objetivo de melhorar a prestação de serviços de saúde e alcançar de forma mais eficaz
comunidades remotas e carentes. A falta de diretrizes e padrões habilitadores em todo o
continente, por outro ...lado, dificulta o compartilhamento de dados de forma significativa em
todo o continente. Considerando isso, os Centros Africanos de Controle e Prevenção de
Doenças (CDC África) estabeleceram uma força-tarefa de 24 membros para fornecer
experiência e orientação no desenvolvimento de diretrizes e padrões da AU HIE. Os membros
da força-tarefa eram especialistas no assunto que trabalhavam na África e
internacionalmente na coleta, análise e troca de informações de saúde. Alguns desses
especialistas estiveram envolvidos em consultas anteriores sobre a definição da estratégia de
sistemas de informação de saúde do CDC África. Um presidente, copresidente e secretário
foram eleitos para envolver os membros da força-tarefa em diferentes grupos de trabalho
técnicos.

A Estrutura de Vigilância Baseada em Eventos deve ser usada por autoridades e agências responsáveis
pela vigilância e resposta. Essa estrutura serve como um esboço para orientar as partes interessadas
em implementar a vigilância baseada em eventos (EBS) usando uma abordagem multissetorial ...de One
Health. Para esse fim, o documento é organizado em capítulos e anexos interligados que podem ser
modificados e adaptados, conforme necessário, pelos usuários.
Esta é uma versão revisada da “Estrutura para Vigilância Baseada em Eventos” original, publicada em
2018. Essa estrutura não substitui nenhum outro material disponível do EBS, mas se baseia em
documentos relevantes ou relacionados existentes e serve como um guia prático para a
implementação do EBS na África. Essa estrutura está alinhada com a terceira edição da Avaliação
Externa Conjunta da OMS para os seguintes indicadores: sistemas de vigilância de alerta precoce
fortalecidos que são capazes de detectar eventos importantes para a saúde pública e a segurança da
saúde (Indicador D2.1); melhor comunicação e colaboração entre os setores e entre os níveis de
autoridade de resposta à saúde pública nacional, intermediário e local em relação à vigilância de
eventos importantes para a saúde pública (Indicador D2.2); e melhor capacidade nacional e
intermediária de analisar dados ( Indicador D2.3). À medida que os países começarem a implementar
e demonstrar a funcionalidade do EBS, eles garantirão um aumento nas pontuações do JEE e
progredirão no cumprimento dos requisitos descritos no IHR 3F.
.
Além disso, nos Estados Membros da União Africana que adotaram a estratégia Integrada de
Vigilância e Resposta a Doenças (IDSR), este documento é um complemento e pode aprimorar a
implementação do IDSR, especialmente para a 3ª edição (2019), que inclui componentes
relacionados ao EBS.

There is an expanding market of no- and low-alcohol beverages (NoLos). However, their effects on global ethanol consumption and public health are still questioned. Policies and regulations about NoLos’ availability, acceptability and affordability are lacking and evidence about their benefits is l...imited. Concerns have been raised about the impact of NoLos in reducing alcohol consumption and its associated harm and the possible drawbacks and implications, such as misleading minors, pregnant women, abstainers or those seeking to stop drinking about their actual ethanol content. Further, there are concerns about the implications of NoLo branded products being displayed close to the brand’s main alcoholic beverages and their potential to subtly lead to new occasions of drinking. There is a need to monitor their consumption and impact on aggregated alcohol consumption to understand the public health implications of NoLos. The alcohol by volume content of NoLos must be defined, harmonised and clearly labelled. NoLo marketing needs to be regulated to protect children, pregnant women and those seeking to stop drinking. Fiscal and pricing policies to reduce the affordability of products with higher strengths of ethanol may favour a shift towards lower alcohol strength beverages.

La serovigilancia es una herramienta que complementa los métodos tradicionales de salud pública para la vigilancia de las enfermedades transmisibles y proporciona información valiosa sobre la transmisión de enfermedades en los grupos de la población; por ejemplo, para detectar brechas en la inm...unidad frente a las enfermedades prevenibles mediante vacunación. Esta información es útil para hacer un seguimiento de la exposición de la población a enfermedades como la malaria, las enfermedades infecciosas desatendidas, las enfermedades transmitidas por alimentos, agua y vectores, así como las enfermedades infecciosas emergentes. Como muchas enfermedades infecciosas están o han estado presentes en grupos que viven en entornos donde se superponen diversos factores de riesgo, la serovigilancia integrada facilita las sinergias y optimiza la utilización de los recursos de salud pública. Este conjunto de herramientas se elaboró para facilitar el diseño, la puesta en marcha, el análisis, la interpretación y el uso de los resultados de las encuestas serológicas integradas para reforzar las capacidades de los países con vistas a la eliminación de las enfermedades transmisibles. En la primera parte se describen los conceptos básicos sobre encuestas y vigilancia serológicas, sus usos, ventajas y desafíos, formas de mejorar su eficiencia, así como su potencial para contribuir a la toma de decisiones de salud pública. Posteriormente, se presenta un proceso gradual para la puesta en marcha de la vigilancia serológica integrada basada en encuestas serológicas. Incluye recomendaciones sobre cómo determinar la necesidad y el propósito de recopilar información serológica; el diseño y la metodología de la encuesta; los métodos del laboratorio; las consideraciones prácticas para la realización de encuestas; el análisis e interpretación de los datos y el uso de los resultados para respaldar la toma de decisiones. Su objetivo principal es apoyar a los directores de programas y equipos que participan en el control y eliminación de las enfermedades transmisibles. Se elaboró para ser usado, entre otros, por los coordinadores de enfermedades transmisibles, enfermedades infecciosas desatendidas y programas de vacunación; directores de vigilancia epidemiológica; personal de laboratorios de salud pública; y otros profesionales de los ministerios de salud y autoridades nacionales y subnacionales de salud que puedan estar interesados en incorporar la vigilancia serológica integrada como parte de las herramientas de sus sistemas de vigilancia, para obtener información adicional sobre la transmisión de enfermedades infecciosas en la población.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

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.

A erradicação da varíola humana (mpox em inglês) foi certificada em 1980. A varíola símia (mpox em inglês) é endêmica nos países da África Central e Ocidental desde a sua primeira detecção, em 1958. Trata-se de uma zoonose cujos casos geralmente ocorrem perto de florestas tropicais, ond...e diversos animais são portadores do ortopoxvírus causador da doença. A maioria das infecções em seres humanos pelo vírus da varíola símia em países onde a doença é endêmica é resultado de transmissão primária de animais para humanos. A transmissão de pessoa a pessoa pode ocorrer por meio de contato próximo com secreções respiratórias ou lesões cutâneas de uma pessoa infectada ou com objetos recém-contaminados. A transmissão também pode ocorrer através da placenta da mãe para o feto ou por contato direto durante ou após o parto. Até 21 de maio de 2022, 12 países onde não há varíola símia endêmica, em 2 regiões da Organização Mundial da Saúde (OMS), haviam notificado 92 casos confirmados da doença. Até 26 de agosto de 2022, 96 países sem endemicidade, de todas as 6 regiões da OMS, haviam notificado 45.198 casos confirmados de varíola símia, incluindo 6 óbitos. No mesmo período, os países onde a doença é endêmica notificaram 350 casos confirmados e 6 óbitos. Na Região das Américas, 29 países e territórios notificaram 23.479 (48%) casos confirmados e 3 óbitos. Diversos estudos observacionais sobre as vacinas de primeira geração demonstraram que a eficácia da vacinação contra a varíola humana na prevenção da varíola símia é de aproximadamente 85%. Atualmente, as vacinas originais (de primeira geração) contra a varíola humana não estão mais disponíveis.

Data on asthma aetiology in Africa are scarce. We investigated the risk factors for asthma among schoolchildren (5–17 years) in urban Uganda. We conducted a case-control study, among 555 cases and 1115 controls. Asthma was diagnosed by study clinicians. The main risk factors for asthma were tertia...ry education for fathers (adjusted OR (95% CI); 2.32 (1.71–3.16)) and mothers (1.85 (1.38–2.48)); area of residence at birth, with children born in a small town or in the city having an increased asthma risk compared to schoolchildren born in rural areas (2.16 (1.60–2.92)) and (2.79 (1.79–4.35)), respectively; father’s and mother’s history of asthma; children’s own allergic conditions; atopy; and cooking on gas/electricity. In conclusion, asthma was associated with a strong rural-town-city risk gradient, higher parental socio-economic status and urbanicity. This work provides the basis for future studies to identify specific environmental/lifestyle factors responsible for increasing asthma risk among children in urban areas in LMICs.

Asthma is the most common chronic respiratory disease (CRD) worldwide and is estimated to affect 262 million causing significant mortality and morbidity, and has emerged as an important public health problem in many Latin American (LA) countries over the last 30 or so years. LA is a highly diverse r...egion in terms of geography, climate, wealth, and ethnicity including 20 different countries with 639 million inhabitants, where 40 million are estimated to have asthma. A common feature of LA countries is the high level of social inequalities3 (Figure 1). In LA, asthma prevalence in both children and adults is highly variable and, where high, is among the highest worldwide, particularly in coastal tropical cities.
