Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire...ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

ince the introduction of multidrug therapy (MDT), there has been significant progress in reducing the prevalence of leprosy and the occurrence of new cases. Global strategies have evolved with progress in reducing the disease burden. Encouraged by the decrease in the number of cases on treatment, th...e World Health Assembly passed a resolution calling on Member States to accelerate efforts towards global elimination of leprosy as a public health problem by 2000.
Most countries reached the milestone by 2010. The global strategies for 2006–2015 focused on sustaining high-quality leprosy services and early diagnosis. Reduction in the disease burden was measured in terms of grade-2 disability (G2D) or visible deformities in new cases. Since 2016, the strategies have included reduction of stigmatization of people with leprosy.

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.

The document, titled "Prevention and Control of Noncommunicable Diseases: Guidelines for Primary Health Care in Low-Resource Settings," provides the World Health Organization's (WHO) recommendations for managing noncommunicable diseases (NCDs) such as cancer, heart disease, diabetes, and chronic res...piratory illnesses in low-resource healthcare settings. It outlines cost-effective interventions for early diagnosis, treatment, and prevention within primary healthcare, focusing on accessible methods for diabetes management, blood pressure control, dietary and lifestyle guidance, and essential medication use. The guidelines aim to support healthcare professionals in delivering effective NCD care where resources are limited, ultimately improving health outcomes and reducing NCD complications.

The report “Dementia: a public health priority” has been jointly developed by WHO and Alzheimer's Disease International. The purpose of this report is to raise awareness of dementia as a public health priority, to articulate a public health approach and to advocate for action at international a...nd national levels.
Dementia is a syndrome that affects memory, thinking, behaviour and ability to perform everyday activities. The number of people living with dementia worldwide is currently estimated at 35.6 million. This number will double by 2030 and more than triple by 2050. Dementia is overwhelming not only for the people who have it, but also for their caregivers and families. There is lack of awareness and understanding of dementia in most countries, resulting in stigmatization, barriers to diagnosis and care, and impacting caregivers, families and societies physically, psychologically and economically.

Buruli ulcer is caused by Mycobacterium and belongs to the family of bacteria that causes tuberculosis and leprosy. Although the causative organism of Buruli ulcer is an environmental bacterium, the mode of transmission to humans remains unknown. The organism produces a unique toxin – mycolactone ...– that causes the damage to the skin. Early diagnosis and treatment are crucial to minimizing morbidity, costs and prevent long-term disability.

Heart failure with a reduced ejection fraction (HFrEF) is a condition frequently encountered by healthcare professionals and, in order to achieve the best outcomes for patients, needs to be managed optimally. This guideline document is based on the European Society of Cardiology Guidelines for the t...reatment of acute and chronic heart failure published in 2016, and summarises what is considered the best current management of patients with the condition. It provides information on the definition, diagnosis and epidemiology of HFrEF in the African context. The best evidence-based treatments for HFrEF are discussed, including established therapies (beta-blockers, ACE-i/ARBs, mineralocorticoid receptor antagonists (MRAs), diuretics) that form the cornerstone of heart failure management as well as therapies that have only recently entered clinical use (angiotensin receptor-neprilysin inhibitor (ARNI), sodium/glucose cotransporter-2 (SGLT2) inhibitors). Guidance is offered in terms of more invasive therapies (revascularisation, implantable cardioverter defibrillators (ICDs) and cardiac resynchronisation therapy (CRT) by implantation of a biventricular pacemaker with (CRT-D) or without (CRT-P) an ICD, left ventricular assist device (LVAD) use and heart transplantation) in order to ensure efficient use of these expensive treatment modalities in a resourcelimited environment. Furthermore, additional therapies (digoxin, hydralazine and nitrates, ivabradine, iron supplementation) are discussed and advice is provided on general preventive strategies (vaccinations). Sections to discuss conditions that are particularly prevalent in sub-Saharan Africa (HIV-associated cardiomyopathy (CMO), peripartum CMO, rheumatic heart disease, atrial fibrillation) have been added to further improve clinical care for these commonly encountered disease processes.

Breast cancer is the most common cancer worldwide and the leading cause of cancer deaths among women, disproportionately affecting low- and middle-income countries. The Global Breast Cancer Initiative strives to reduce breast cancer mortality by 2.5 percent per year, which over a 20-year period can ...save 2.5 million lives. The purpose of this core technical package is to outline a pathway for incremental, sustainable improvements tailored to country-specific needs based on three key strategies and objectives: health promotion for early detection; timely diagnosis; and comprehensive breast cancer management. This document provides a common framework linking policy makers, stakeholders, the clinical community, program managers and civil society to evidence-based systematic approaches that can facilitate health systems strengthening and reduce inequities in women’s health throughout their life cycles

Tuberculosis (TB) is the leading cause of death from a single infectious agent even if is largely curable and
preventable. In 2019 an estimated 2.9 million of the 10 million people who fell ill with TB were not
diagnosed or reported to the World Health Organization1. The Politi...cal Declaration adopted by the United
Nations General Assembly in September 2018 commits, amongst others, to diagnosing and treating 40
million people with TB. In order to achieve these ambitious targets, there is an urgent need to deploy
strategies to improve diagnosis and initiation of care for people with TB. One of them is systematic
screening for TB disease, which is included in the End TB Strategy as a central component of its first pillar
to ensure early diagnosis for all with TB.

Policy brief.
Globally, one in five people with HIV are unaware of their status, despite considerable scale up of HIV testing, treatment and prevention services. Many of those unreached by HIV testing services (HTS) are from key populations, partners of people with HIV and, in Eastern and southern ...Africa, men and young people. Improving the availability, accessibility, friendliness and quality of services is important to address these testing gaps.
At the same time, tools and interventions that increase the demand for HTS are needed to reach people who are uninformed about HTS options and advances in treatment and prevention, people who are not motivated to seek HTS and those who are hesitant to test because of fear of an HIV diagnosis or other reasons.

Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people ...living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5–15% of AIDS-related deaths every year in this Region. These guidelines aim to provide recommendations for the diagnosis, treatment, and management of disseminated histoplasmosis in persons living with HIV

Young children are especially susceptible to exposure to trauma. Rates of abuse and neglect among this population are staggering. This article presents a review of relevant literature, including research findings specific to early childhood vulnerability to trauma, symptoms associated with traumatic... events, diagnostic validity of early childhood trauma, and treatments for young children. In the past, misconceptions about the mental health of young children have hindered accurate diagnosis and treatment of trauma-related mental illness. Due to the prevalence of trauma exposure in early childhood, counselors are encouraged to become familiar with ways that clients and families are impacted and methods for treatment. Implications for future research also are presented.

Viral hepatitis is defined as inflammation of the liver cells due to viral infection. The burden of liver disease in South Africa is mostly underestimated as viral hepatitis, in particular chronic infection, is a silent and neglected cause of morbidity and mortality. However, the burden of disease i...s likely substantial given the prevalence of chronic viral hepatitis. This burden is further compounded by the lack of screening and access to care and treatment as well as inadequate disease surveillance, human and financial resources.
The National Guidelines for the Management of Viral Hepatitis were developed, with the purpose to:
inform healthcare workers in the public and private sectors about the disease, its epidemiology in South Africa and current methods of diagnosis and therapy
strengthen the healthcare response to viral hepatitis
empower communicable diseases workers and stakeholders to make informed decisions regarding appropriate and cost effective interventions

Chagas disease or American trypanosomiasis is, together with geohelminths, the neglected disease that causes more loss of years of healthy life due to disability in Latin America. Chagas disease, as determined by the factors and determinants, shows that different contexts require different actions, ...preventing new cases or reducing the burden of disease. Control strategies must combine two general courses of action including prevention of transmission to prevent the occurrence of new cases (these measures are cost effective), as well as opportune diagnosis and treatment of infected individuals in order to prevent the clinical evolution of the disease and to allow them to recuperate their health. All actions should be implemented as fully as possible and with an integrated way, to maximise the impact. Chagas disease cannot be eradicated due because of the demonstrated existence of infected wild triatomines
in permanent contact with domestic cycles and it contributes to the occurrence of at least few new cases. However, it is possible to interrupt the transmission of Trypanosoma cruzi in a large territory and to eliminate Chagas disease
as a public health problem with a dramatic reduction of burden of the disease.

The World Health Organization (WHO) defines mental health as ‘a state of well-being in which the individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community’. Mental illn...ess refers to all of the diagnosable mental disorders, which are characterised by abnormalities in thinking, feelings or behaviours. Mental illness is closely related to vulnerability, both in its causes and in its effects. Globally, 14 per cent of the global burden of disease is attributed to mental illness – with 75 per cent of those affected being found in low-income countries – which includes a broad spectrum of diagnoses, from common mental illnesses such as anxiety and
substance abuse, to severe illnesses like psychosis.

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally kn...own as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.
