The Global Health Network is an open source platform that provides trusted knowledge, guidance, tools and resources to support the generation of more and better health research data. During emerging outbreaks it is vital to learn as much as possible to generate evidence on best practice for preventi...on, diagnosis and treatment and to facilitate effective preparedness and response for future outbreaks.
This pop-up space for 2019 Novel Coronavirus COVID-19 (formerly 2019-nCoV) supports evidence generation by pooling protocols, tools, guidance, templates, and research standards generated by researchers and networks working on the response to this outbreak. Findings from previous outbreaks, largely obtained during MERS and SARS, are also available. This all aims to make research faster and easier and to enable standardised, quality data to be collected and prepared for sharing.
Latest updates will be provided on transmission as well as recommendations for healthcare professionals on transmission, disease management, and care.

This document provides technical guidance on concepts, definitions, indicators, criteria, milestones and tools to assist leprosy programmes in their journey towards the goals of interruption of transmission and elimination of leprosy disease and through the post-elimination period. Importantly, it p...rovides criteria with benchmarks, where possible, for all key aspects of leprosy programmes and services. Not only those related to elimination efforts, but also those related to diagnosis and management of leprosy, leprosy-related disabilities, mental wellbeing, stigma and discrimination and inclusion and participation of persons affected by leprosy. The document emphasises that the elimination of leprosy is a long-term, continuous journey on the one hand, while, on the other, clear milestones can be recognised on the way and programme implementation can be assessed against benchmarks, guiding appropriate action to keep the programme on track.

Cystic fibrosis (CF) was earlier thought to be a disease prevalent in the West among Caucasians. However, quite a number of recent studies have uncovered CF cases outside of this region, and reported hundreds of unique and novel variant forms of CFTR. Here, we discuss the evidence of CF in parts of... the world earlier considered to be rare; Africa, and Asia. This review also highlighted the CFTR mutation variations and new mutations discovered in these regions. This discovery implies that the CF data from these regions were earlier underestimated. The inadequate awareness of the disease in these regions might have contributed towards the poor diagnostic facilities, under-diagnosis or/and under-reporting, and the lack of CF associated health policies. Overall, these regions have a high rate of infant, childhood and early adulthood mortality due to CF. Therefore, there is a need for a thorough investigation of CF prevalence and to identify unique and novel variant mutations within these regions in order to formulate intervention plans, create awareness, develop mutation specific screening kits and therapies to keep CF mortality at bay.

Onchocerca volvulus transmitted by repeated bites of infected blackflies (Simulium spp.). These blackflies breed along fast-flowing rivers and streams, close to remote villages located near fertile land where people rely on agriculture.
There is a need to reinforce skills of national and district... health workers to know and identify the disease, understand the risk factors according to the context and living conditions of the affected communities, and promote the implementation of public health interventions. With the shift from control to elimination, large areas in Africa require mapping to assess whether transmission is active, and treatment required. A sampling strategy named Onchocerciasis elimination mapping has been developed to help countries conduct those assessments and start treatment where needed.
This course examines the epidemiology of Onchocerciasis, clinical aspects, impact, diagnosis, treatment and control, elimination, public health interventions and role of community health workers

The article from the European Respiratory Journal discusses the natural history of chronic obstructive pulmonary disease (COPD), emphasizing its increasing global impact on morbidity and mortality. It highlights that while cigarette smoking is a primary risk factor, other influences such as environm...ental exposures and genetics also play significant roles. The article notes that lung function, measured by FEV1 (forced expiratory volume in one second), is a critical indicator of both diagnosis and prognosis. It further explores the impact of exacerbations, comorbidities, and systemic inflammation on disease progression and outcomes. The need for comprehensive patient management, which considers various comorbid conditions and inflammatory factors, is emphasized to improve clinical outcomes and reduce healthcare costs.

The objectives of these guidelines are to provide recommendations outlining a public health approach to managing people presenting with advanced HIV disease, and to provide guidance on the timing of initiation of antiretroviral therapy (ART) for all people living with HIV.
WHO recommends that a... package of screening, prophylaxis, rapid ART initiation and intensified adherence interventions be offered to everyone living with HIV presenting with advanced disease.
WHO strongly recommends that rapid ART initiation should be offered to people living with HIV following confirmed diagnosis and clinical assessment. Rapid initiation of ART is defined as within seven days of HIV diagnosis. WHO further strongly recommends ART initiation on the same day as HIV diagnosis based on the person’s willingness and readiness to start ART immediately, unless there are clinical reasons to delay treatment.

Providing quality, stigma-free services is essential to equitable health care for all and achieving global HIV goals and broader Sustainable Development Goals related to health. Every person has the right to the highest attainable standard of physical and mental health. Countries have a legal obliga...tion to develop and implement legislation and policies that guarantee universal access to quality health services and address the root causes of health disparities, including poverty, stigma and discrimination.
The health sector is uniquely placed to lead in addressing inequity, assuring safe personcentred care for everyone and improving social determinants of health by overcoming taboos and discriminatory or stigmatizing behaviours associated with HIV, viral hepatitis and sexually transmitted infections (STIs). Improving health care quality and reducing stigma work together to enhance health outcomes for people living with HIV. Together, they make health care services more accessible, trustworthy and supportive. This encourages early diagnosis, consistent treatment and improved mental well-being. Thus, people living with HIV are more likely to engage with and benefit from health care services, leading to improved overall health.

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 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.

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.
