"This report provides a review and analysis of the research landscape for three diseases--Chagas disease, human African Trypanosomiasis and leishmaniasis--that dispropotionally afflict poor and remote populations with limited access to health services. It represents the work of the disease reference group on Chagas Disease, human African Trypanosomiasis, and leishmaniasis (DRG3) which was established to identify key research priorities through review of research evidence and input from stakeholders' consultations. The diseases, which are caused by related protozoan parasites, are described in terms of their epidemiology and disease burden, clinical forms and pathogenesis, HIV coinfection, diagnosis, drugs and drug resistance, vaccines, vector control, and health-care interventions. Priority areas for research are identified based on criteria such as public health relevance, benefit and impact on poor populations and equity, and feasibility. The priorities are found in the areas of diagnostics, drugs, vector control, asymptomatic infection, economic analysis of treatment and vector control methods, and in some specific issues such as surveillance methods or transmission-blocking vaccines for particular diseases. This report will be useful to researchers, policy and decision makers, funding bodies, implementation organizations, and civil society."--P. 4 of cover.
The Thematic Reference Group on Environment, Agriculture and Infectious Diseases of Poverty (TRG 4) addresses the nature of the intersections and interactions between environment, agriculture and infectious diseases of poverty in order to identify research priorities for improved disease control. This report reviews the connections between environmental change, modern agricultural practices and the occurrence of infectious diseases--especially those of poverty--and proposes a methodology that can be used to prioritize research on such diseases. Although there is some comprehension of the underlying and growing systemic influence of today s large-scale social and environmental changes on some infectious diseases, the significance and potential future impacts of these changes are poorly understood. Nevertheless, such changes now constitute a significant influence on the working of the Earth's systems that will have increasing consequences for patterns of occurrence of infectious diseases. Many of these changes are illustrated in this report. A common theme of this report is bidirectional causation, effectively "trapping" complex, linked eco-social systems in stable states that are resistant to intervention. For example, poverty is associated with ill health, low education and often with poor diets, either because of under-nutrition (and diarrhoea) or intakes that have excessive calories but insufficient micronutrients. In either case, poverty impairs health; and ill health impairs the escape from poverty. Another example is provided by a recent abundant agricultural harvest in India that has far exceeded storage capacity. A substantial fraction of this harvest will be wasted due to inadequate storage. Some grain that is badly stored will be contaminated by aflatoxins and other fungi, which increases the risk of cancer. This report presents the case for a more integrated approach across sectors, research disciplines and diseases, taking greater account of the increasingly widespread and systemic influences on disease emergence and spread.
This book contains 11 chapters of significant and updated materials on what we know and what we lack and need in better understanding of Trypanosoma cruzi - a parasite that never dies - and the consequences of Chagas disease as one of the most important neglected parasitic diseases threatening the global health and wellbeing. This book is intended to increase the readers' enthusiasm to explore the four sections of the contents: Section 1 begins with biochemistry, pathophysiology, histo-immunological study, and findings to assist in the diagnosis; Section 2 further investigates the role of vector in propagation of the parasite, the intensity on epidemiology, and the severity on clinical aspects, which help us to be well perceived on the course of disease; Section 3 is seeking beyond modern medicine and what lays in the nature that helps fight against this parasite; and the last section, Section 4, deals with the impacts of public health problem and the control strategies on Chagas disease.
This book provides a comprehensive resource on various aspects of the parasite Trypanosoma cruzi and the neglected tropical disease Chagas disease (American trypanosomiasis), the disorder resulting from infection with the parasite. Topics include the biological description and taxonomy of the parasite, epidemiology and transmission routes, laboratory techniques in use when working with the parasite, as well as diagnostic measures and treatment of Chagas disease. Furthermore, a chapter with life stories of people in contact with the disease in endemic as well as non-endemic countries is included. The book is therefore a valuable source for individuals engaged in basic research as well as patient care and health management related to American trypanosomiasis.
"The presence, or absence, of neglected tropical diseases (NTDs) can be seen as a proxy for poverty and for the success of interventions aimed at reducing poverty. Today, coverage of the public-health interventions recommended by the World Health Organization (WHO) against NTDs may be interpreted as a proxy for universal health coverage and shared prosperity - in short, a proxy for coverage against neglect. As the world's focus shifts from development to sustainable development, from poverty eradication to shared prosperity, and from disease-specific goals to universal health coverage, control of NTDs will assume an important role towards the target of achieving universal health coverage, including individual financial risk protection. Success in overcoming NTDs is a "litmus test" for universal health coverage against NTDs in endemic countries. The first WHO report on NTDs (2010) set the scene by presenting the evidence for how these interventions had produced results. The second report (2013) assessed the progress made in deploying them and detailed the obstacles to their implementation. This third report analyses for the first time the investments needed to achieve the scale up of implementation required to achieve the targets of the WHO Roadmap on NTDs and universal coverage against NTDs. INVESTING TO OVERCOME THE GLOBAL IMPACT OF NEGLECTED TROPICAL DISEASES presents an investment strategy for NTDs and analyses the specific investment case for prevention, control, elimination and eradication of 12 of the 17 NTDs. Such an analysis is justified following the adoption by the Sixty-sixth World Health Assembly in 2013 of resolution WHA6612 on neglected tropical diseases, which called for sufficient and predictable funding to achieve the Roadmap's targets and sustain control efforts. The report cautions, however, that it is wise investment and not investment alone that will yield success. The report registers progress and challenges and signals those that lie ahead. Climate change is expected to increase the spread of several vector-borne NTDs, notably dengue, transmission of which is directly influenced by temperature, rainfall, relative humidity and climate variability primarily through their effects on the vector. Investments in vector-borne diseases will avoid the potentially catastrophic expenditures associated with their control. The presence of NTDs will thereby signal an early warning system for climate-sensitive diseases. The ultimate goal is to deliver enhanced and equitable interventions to the most marginalized populations in the context of a changing public-health and investment landscape to ensure that all peoples affected by NTDs have an opportunity to lead healthier and wealthier lives."--Publisher's description.
Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.
The pharmacopoeias of most African countries are available and contain an impressive number of medicinal plants used for various therapeutic purposes. Many African scholars have distinguished themselves in the fields of organic chemistry, pharmacology, and pharmacognosy and other areas related to the study of plant medicinal plants. However, until now, there is no global standard book on the nature and specificity of chemicals isolated in African medicinal plants, as well as a book bringing together and discussing the main bioactive metabolites of these plants. This book explores the essence of natural substances from African medicinal plants and their pharmacological potential. In light of possible academic use, this book also scans the bulk of African medicinal plants extract having promising pharmacological activities. - The book contains data of biologically active plants of Africa, plant occurring compounds and synthesis pathways of secondary metabolites - This book explores the essence of natural substances from African medicinal plants and their pharmacological potential - The authors are world reknowned African Scientists
Neglected tropical diseases (NTDs) is a diverse group of communicable diseases that prevail in tropical and subtropical conditions in 149 countries. NTDs affect more than one billion people and cost developing economies billions of dollars every year. According to the World Health Organization (WHO), NTDs mainly affect populations living in poverty, without adequate sanitation, and in close contact with infectious vectors, domestic animals, and livestock. Migration, as well as climate change and variability, are key factors in NTD prevalence. Therefore, NTDs deserve more study. Recently, viruses transmitted by vectors (arboviruses) that affect not only people living in the tropics, but also travelers and migrating populations, have been causing epidemics. Examples of these viruses include Dengue, Chikungunya, Zika, Mayaro, and encephalitis viruses. These viruses emerge and reemerge in multiple regions of the world, as occurred in the Americas recently (2013-2017) with Chikungunya and Zika. This book aims to update the significant epidemiological and clinical research of NTDs in many aspects with a multinational perspective.
