This book was released on 2022-12-15 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The WHO Department of Control of Neglected Tropical Diseases (NTD) manages a diverse portfolio of twenty diseases, each with its own unique challenges, including the diagnostic aspect. In order to identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG) was formed, and a specific subgroup was created to advise on the human African trypanosomiasis (HAT) diagnostic innovation needs. The purpose of this TPP is to communicate the minimum and ideal characteristics desired to meet the need for a simpler and more performant test able to confirm an infection with Trypanosoma brucei gambiense, usable by non-specialised personnel in the context of disease elimination. The primary target audience is the potential developers of diagnostic tests and the potential donors that could provide funding for this tools that are considered priorities by the experts convened by WHO.

This book was released on 2024-05-03 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypanosomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on Neglected tropical diseases, adopted in 2013. National sleeping sickness control programmes (NSSCPs) are core to progressing in the control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for these achievements. More than 20 years of partnership among WHO, Sanofi and Bayer have enabled WHO to strengthen and sustain financial, technical and material support for the implementation of control activities in countries where HAT is endemic. The long-term support from the Government of Belgium, the Bill & Melinda Gates Foundation (BMGF) and other research institutions in the Democratic Republic of the Congo (DRC) has also been essential. WHO convened the fifth stakeholders meeting on the elimination of HAT due to infection with Trypanosoma brucei gambiense (g-HAT) and Trypanosoma brucei rhodesiense (r-HAT) in Geneva, Switzerland, on 7–9 June 2023. The meeting was held again in person after the coronavirus disease (COVID-19) pandemic and jointly for both forms of the disease. The previous meetings on g-HAT held in 2014, 2016 and 2018, as well as on r-HAT in 2015, 2017 and 2019, and jointly for g-HAT and r-HAT in 2021 (8) reinforced the partnership and commitment for HAT elimination and structured the mechanisms of collaboration within the WHO network for HAT elimination. The network includes NSSCPs, groups developing new tools, international and nongovernmental organizations involved in disease control, and donors. Fewer than 1000 cases of HAT annually have been reported over the past 5 years, which is a historic achievement. The area at risk has been substantially reduced. The elimination of HAT as a public health problem at the global level has been achieved. The new road map for neglected tropical diseases (NTDs) 2021−2030 (“the road map”) with the target to interrupt the transmission of g-HAT requires the strengthened and sustained efforts of all stakeholders, national authorities and partners, under WHO coordination. It will take disproportionally high efforts and innovative strategies to find the last cases of g-HAT and neutralize its transmission. Given the limited resources and other competing public health priorities, this is a challenge that requires our joint commitment.

This book was released on 2023-01-30 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Global report on neglected tropical diseases 2023 provides a consolidated, up-to-date assessment of progress towards control, elimination and eradication of 20 diseases and disease groups (NTDs) globally, regionally and nationally. Progress is reported in the context of global commitments, strategies and targets set in the NTD road map 2021-2030. The document covers the first two years of implementation of the road map (2021 and 2022). The information presented is based primarily on epidemiological and programmatic data for interventions conducted in 2021 and gathered in 2022, but the report also describes a wide range of activities and accomplishments that were registered in both 2021 and 2022; comparisons are often made against 2020 and 2019 data, especially with regard to COVID-19 disruptions. It has four sections: Section 1 is an introduction. Section 2 presents the status of the global NTD response. Section 3 charts progress and developments against the three road map pillars. Section 4 sets out priority actions for 2023 and beyond to sustain implementation of the road map and its companion documents. Five annexes to the report provide information for 2021–2022 on regional progress (Annex 1), Weekly Epidemiology Record articles on NTDs (Annex 2), progress and challenges by disease (Annex 3), diagnostic target product profiles (Annex 4) and the status of commitments for donated medicines and health products (Annex 5).
Download or read book Progress in Human African Trypanosomiasis Sleeping Sickness written by Michel Dumas and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human African Trypaniosomiasis (HAT) or sleeping sickness is an old disease to be now considered as reemergent. HAT is endemic in 36 sub-Saharan African countries, in areas where tsetse flies are found. The public health importance of HAT is underestimated, but the disease causes severe social disruption in many rural areas. Along the past fifteen years, numerous studies were made, and now, the mechanisms involved in the disease pathogenesis and in the characteristics of sleep-wake disruption become to be better understood. But, since 50 years, when current drugs were introduced, problems regarding HAT chemotherapy have not been solved. Nevertheless, in-depth studies about trypanosome metabolism have permitted to discover new drug targets. Written by specialists who are very experienced in their respective fields, the contributions provide an indispensable tool for practitioners and scientists.

This book was released on 2015-08-05 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

This book was released on 2005 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This field manual is intended to help health professionals and public health coordinators working in emergency situations prevent, detect and control the major communicable diseases encountered by affected populations. The manual is the result of collaboration among a number of WHO departments and several external partner agencies in reviewing existing guidelines on communicable disease control and adapting them to emergency situations. The manual deals with the fundamental principles of communicable disease control in emergencies, which are: Rapid assessment to identify the communicable disease threats faced by the emergency-affected population, including those with epidemic potential, and define the health status of the population by conducting a rapid assessment; Prevention to prevent communicable disease by maintaining a healthy physical environment and good general living conditions; Surveillance to set up or strengthen disease surveillance system with an early warning mechanism to ensure the early reporting of cases to monitor disease trends, and to facilitate prompt detection and response to outbreaks; outbreak control to ensure outbreaks are rapidly detected and controlled through adequate preparedness (i.e. stockpiles, standard treatment protocols and staff training) and rapid response (i.e.confirmation, investigation and implementation of control measures); and disease management to diagnose and treat cases promptly with trained staff using effective treatment and standard protocols at all health facilities.

This book was released on 1996-03-20 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relative lack of information on determinants of disease, disability, and death at major stages of a woman's lifespan and the excess morbidity and premature mortality that this engenders has important adverse social and economic ramifications, not only for Sub-Saharan Africa, but also for other regions of the world as well. Women bear much of the weight of world production in both traditional and modern industries. In Sub-Saharan Africa, for example, women contribute approximately 60 to 80 percent of agricultural labor. Worldwide, it is estimated that women are the sole supporters in 18 to 30 percent of all families, and that their financial contribution in the remainder of families is substantial and often crucial. This book provides a solid documentary base that can be used to develop an agenda to guide research and health policy formulation on female health--both for Sub-Saharan Africa and for other regions of the developing world. This book could also help facilitate ongoing, collaboration between African researchers on women's health and their U.S. colleagues. Chapters cover such topics as demographics, nutritional status, obstetric morbidity and mortality, mental health problems, and sexually transmitted diseases, including HIV.
Download or read book Drug Discovery for Leishmaniasis written by Luis Rivas and published by Royal Society of Chemistry. This book was released on 2017-10-26 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: For human health, leishmaniasis is among the most important protozoan diseases, superseded only by malaria. Globally, 10 to 12 million people are infected with 1.5 million new cases every year. The development of cheaper new drugs is urgently needed for this neglected disease that is developing resistance to current treatments. Chemotherapy remains the only treatment option for the bulk of patients. However, this is largely unaffordable for most. In the past three years numerous advances in drug discovery have been made for treating this disease by exploiting diverging metabolic pathways between the Leishmania enzymes and their hosts, using nanotechnology to target the immune cell phagolysosomes where Leishmania resides. Drug Discovery for Leishmaniasis aims to provide a perspective of the current treatments and their challenges, blended with the emerging strategies and methodologies that will drive new target appraisals and drug developments, as well as addressing the molecular basis of resistance in Leishmania. Recent studies have shown that leishmaniasis affects some of the poorest people in the world, with 95% of fatal cases occurring in only 6 countries. With the WHO goal of eliminating this public health problem in the South-east Asia Region by 2020, this book will be important for anyone who is interested in neglected tropical diseases.

Download or read book Lost Sex written by Isa Schön and published by Springer Science & Business Media. This book was released on 2009-09-22 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.

Department of Control of Neglected Tropical Diseases and published by World Health Organization. This book was released on 2010 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Neglected tropical diseases (NTDs) blight the lives of a billion people worldwide and threaten the health of millions more. These ancient companions of poverty weaken impoverished populations, frustrate the achievement of health in the Millennium Development Goals and impede global health and economies has convinced governments, donors, the pharmaceutical industry and other agencies, including nongovernmental organizations (NGOs), to invest in preventing and controlling this diverse group of diseases. Global efforts to control "hidden" diseases, such as dracunculiasis (guinea-worm disease), leprosy, gains including the imminent eradication of dracunculiasis. Since 1989 (when most endemic countries began reporting monthly from each endemic village), the number of new dracunculiasis cases has fallen from 892 055 in 12 endemic countries to 3190 in 4 countries in 2009, a decrease of more than 99%. The World Health Organization (WHO) recommends five public-health strategies for the prevention and control of NTDs: preventive chemotherapy; intensified case-management; vector control; the provision of safe water, sanitation and hygiene; and veterinary public health (that is, applying veterinary sciences to ensure the health and well-being of humans). Although one approach and delivered locally." - p. vii

This book was released on 2016-07-27 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This toolkit for integrated vector management (IVM) is designed to help national and regional programme managers coordinate across sectors to design and run large IVM programmes. It is an extension of earlier guidance and teaching material published by the World Health Organization (WHO): Handbook for integrated vector management Monitoring and evaluation indicators for integrated vector management Guidance on policy-making for integrated vector management and Core structure for training curricula on integrated vector management. The toolkit provides the technical detail required to plan implement monitor and evaluate an IVM approach. IVM can be used when the aim is to control or eliminate vector-borne diseases and can also contribute to insecticide resistance management. This toolkit provides information on where vector-borne diseases are endemic and what interventions should be used presenting case studies on IVM as well as relevant guidance documents for reference. The diseases that are the focus of this toolkit are malaria lymphatic filariasis dengue leishmaniasis onchocerciasis human African trypanosomiasis and schistosomiasis. It also includes information on other viral diseases (Rift Valley fever West Nile fever Chikungunya yellow fever) and trachoma. If other vector-borne diseases appear in a country or area vector control with an IVM approach should be adopted as per national priorities. Malaria as one of the most important vector-borne diseases in sub-Saharan Africa is the main focus of this document. Programmes targeting other vector-borne diseases can learn from the experiences gained from malaria vector control and presented here.
