Diseases transmitted by insects continue to have a major impact on human populations. Malaria, dengue, onchocerciasis, sleeping sickness and leishmaniasis all adversely affect man. Malaria is one of the most important causes of child mortality and reduces economic development in many countries, with agricultural productivity often greatly reduced, as many vectors are active in the wet season favourable for crop production. Vector control is crucial to reduce the extent to which drugs are needed to treat the diseases, as the parasite can become resistant, or the drugs are often too expensive for those living in rural areas and urban slums most affected by these diseases. Chemical control of vectors is often the only method that can reduce vector populations in a disease epidemic, but with vectors developing resistance to insecticides, there is increasing awareness that a single control method is often insufficient and also that chemical control must be integrated where possible with other control measures. In Integrated Vector Management, Graham Matthews covers the main chemical methods of vector control, including the use of indoor residual spraying, space treatments, the use of treated bed nets and larviciding, but also stresses the importance of drainage schemes and improvement of houses to prevent access of indoor vectors, techniques that have largely been responsible for reducing the risk of vector borne diseases in Europe and the USA. This book combines practical information from successful vector control programmes, including early use of DDT, and recent research into a vital resource for all those now involved in combating insect vector borne diseases. Integrated Vector Management is an essential tool, not only for medical entomologists and those directly involved in government health departments, but also for all those who provide the skills and management needed to operate successful area-wide vector management programmes. Libraries in all universities and research establishments world-wide, where biological sciences, medicine and agriculture are studied and taught should have multiple copies of this important book.
This 6th volume of the ECVD series reflects on the progress of GVCR. The introduction and concluding chapters of the book have been written in collaboration with WHO.
Integrated vector management (IVM) is a rational decision-making process for optimal use of resources for vector control. The aim of the IVM approach is to contribute to achievement of the global targets set for vector-borne disease control, by making vector control more efficient, cost-effective, ecologically sound and sustainable. Use of IVM helps vector control programs to find and use more local evidence, to integrate interventions where appropriate and to collaborate within the health sector and with other sectors, as well as with households and communities. By reorientating to IVM, vector control programs will be better able to meet the growing challenges in the control of malaria, dengue and other vector-borne diseases in the face of dwindling public sector human and financial resources. This handbook presents an operational framework to guide managers and those implementing vector-borne disease control programs in designing more efficient, cost-effective systems. As a national IVM policy and an intersectoral steering committee are essential for establishing IVM as a national strategy, the handbook begins with the policy and institutional framework for IVM. Policy analysis is a means for identifying options for policy reform and suggesting instruments for implementing policy. IVM transforms the conventional system of vector control by making it more evidence-based, integrated and participative. This may require changes in roles, responsibilities and organizational links. The transition to IVM involves both reorientation of vector-borne disease control programs and embedding IVM within local health systems. Intersectoral partnerships and collaboration at both national and local levels will result in cost savings and benefits to other health services. Other relevant sectors, such as agriculture, environment, mining, industry, public works, local government and housing, should incorporate IVM and vector control into their own activities to prevent vector proliferation and disease transmission. Planning and implementing IVM involve assessing the epidemiological and vector situation at country level, analyzing the local determinants of disease, identifying and selecting vector control methods, assessing requirements and resources and designing locally appropriate implementation strategies. Solid evidence on the cost-effectiveness of interventions and their underlying parameters and a comprehensive vector surveillance system are essential for locally appropriate decision-making. Capacity-building, in particular human resource development, is a major challenge, because the IVM strategy requires skilled staff and adequate infrastructure at central and local levels. The handbook outlines the core functions and essential competence required for IVM at central and local levels, complementing a separate set of documents containing the Core structure for training curricula on integrated vector management and associated training materials. Like any new approach, IVM must be actively advocated and communicated in order to become established. The handbook lays out the elements and processes of IVM to enable policy-makers, donors and implementing partners to use it for vector-borne disease control. During the period of transition and consolidation of an IVM strategy, regular feedback is required on performance and impact in order to ensure continued support. The general public must also be made aware of the strategy and participate in its implementation. The communication tools for reaching the public are the media and various types of educational interventions to increase their knowledge and skills, which should lead to behavioral change and empowerment. The final section presents a comprehensive framework for monitoring and evaluation of IVM, covering aspects discussed in the previous sections. Indicators and methods for measuring process, outcomes and impact are proposed.
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.
This publication is intended to contribute to prevention and control of the morbidity and mortality associated with dengue and to serve as an authoritative reference source for health workers and researchers. These guidelines are not intended to replace national guidelines but to assist in the development of national or regional guidelines. They are expected to remain valid for five years (until 2014), although developments in research could change their validity.--Publisher's description.
This open access book identifies and discusses biodiversity’s contribution to physical, mental and spiritual health and wellbeing. Furthermore, the book identifies the implications of this relationship for nature conservation, public health, landscape architecture and urban planning – and considers the opportunities of nature-based solutions for climate change adaptation. This transdisciplinary book will attract a wide audience interested in biodiversity, ecology, resource management, public health, psychology, urban planning, and landscape architecture. The emphasis is on multiple human health benefits from biodiversity - in particular with respect to the increasing challenge of climate change. This makes the book unique to other books that focus either on biodiversity and physical health or natural environments and mental wellbeing. The book is written as a definitive ‘go-to’ book for those who are new to the field of biodiversity and health.
Covering the theory and practice of non-insecticidal control of insect vectors of human disease, this book provides an overview of methods including the use of botanical biocides and insect-derived semiochemicals, with an overall focus on integrated vector management strategies. While the mainstay of malaria control programmes relies on pesticides, there is a resurgence in the research and utilisation of non-insecticidal control measures due to concerns over rapid development and spread of insecticide resistance, and long-term environmental impacts. This book provides examples of successful applications in the field and recommendations for future use.
Dengue and its potentially fatal forms, dengue henorrhagic fever and dengue shock syndrome, once more threaten much of the Americas. In the 1980s the vector control programmes fell victim to the cutbacks in public health expenditure and their responses to dengue outbreaks tended to be a little too late. These guidelines have risen to the challenge by incorporating all aspects of the prevention and control of the disease and its vectors. In addition, because dengue is primarily a problem of domestic sanitation and households can combat the problem inexpensively. The guidelines enmphasize ways to transfer responsibility for dengue control and prevention to the community."
For more than 50 years, low-cost antimalarial drugs silently saved millions of lives and cured billions of debilitating infections. Today, however, these drugs no longer work against the deadliest form of malaria that exists throughout the world. Malaria deaths in sub-Saharan Africaâ€"currently just over one million per yearâ€"are rising because of increased resistance to the old, inexpensive drugs. Although effective new drugs called "artemisinins" are available, they are unaffordable for the majority of the affected population, even at a cost of one dollar per course. Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance examines the history of malaria treatments, provides an overview of the current drug crisis, and offers recommendations on maximizing access to and effectiveness of antimalarial drugs. The book finds that most people in endemic countries will not have access to currently effective combination treatments, which should include an artemisinin, without financing from the global community. Without funding for effective treatment, malaria mortality could double over the next 10 to 20 years and transmission will intensify.
