Innovative Strategies For Vector Control

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.

Current tools for vector control are insufficient to curb vector-borne disease transmission. Recent outbreaks of 'new' vector-borne diseases, such as Zika and chikungunya, and the ongoing fight against malaria underscore this. Scientists and public health authorities collaborate on a continued search for innovative strategies to address this challenge. To guide the integration of currently available and new tools in vector control programs, the World Health Organization (WHO) developed the Global Vector Control Response (GVCR).This initiative was unanimously endorsed by the World Health Assembly in 2017. This 6th volume of the 'Ecology and Control of Vector-borne Diseases' series reflects on the progress of GVCR by reviewing:(1) innovative strategies for vector control that are in the pipeline; (2) the role of integrated vector management (IVM) in these strategies; and (3) inclusion of social aspects of IVM, such as community engagement, in effective control programs. The introduction and concluding chapters of the book have been written in collaboration with WHO.

This book comprehensively covers the latest development in developing and deploying the genetically modified vectors, particularly Anopheles and Aedes mosquitoes responsible for transmitting malaria parasites and dengue viruses, the most deadly and/or debilitating among all the vector-borne diseases. It is considered timely and commensurate to bring about a book dealing with the various ecological, biological and social as well as regulatory aspects for the deployment of genetically modified vectors in special context with the biosafety of humans, his associates, and the environment. Written by an array of specialists and experts in various subjects of genetically modified organisms, this book centrally addresses the (i) basic principles of the genetic manipulation of vectors and they are potential impact on human and the environment, (ii) ecological, biological, ethical, legal and social implications of the use of genetically modified vectors, (iii) identification of potential hazards; assessment and management of risks for human and environment; risk/benefit analysis, (iv) principles and practices for the assessment and management of biosecurity and biosafety in laboratories (and in the field), (v) guiding principles for creation and management of institutional or national biosafety review boards and ethics review committees, and (vi) development and application of a biosafety regulatory framework and its related legal principles at national levels for securing the development and use of vector control methods based on genetic modification strategies. This publication will be useful to researchers, scientists, and professionals engaged in academic and research institutions, government or non-government, as well as students in universities and medical colleges.

This book was first published in 1990. It discusses a plethora of both high and low tech options for the control of vectors such as mosquitos in the spread of disease.

Pathogens transmitted among humans, animals, or plants by insects and arthropod vectors have been responsible for significant morbidity and mortality throughout recorded history. Such vector-borne diseases â€" including malaria, dengue, yellow fever, and plague â€" together accounted for more human disease and death in the 17th through early 20th centuries than all other causes combined. Over the past three decades, previously controlled vector-borne diseases have resurged or reemerged in new geographic locations, and several newly identified pathogens and vectors have triggered disease outbreaks in plants and animals, including humans. Domestic and international capabilities to detect, identify, and effectively respond to vector-borne diseases are limited. Few vaccines have been developed against vector-borne pathogens. At the same time, drug resistance has developed in vector-borne pathogens while their vectors are increasingly resistant to insecticide controls. Furthermore, the ranks of scientists trained to conduct research in key fields including medical entomology, vector ecology, and tropical medicine have dwindled, threatening prospects for addressing vector-borne diseases now and in the future. In June 2007, as these circumstances became alarmingly apparent, the Forum on Microbial Threats hosted a workshop to explore the dynamic relationships among host, pathogen(s), vector(s), and ecosystems that characterize vector-borne diseases. Revisiting this topic in September 2014, the Forum organized a workshop to examine trends and patterns in the incidence and prevalence of vector-borne diseases in an increasingly interconnected and ecologically disturbed world, as well as recent developments to meet these dynamic threats. Participants examined the emergence and global movement of vector-borne diseases, research priorities for understanding their biology and ecology, and global preparedness for and progress toward their prevention, control, and mitigation. This report summarizes the presentations and discussions from the workshop.

Vector-borne infectious diseases, such as malaria, dengue fever, yellow fever, and plague, cause a significant fraction of the global infectious disease burden; indeed, nearly half of the world's population is infected with at least one type of vector-borne pathogen (CIESIN, 2007; WHO, 2004a). Vector-borne plant and animal diseases, including several newly recognized pathogens, reduce agricultural productivity and disrupt ecosystems throughout the world. These diseases profoundly restrict socioeconomic status and development in countries with the highest rates of infection, many of which are located in the tropics and subtropics. Although this workshop summary provides an account of the individual presentations, it also reflects an important aspect of the Forum philosophy. The workshop functions as a dialogue among representatives from different sectors and allows them to present their beliefs about which areas may merit further attention. These proceedings summarize only the statements of participants in the workshop and are not intended to be an exhaustive exploration of the subject matter or a representation of consensus evaluation. Vector-Borne Diseases : Understanding the Environmental, Human Health, and Ecological Connections, Workshop Summary (Forum on Microbial Threats) summarizes this workshop.

Towards Malaria Elimination - A Leap Forward was started to mark the occasion for renewed commitment to end malaria transmission for good (the WHO's call for "Malaria Free World" by 2030). This book is dedicated for the benefit of researchers, scientists, program and policy managers, students and anyone interested in malaria and other mosquito-borne diseases with the goal of sharing recent information on success stories, innovative control approaches and challenges in different regions of the world. Some main issues that emerged included multidrug-resistant malaria and pandemic risk, vaccines, cross-border malaria, asymptomatic parasite reservoir, the threat of Plasmodium vivax and Plasmodium knowlesi, insecticide resistance in Anopheles vectors and outdoor malaria transmission. This book is one little step forward to bring together in 17 chapters the experiences of malaria-expert researchers from five continents to present updated information on disease epidemiology and control at the national/regional level, highlighting the constraints, challenges, accomplishments and prospects of malaria elimination.

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.
