Human helminthiasis, known as worm infections, is any macroparasitic disease affecting humans, in which a part of the body is invaded by a lot of worms, known as helminths. They are broadly classified into flukes, tapeworms, and roundworms. Soil-transmitted helminthiasis and schistosomiasis are the most important, being included into the neglected tropical diseases. Helminthiasis has been found to result in poor birth outcome, less cognitive development, lower school and work performance, lower socioeconomic development, and poverty. Soil-transmitted helminthiases are responsible for parasitic infections in as much as a quarter of the human population worldwide. This group of infective diseases has been targeted under the joint action of the world's leading pharmaceutical companies and local governments, trying to achieve their eradication.
This manual focuses on how and when a set of low-cost or free drugs should be used in developing countries to control a set of diseases caused by worm infections. Preventive chemotherapy in this context means using drugs that are effective against a broad range of worm infections to simultaneously treat the four most common diseases caused by worms: river blindness (onchocerciasis), elephantiasis (lymphatic filariasis), schistosomiasis, and soil-transmitted helminthiasis. Significant opportunities also exist to integrate these efforts with the prevention and control of diseases such as trachoma. The new approach provides a critical first step in combining treatment regimens for diseases which, although different in themselves, require common resources and delivery strategies for control or elimination.
Written by internationally respected experts, Handbook of Human Helminthiasis provides information essential in the development of an integrated approach to the prevention, control and treatment of disease caused by endoparasitic helminths. The text is divided into sections dealing with the main groups of helminth infections and the diseases they i
Parasitic diseases are the most widespread of all the major diseases, currently 9 affecting about 3 x 10 people and innumerable domestic animals. There is no doubt that among these parasitic diseases, the helminthic infections of the gastrointestinal tract are about the most important because of their global distribution, their high prevalence, their effects on the nutritional status of men and animals, their effects on the physical and mental development of children, and their economic effects on the production of animals. Anthelmintics are important elements in the control of these gastrointestinal helminthic infections. In this volume the editors and authors have tried to find a way through the immense amount of information on anthelmintic drugs that is scattered throughout the literature. Different authors have critically examined this information from different angles. However, the aim of all has been to provide the information needed by veterinarians, physicians, and public health workers to select the most suitable drug for a given situation.
Helminth infections are caused by parasitic worms (including tapeworms and roundworms). These diseases are associated with poverty, and in school-age populations in developing countries, intestinal helminth infections rank first among the causes of all communicable and noncommunicable diseases. This book is based on papers presented at an OECD conference, held in Bali, Indonesia in February 2000, which sought to review activities for the control of diseases due to soil-transmitted helminth infections in Indonesia and neighbouring countries.
This thematic volume provides authoritative, up-to-date reviews pertaining to the epidemiology, public health significance and shifts therein, control (current activities, successes, setbacks), persisting challenges (e.g. sanitation, universal coverage of health services, health-related behavior) of the key parasitic diseases in Southeast Asia. The book also discusses the new tools and approaches for enhanced discovery and control of helminthic diseases.

More than 2000 million people worldwide are affected by schistosomiasis and soil-transmitted helminth (STH) infections and 155 000 deaths are reported each year. These infections are diseases associated with poverty, and in school-age populations in developing countries, intestinal helminth infections rank first among the causes of all communicable and noncommunicable diseases. This book describes a cost-effective approach to the control of these infections, based on the use of periodic parasitological surveys of school population samples. It is intended as a guide for health education managers responsible for implementing community-based programmes.
This is a thoroughly revised edition of a well-received reference work on helminthiases and their impact on worldwide public health. The carefully presented collection covers both common and neglected helminth infections. Readers will discover an up-date overview to helminth epidemiology (including molecular typing), specific biological, immunological and immunopathological aspects, diagnosis and latest perspectives of control. New contributions give particular attention to economic consequences of helminthiases, deworming programs and future public health approaches, as well as most recent findings in host immune responses. Helminths are long-lived multicellular organisms that have co-evolved with humans over many thousands of years. They are responsible for infections which affect around one fourth of the human population, at global level. Despite the huge efforts in research during the last years, effective control of helminth infections is still far from optimal standards and the resulting diseases remain neglected. The highly readable link of parasitological background and clinical application makes this book a valuable read not only for parasitologists but also physicians and medical students, health professionals as well as experts in public health issues. Moreover, all readers concerned with combating neglected parasitoses towards the Sustainable Development Goal SDG 3 (Good Health and Well-being) will understand the significance of this renewed volume.

Just as the magnitude of the growth and developmental problems attributable to human helminthiasis are being fully realized, we are able for the first time to describe defined immune responses giving rise to the pathological lesions seen. On the basis of the different sets of cytokines produced by CD4+ T cells, these responses can be classified according to the Th1/Th2/Th0 paradigm. Deleterious inflammatory responses to metazoan parasites appear to be consistently associated with a highly polarized Th2 cytokine profile. Thus, host-parasite models involving specific enteric and tissue helminths have provided seminal data on immunoregulatory and immunopathogenetic responses that are more broadly generalizable to the entire Th1/Th2 paradigm. The first three articles in this volume present an overview of recent advances in the understanding of the induction of IgE, eosinophilic, and cytokine regulatory responses to helminthic infection. Subsequent articles comprehensively review immunopathogenetic aspects of schistosomiasis, hookworm infection, echinococcosis, lymphatic filariasis, onchocerciasis, toxocariasis, and cysticercosis, and, at the same time, emphasize key directions and priorities. Conclusions from animal models of infection are set in the context of human disease wherever possible. For all immunologists with an interest in cytokine biology and for those interested in the biology of tropical infectious diseases this volume is essential reading.
