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 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.

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.

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

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 third 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. This book aims to give an up-date overview to the epidemiology (including molecular typing), specific biological, immunological and immunopathological aspects, diagnosis and perspectives of control of the most common helminth infections.

This second edition of Bench aids for the diagnosis of intestinal parasites is intended both as a practical tool for the diagnosis of intestinal parasitic infections for laboratory and field workers and as a teaching aid for students and trainees. The plates are arranged on two sides: the recto with microphotographs for the identification of eggs larvae trophozoites cysts and oocysts occurring in faeces and the verso dedicated to the different copromicroscopical methods (procedures) and main staining techniques used in parasitology. Special attention has been devoted to all graphical and pictorial contents. The decision to include the outline of an Ascaris lumbricoides egg in its relative size next to each parasitic structure fulfils the intention of visualizing the actual dimensions that the eye needs to be looking for when examining the specimens with a microscope. For each image the size of the parasite and a short description are provided to assist in the microscopical identification. Two summary plates one for helminths and the other for protozoa are also included to provide a visual overview of the different presentations of parasitic elements. The bench aids have been produced in a weatherproof plastic-sealed format that is robust and easy to use at the bench. They are recommended for use by all health workers engaged in the routine diagnosis of intestinal parasitic infections.
