Historical aspects for the control of soil-transmitted helminthiases

Abstract

Japan has been one of the very few countries that operated the nationwide control programme against soil-transmitted helminths (STH) infections and gained a great success. On the basis of researches and operational studies, periodical mass-examination using cellophane thick smear (Kato technique) and selective mass-treatment targeted at school children were employed as the most useful control measure. In later years, Japan's experience and the strategy for STH control programme were transferred to Asian countries through Asian Parasite Control Organization (APCO) and also to countries of Asia, Africa and Latin-America through seminar at a modified form of the integration programme (IP) of STH control with family planning and nutritional improvement. The parasitologists group conducted studies in all aspects to seek effective STH control measures for respective countries and obtained many successful results.
