ETIOLOGY OF HELMINTHIASES AND THE PATHOLOGIES THEY CAUSE

Abstract

Parasitic diseases are among the most widespread human diseases. Currently , of the 1415 known pathogens that cause human diases, 353 are protozoan and helminthic parasites. Predictions made in the late 20^th century that most parasitic  diseases would  come under control have not been realized.  The purpose of this article is to highlight the etiological factors and transmission mechanism of helminth infections, to describe their clinical and photological effects on human health, and to substantiate effective diagnostic and preventive approaches used for the detection and control of helminthiases.
