APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Transmission. Soil-transmitted helminths are transmitted by eggs that are passed in the faeces of infected people. Adult worms live in the intestine where they produce thousands of eggs each day. In areas that lack adequate sanitation, these eggs contaminate the soil.

Detailed explanation-2: -Helminths, transmitted by contact with soil and known as Soil Transmitted Helminths (STH) or intestinal parasites, are the most common infections worldwide and affect the poorest and most vulnerable populations. The causative agents are Ascaris lumbricoides, Trichuris trichiura, and hookworms.

Detailed explanation-3: -Many species of the helminths, or parasitic worms, of livestock and poul-try can pass through certain of their early stages only within the body of an insect. These species are transmitted, in the true sense, by insects. Beetle mites or grass mites similarly transmit others.
