Abstract
Parasitic worms (helmints) can be found worldwide, although a higher occurrence is visible in tropical and sub-tropical areas. Pathogenesis of parasitic diseases, principles of diagnostic and therapeutical procedures, necessity of information prior to travel to risk areas and preventive and anti-epidemic countermeasures can be well understood only with precise knowledge of the parasitic biology.
An important part of the patient's clinical examination is his or her personal and travel history and adequate sampling for laboratory examination
