Parasitic infections in travelers and immigrants: part II helminths and ectoparasites

Abstract

ABSTRACT  Travel and migration contribute to the emergence of certain parasites which may be imported into nonendemic areas. Noncontrolled importation of food products and animals may also contribute to the diagnosis of infections caused by helminths in nonendemic countries. Some helminth infections such as strongyloidiasis may be life-threatening, especially in immunocompromised patients, and outcome depends on correct diagnosis and treatment. Other helminth infections are neglected tropical diseases associated with chronic disease and/or disability. Major challenges concern the development of improved diagnostic techniques, safer and more effective drug therapies and identification of markers of response to treatment. The study of these imported infections in travelers and immigrants may provide opportunities for research which may not be readily available in resource-poor endemic countries. Updated reviews and guidelines are necessary as new data become available. The second part of this review focuses on infections in travelers and immigrants caused by helminths and ectoparasites.
