This comprehensive volume covers all aspects from the historical discovery of the filarial parasite Loa loa to the latest diagnostics and therapies for all forms of pathology used at the point of care. Current developments in these areas are also highlighted. Expert authors present the epidemiological impact of loiasis and the basic mechanisms underlying the disease in native populations and nonresidents of endemic areas. In addition to particulars on the immunology of the parasite, its general and molecular biology, the clinical manifestation is also described in detail. Both common and atypical clinical manifestations are considered. This book concludes with an outlook on further research and targeted eradication of the disease. Loa loa , known as the "eye worm", is endemic in the rural populations of several African countries and is transmitted by rainforest deerflies. It displays impressive immune adaptation with a wide range of clinical symptoms that remain largely unexplored. The characteristics of this nematode make it of great interest to physicians and researchers specializing in infectious diseases, epidemiology, and immunology. In addition, students and family physicians working with African immigrants and travelers should know about this parasite. Loiasis is a prime example of a neglected disease under the conditions of international health efforts in our globalized world. The present work is intended to promote progress in this field, making it a valuable read within the scope of the UN Sustainable Development Goal 3 (Good Health and Well-Being).
