1.5 Epidemiology, parasitology and biology of lymphatic filariasis: (Distribution, causal agent, Life cycle, transmission dynamics and Culex vector) 1.5.1 Geographic Distribution: The distribution of lymphatic filariasis is limited to the tropical and subtropical countries mainly in Africa, the Mediterranean area and South East Asia (WHO, 1998). It is also occurs in Western Pacific and West Indies Islands. 1.5.2 Adult worm: The creamy white, thread like adults of both sexes lie tightly coiled in the nodular dilations of the lymphatic vessels and sinuses of the lymphndes. Female worm measures 80-100 × 0.25 mm and the male 40× 0.1mm, being about half the size of female.
