LYMPHATIC FILARIASIS - Lymphatic filariasis is a debilitating Blood disease caused by nematode worms of the genera Wucheriaand Brugia. Larval worms circulate in the Bloodstream of infected persons, and adult worms live in the lymphatic vessels. Lymphatic filariasis is not life threatening, but it does cause extreme discomfort, swelling of the limbs and genitals, damage to the kidneys and lymphatic system, impairment of the body’s ability to fight infection, and general malaise. In addition, it produces immeasurable emotional and economic costs in terms of the disruption of family and community life.
