Lymphatic Filariasis (also known as Elephantiasis) is transmitted to man by the bite of infected Culex, Anopheles, and Aedes mosquitoes. The infective larvae mature to adults, males and females, in lymphatic vessels and nodes where female worms produce microfilariae which then circulate in the bloodstream. A mosquito bite of an infected human host then completes the cycle. In Bancroftian filariasis, the time from infection to appearance of microfilariae is 6-12 months while in Brugian filariasis it may be only 3 ½ months. Microfilariae generally circulate in the bloodstream at night, but can be daytime in some regions. This is referred to as the periodicity. Adult worms live 4-6 years.
caused by nematode worms which develop in the lymphatic system and release vast numbers of tiny larvae into the blood. - The worms may obstruct the lymph ducts and cause swelling of the limbs known as elephantiasis.
- Infection in man is chronic and serious and symptoms develop over many years of continual biting by mosquitoes.
