Lymphatic filariasis


Lymphatic filariasis is spread by infected mosquitoes. Their bites deposit a parasite that travels to the lymph system.


Most cases are symptomless. Rarely, long-term damage to the lymph system causes swelling in the legs, arms, and genitalia. It also increases the risk of frequent bacterial infections that harden and thicken the skin (elephantiasis).


A drug taken yearly can kill the parasites.
