Lymphatic filariasis

Overview

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

Symptoms

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).

Treatments

A drug taken yearly can kill the parasites.
