Filariasis

Filariasis is a parasitic infection caused by roundworms that are spread by mosquitoes. The roundworms, called filarial larvae, infect humans when they are bitten by an infected mosquito. The larvae travel through the blood and lymphatic system to the lungs, heart, and lymph nodes. In the lymph nodes, the larvae mature into adult worms that produce eggs which are passed out of the body in the blood or urine. When these eggs are ingested by another mosquito, the cycle continues. Symptoms of medical Filariasis include fever, rash, enlarged lymph nodes, and swelling in the arms, legs, and groin. In severe cases, it can lead to blindness, permanent disability, and even death. Treatment is available and may include medication, surgical removal of the adult worms, and lymphatic drainage.
