Lymphatic filariasis is commonly known as elephantiasis. Three different filarial species — Wuchereria bancrofti, Brugia malayi and Brugia timori can cause lymphatic filariasis in humans. Most of the infections in South Asia are caused by Wuchereria bancrofti as per Dr Anup Bastola, Consultant Tropical Medicine Physician at Sukraraj Tropical and Infectious Disease Hospital, Teku.
The infection spreads from person to person by the bite of culex mosquito. The adult worm lives in the human lymph vessels, mates, and produces microfilariae or microscopic worms. It circulates in the person’’s blood and infects the mosquito when it bites a person who is infected. Microfilariae grow and develop in the mosquito. When the mosquito bites another person, the larval worms pass from the mosquito into the human skin.
In Nepal, 61 of the districts are under the risk of filariasis. Lymphatic filariasis impairs the lymphatic system and can lead to the abnormal enlargement of body parts, causing pain, severe disability and social stigma. As per World Health Organisation, 856 million people in 52 countries worldwide remain threatened by lymphatic filariasis and require preventive chemotherapy to stop the spread of this parasitic infection.
