Elephantiasis is a medical condition characterized by severe swelling, usually in the legs, arms, or genitals. This swelling occurs due to the blockage of lymphatic vessels, often caused by parasitic infections, particularly from the Wuchereria bancrofti worm. The condition can lead to thickening of the skin and significant discomfort, impacting a person's quality of life. The disease is most commonly found in tropical and subtropical regions, where the parasites are transmitted through mosquito bites. Early diagnosis and treatment are crucial to prevent severe complications. Preventive measures include controlling mosquito populations and improving sanitation in affected areas.
