roundworm
Elephantiasis is primarily caused by a parasitic infection, most commonly by filarial worms transmitted through mosquito bites. The infection leads to severe swelling and thickening of the skin and tissues, particularly in the limbs and genitals. In some cases, it can also be caused by non-parasitic factors, such as severe bacterial infections or lymphatic obstruction. Early diagnosis and treatment are crucial to prevent complications and reduce symptoms.
