Elephantiasis or Filariasis is caused by filarial worm Wuchereria. These worms when enter the body affect different organs and start causing chronic inflammation especially in the lymphatic vessels of lower limbs and thus results in large swelling of lower limbs. External genitalia too get affected. This condition is transmitted through female mosquitoes which act as vectors or carriers of filarial pathogens. Thus, elephantiasis is an infectious condition which requires vector for its transmission.
