Filarial

More than one billion people in 80 countries are at risk of contracting lymphatic filariasis, known as elephantiasis, which is transmitted by mosquitos infected with parasitic filarial worms. The worms lodge in the lymphatic system, causing accumulations of lymph fluid that lead to massive swellings of limbs, usually the feet.

The knowledge of a filarial infection of the region of the eye seems to date from the time of Magellan.

From a cosmetic standpoint, the filarial diseases [...] were especially unfortunate.

Other helminths or wormlike fellow travellers became common in the human gut, including the Enterobius (pinworm or threadworm), the yards-long tapeworm, and the filarial worms which cause elephantiasis and African river blindness.
