inal answer:
Infection by the filarial worm is typically carried through the bite of an infected mosquito. It causes a condition called lymphatic filariasis, which leads to the enormous swelling of affected body parts known as elephantiasis.
Step-by-step explanation:
Infection by the filarial worm is typically carried through the bite of an infected mosquito. When a mosquito bites an individual who is infected with filarial worms, it ingests the microscopic larvae. The larvae then develop inside the mosquito and migrate to its mouthparts. When the mosquito bites another person, it injects the larvae into their bloodstream, where they mature into adult worms.
The enormous swelling of affected body parts seen in filarial worm infection is due to a condition called lymphatic filariasis. When the adult worms live in the human lymphatic system, they obstruct the flow of lymph fluid, causing the accumulation of fluid and leading to severe swelling. This condition is commonly known as elephantiasis, which most often affects the legs and groin area.
