What is a possible consequence of untreated filariasis?

The consequence of untreated filariasis that most appropriately fits this context is elephantiasis. Filariasis is caused by parasitic worms, particularly lymphatic filariasis, which is primarily transmitted through mosquito bites. When these parasites invade the lymphatic system, they can lead to severe swelling and enlargement of body parts, most notably the limbs and genitals, resulting in a condition known as elephantiasis. This is characterized by extreme swelling and thickening of the skin, resembling the rugged hide of an elephant, hence the name.

In contrast, while malnutrition and weight loss may occur in individuals suffering from various parasitic infections due to overall health decline, they are not direct consequences of filariasis itself. Additionally, inflammation of the intestines typically relates to gastrointestinal infections or diseases rather than filariasis, which primarily affects the lymphatic system. Therefore, elephantiasis stands out as a significant and recognizable effect of untreated filariasis.
