Ascaris infection is brought on by Ascaris lumbricoides, an intestinal roundworm, or, on occasion, by Ascaris suum (which causes ascariasis in pigs). It is one of the most prevalent worm diseases globally, although it is rare in the United States.
Moreover, ascariasis is especially prevalent in regions without contemporary sanitation. The parasite is transmitted by contaminated food and drink. Usually, there are no symptoms associated with this illness; however, heavier infestations (a large number of roundworms) might cause issues in the lungs or intestines.
