Ascariasis is caused by in taking food or drink contaminated with roundworm eggs. Ascariasis is the most common intestinal worm infection. It is found in association with poor personal hygiene, poor sanitation, and in places where human feces are used as fertilizer.
Treatments consist of medications that paralyze or kill intestinal parasitic worms, such as albendazole or mebendazole.
Ascariasis is a human disease caused by the parasitic roundworm Ascaris lumbricoides. Maybe as many as one quarter of the world's people are infected, and ascariasis is particularly prevalent in tropical regions and in areas of poor sanitation. Other species of the genus Ascaris are parasitic and can cause disease in domestic animals. Infection occurs through ingestion of food contaminated with feces containing Ascaris eggs. The larvae hatch, burrow through the intestine, reach the lungs, and finally migrate up the respiratory tract. From there they are then reswallowed and mature in the intestine, growing up to 30 cm (12 in.) in length and anchoring themselves to the intestinal wall.
