human roundworm

Human roundworms, primarily *Ascaris lumbricoides*, are large parasitic worms that live in the intestines. People become infected by ingesting eggs through contaminated food, water, or soil. Once inside, the eggs hatch into larvae, which travel through the body before settling in the intestines and growing into adult worms. These worms can cause symptoms such as abdominal discomfort, nausea, or malnutrition, especially in large numbers. Infection can be prevented by good hygiene, proper sanitation, and washing food thoroughly. Treatment involves anti-parasitic medications that effectively eliminate the worms.
