Parasites Lurking in the Human Body
Roundworms are widely confirmed parasites with global infections, reportedly claiming 4,500 lives annually. Primarily residing in the human small intestine, they can cause severe symptoms such as intestinal obstruction and bile duct invasion. Developing children are particularly susceptible.
The main cause of infection is the consumption of unwashed food or water contaminated with roundworm eggs. The eggs are remarkably resilient; once ingested, they hatch in the intestines and grow into adult worms. Thorough handwashing and meticulously washing raw vegetables are essential for prevention.
