It's caused by a type of roundworm Ascaris lumbricoides. Roundworm eggs live in soil that is contaminated by feces. The eggs can get into the body through the mouth. The infection can then spread from person to person via infected feces.
Where do roundworms come from?
Roundworm infections usually happen when soil, sand, or plants that have been contaminated with infected animal feces are accidentally put in the mouth and ingested. Hookworm infections happen when larvae penetrate the skin. This usually happens when people sit or walk on contaminated soil or sand with bare feet.
How do you prevent roundworm infestation?
Hygiene. In countries where roundworms are common, roundworms may be prevented by eating only cooked food and by avoiding green vegetables and salads. It is best if children do not play in areas of poor sanitation, or where human stool (faeces) is used as fertiliser.
How do humans get roundworms?
Roundworms do pose a significant risk to humans. Contact with contaminated soil or dog feces can result in human ingestion and infection. Roundworm eggs may accumulate in significant numbers in the soil where pets deposit feces. Once infected, the worms can cause eye, lung, heart and neurologic signs in people.
