Pinworm infection in Child
The adult worms live in the host's cecum. From there they migrate to the perineum at night to lay up to 15 000 eggs at one time, which can be viable for up to 2-3 days. The eggs can be spread by their presence on the host's hands, in the bedsheets, or in dust, thus infecting the entire family. Ingested eggs are hatched in the duodenum and migrate to the large intestine, restarting the cycle.
