How many pinworms do you get in one night?

Pinworm is a common intestinal parasite that occurs in economically backward and resource-poor areas. Every night, female pinworms crawl to the anus to lay eggs, which can cause severe itching in local areas. The number of pinworms crawling out depends on the severity of the infection. Mild pinworms may only expel a few or a dozen, and severe pinworms may crawl out twenty or thirty.
