Pinworm infestations are more a nuisance than a major health problem. Vaginal discharge, itching and discomfort, if pinworms migrate into the vaginal opening.
Pinworms travel from the cecum to the rectum to lay eggs around the anus and buttocks.
The tiny eggs are picked up on the fingers by scratching. They also drift in the air, where they are inhaled or swallowed. Eggs hatch in the small intestine. The larvae travel to the cecum, where they mature, mate and repeat the cycle. Poor personal hygiene.
