Threadworms in human are intestinal parasites that commonly infect children. Threadworm is known by its Latin name Enterobius vermicularis and belongs to the class of parasites called the helminthes. It is sometimes referred to as pinworm or seatworm. The threadworms do not transmit to and from animals. However, their eggs can stick to the animal fur.

Threadworms infest humans due to poor hygiene habits. The eggs of the threadworm get transferred from the anus to the mouth or other surfaces. These eggs then get transferred into a healthy individual coming in contact with the infected surface. These eggs can stick to the underwear or clothes, bed sheets, towels and even carpets.

If the person scratches the anus, the eggs get transferred to the fingertips or nails. When the person touches other surfaces like kitchen utensils, furniture, toothbrush, toys, bathroom or kitchen countertops, the eggs get transferred. These eggs survive on the surfaces for 3 weeks and get transferred to an unsuspecting individual. A person can also breathe in the eggs or swallow them. Once swallowed, they can hatch in the intestines leading to intestinal infection.

The female and male threadworms mate after which the male dies. The female migrates to the anus and lays thousands of tiny eggs around the anus and in females the eggs are laid around the vagina. The female threadworm lays her eggs at night mostly when the infected person is sleeping. The female threadworm secretes mucus while laying eggs that causes the area to become itchy. When the person scratches the area the eggs can stick on the fingertips and fingernails. These eggs then get transferred to the mouth, clothes and other surfaces. If these surfaces or clothes are touched by other people, the eggs may get transferred to the mouth. The eggs can survive three weeks before hatching. The hatchlings around the anus can re-enter the bowel area. If the eggs have been swallowed, they hatch inside the intestine. The hatchlings feed from the nutrients present in the large intestine. After 2 weeks, the worms become the size of an adult and reproduce again.

These threadworms are visible to the naked eye that look similar to cotton threads. An adult female can reach about 8 to 12 mm long and the male is about 2 to 5 mm long.
