A pinworm, scientifically known as *Enterobius vermicularis*, is a tiny parasitic nematode that infects the intestines of humans, especially children. These worms reside in the large intestine and rectum. Female pinworms migrate to the anus to lay eggs, causing intense itching. Transmission happens through fecal-oral contact, often via contaminated surfaces or fingers. Pinworms are like the annoying little siblings of the worm world, always causing mischief. 😈
