Pinworms—also known as seatworms and threadworms—are little parasites. When someone has pinworms, it is also known as a pinworm infection.3

PINWORM infection is 3x more common than head lice

Once a person touches pinworm eggs, usually from scratching their bottom, the eggs can be spread to other objects and surfaces, putting others at risk for infection.1
