Pinworm likes to stick around

Pinworm eggs cling to surfaces and objects for weeks

Pinworm eggs can survive up to 3 weeks. The eggs may spread to shared surfaces such as toys, doorknobs, faucets, furniture, towels, and bedding.

PINWORM can infect an entire household
PINWORM eggs cling to surfaces and objects for weeks

Pinworm infections are highly contagious. That means the infection can spread easily. If one person in a house gets it, others will probably get it, too. These are called outbreaks. Pinworm infections tend to stick around in infected homes, daycare facilities, and schools.


PINWORM can infect an entire household

Pinworm can infect an entire household

Here’s how pinworm infection spreads from one family member to another:

When the female worm lays eggs just outside the anal area, this often causes intense itching. That's why the infected person will scratch his or her bottom. The eggs are sticky and hard to see. Pinworm eggs cling to the person’s fingertips without anyone knowing it. Everything the infected person touches, such as clothing, bedding, curtains, carpeting, towels, and toilet seats can get pinworm eggs on it.

Pinworm: more common than head lice The infection rate in a home with
pinworm can be as high as 50%.

  • An infected person touches something and leaves the sticky pinworm eggs there.
  • A family member without pinworms touches an object that now has eggs on it.
  • The pinworm eggs stick to the person’s fingers.
  • The person touches his or her mouth and swallows pinworm eggs without knowing it.
  • Once pinworm eggs are swallowed, the infection begins.


Why pinworm is so difficult to prevent

PINWORM eggs are so tiny, 1000 can fit on the head of a pin


  • A single female pinworm can lay up to 10,000 eggs on one person
  • Due to the high number of eggs, and because they are spread easily, house cleaning alone may not stop a pinworm outbreak
  • Pinworm eggs can be released into the air and can be inhaled by others when sheets or pajamas are shaken
