What Causes Round Worms in Kids?

Roundworms live in the intestinal tract of the host animal and are transmitted through fecal material. Kids can be exposed to roundworms when they play in areas that have come in contact with contaminated fecal material. Infection occurs in children when these eggs or larvae are accidentally ingested. The roundworms infect the human's digestive tract and can migrate to other parts of the body causing more serious conditions, and in severe cases, can prove fatal. To avoid possible contamination it is important to be aware of the most common sources of infection among children.

Infected Animals

• According to the Centers for Disease Control, puppies as young as two to three weeks of age can already be host to a signifcant number of worms. Both cats and dogs have the potential to be infected and pass the eggs of roundworms through their feces. Roundworm eggs can also be brought into the home environment in fecal material on the bottom of the family pet.

Uncovered Sandboxes

• Anywhere that pets have been given the opportunity to defecate are prone to contamination by roundworms. Children love to dig and play in sandboxes, and cats love to use them as their outdoor litter box. If children come into contact with areas that have been contaminated with infected fecal material, they are at risk.

Lawn or Dirt

• Pets and other animals defecate anywhere they are allowed. Roundworm eggs and largae are very resilient to harsh conditions and can survive in their environment without a host for a very long time. The areas of possible contamination in a park where animals are allowed are countless.

Contaminated Water

• Roundworm larvae have been found in untreated water sources. If a child swims in an area that is exposed to animal feces, such as a river or lake, the chance of infection is a concern. Teach children never to drink untreated water or allow it to enter their mouth.
