Risk factors for ascariasis include:

  • Age. Most people who have ascariasis are 10 years old or younger. Children in this age group may be at higher risk because they're more likely to play in dirt.
  • Warm climate. In the United States, ascariasis is more common in the Southeast, but it's more prevalent in developing countries with warm temperatures year-round.
  • Poor sanitation. Ascariasis is widespread in developing countries where human feces are allowed to mix with local soil.
