Some people are extra-sensitive to the oil that causes poison ivy rash, and this tendency appears to run in families.

Outdoor occupations and hobbies can put you at higher risk for exposure to poison ivy, poison oak or poison sumac. Examples include:

  • Farmers
  • Foresters
  • Landscapers
  • Gardeners
  • Firefighters
  • Construction workers
  • Cable or telephone line installers
