It is usually not hard to identify a child with a poison ivy rash, especially a classic case of poison ivy.

Kids with a classic poison ivy rash might also have a history of a known exposure to poison ivy after a camping trip, hike in the woods, or day at the lake.

After exposure to the leaves, stems, or roots of a poison ivy plant, children develop symptoms of poison ivy within 8 hours to a week or so, including:

  • an intensely itchy rash
  • red bumps that often are in a straight line or streaks, from where the poison ivy plant had contact with your child's skin
  • vesicles and blisters that are filled with fluid
Keep in mind that children exposed to poison sumac and poison oak, other members of the genus Rhus or Toxicodendron, can get these same symptoms that are generically referred to as poison ivy symptoms above.

Other characteristic signs and symptoms of poison ivy are that the rash will worsen over days or weeks without treatment with steroids, the rash may not go away for up to three weeks without treatment, many children will have worsening symptoms with each exposure, and that some areas of a child's skin that had less exposure to the poison ivy plant will get the rash later than others.
