- About 50% of children exposed to poison ivy or poison oak will develop an allergic reaction.
- The best strategy is prevention by avoiding contact ("Leaves of three, let them be").
- If exposed, wash the affected area promptly with soap and water to reduce rash severity.
- Itching relief can be managed with ice cubes, hydrocortisone cream, and antihistamines.
- Severe reactions may require oral steroids prescribed by a healthcare provider.
- The rash typically appears 1 to 4 days after exposure and is not contagious. Children can still attend childcare despite the rash.
- The rash may appear to spread but this is due to different areas reacting at different times.
