Poison-Ivy has small stems with 3 distinct leaves on each. I attached a picture link of the plant. Small bumps appear where it was touched if you're allergic to it. Bumps appear usually in a day or two after contact, and can secrete fluid that may help spread the rash because of scratching the area and spreading the fluid. Avoid touching eyes or mucous membranes before washing the exposed area, because Poison Ivy can spread to them. Be aware also of Poison-Oak and Poison Sumac, allergies to one usually mean allergies to all three.

Reply:Poison Ivy rash starts out as little itchy benign bumps about a day or 2 after exposure and then the skin turns bright red and blisters appear that ooze yellow junk. There is no way to know for sure at this stage, but it wouldn't hurt to put some anti-itch cream on the bumps anyway.
