1 doctor agrees

In brief: Yes

Poison ivy (in eastern us), oak (in western us), sumac (in eastern us) are 3 species in the genus toxicodendron or rhus which all produce urushiol oil, the substance that in sensitive individuals produces contact dermatitis.
Urushiol is very stable and can be blown on leaf particles into contact with the skin or carried on clothing for over a year so dermatitis can occur without plant contact.

In brief: Different plants

Same clinical presentation of contact dermatitis.
Treatment is the same. However, these are two different plants.
