Poison ivy and other poisonous plant eruptions cannot be transmitted from person to person. However, it is possible to get a rash from vegetable oil that may have stuck to clothing, pets, gardening tools, and other items that have been in contact with these plants. Vegetable oil stays (sometimes for years) on virtually any surface until it is washed with water or isopropyl alcohol. The rash occurs only where the vegetable oil has been in contact with the skin, so a person with poison ivy cannot spread it through the body by scratching.

The rash may appear to be spreading if it appears over time rather than doing it all at once. But this is because vegetable oil is absorbed at different rates in different parts of the body or repeated exposure to contaminated objects or vegetable oil trapped under the nails. Even if the blisters rupture, the liquid in the blisters is not vegetable oil and can't spread the rash any more. Bacteria from under the nails can penetrate them and cause an infection.

Rashes, blisters, and itching usually go away in several weeks without any treatment.

More than 4 in 5 people will develop an itchy, red, inflamed skin rash when they come in contact with poison ivy and its urushiol oil. Toxicodendron plants, such as poison oak, ivy, and sumac, are poisonous plants that can secrete a toxic oil called urushiol.
