People often ask if can poison ivy spread to others by touching. Poison ivy rash is an allergic reaction, not a disease. So, you don’t risk infecting those around you. Knowing how it works helps ease your worries.
The Role of Urushiol Oil
The rash is caused by urushiol oil from the plant. This oil makes your immune system react. It’s key to know that how can poison ivy be spread is only through direct contact with this oil.

Why Blister Fluid Does Not Spread the Rash
