What is Poison Ivy Rash?

Poison ivy rash is a­ common type of skin rash caused by poison ivy, a plant native to North America and Asia. You will likely have an allergic reaction when you touch poison ivy leaves or come into contact with its oils some other way.

Poison ivy rash can­ easily be recognized by characteristic symptoms such as redness, swelling, and itchiness in the affected area. The rash should go away on­ its own within two weeks. During this time, you can­ apply some home remedies to­ ease the symptoms or, in more severe cases, use­ medications recommended by­ your­ healthcare provider.

How Common is Poison Ivy Rash?

Poison ivy rash is a very common type of skin­ rash. According to the Centers for Disease Control and Prevention (CDC), 80 to 90 percent of people develop it after coming into contact with the plant’s oilsTrusted Source – urushiol. Fifty micrograms (μg) of urushiol, which is less than one grain of table salt, triggers a reaction in most people.

Anyone can be affected by poison ivy rash, regardless of their age and immune system performance. Even if you had a rash in the past, you may develop it again.

How Dangerous is Poison Ivy Rash?

Poison ivy rash is not considered dangerous. It is not commonly associated with life-threatening conditions and is unlikely to cause more problems besides the rash. Exceptions to this rule are breathing difficulties, which may occur due to inhaling the oil produced by poison ivy. However, this is also an­ uncommon scenario requiring a plant to burn to release its harmful compounds into the­ air.

Is Poison Ivy Rash Contagious?

Getting a poison ivy rash from another person is very unlikely. The oil released by poison ivy – urushiolTrusted Source – is quickly absorbed by the skin. Because of that, it is also rare to transmit the oil to other parts of your body by touching the affected area.

Risk Factors

Many people in­ America, sometime in their lives, get a rash from poison ivy. It’s surprising how easily someone can catch this skin problem. If you touch the plant that grows almost everywhere—like parks where people walk for fun, green woods made for looking around, or rough paths where they go hiking on weekends—you might get its oil on your skin and have trouble with irritation.

Surely, doing things outside makes it more possible to get a rash from poison ivy. These activities especially increase that chance:
