Poison ivy is a plant that is native to North America. This is a climbing vine that is related to the Cashew family. Poison ivy produces Urushiol or an oily chemical on the surface of its leaves.

Is Poison Ivy Contagious?
The poison ivy dermatitis is an allergic reaction that is caused when our skin comes in contact with the leaf surface of the poison ivy plant that has Urushiol. Inflammation is the body’s response to this chemical and hence is not considered to be contagious and cannot be passed on to others even by direct contact. However, it must be noted that if a healthy individual comes in contact with the urushiol or the oily chemical from the skin of an affected patient or the clothes of the affected individual, then the Urushiol can then stick to this person and cause a reaction seen with poison ivy.
So, it is highly important to clean off the skin and clothing that has been exposed to Urushiol and also not to scratch or touch the developing poison ivy rash, if it has not been cleaned off, as the person could transfer the oil to mouth, eyes, or other areas of the body. You can remove the Urushiol by showering with warm soapy water, and this could help in reducing the chance of any spread.
How Long Does Poison Ivy Last?
Now, let us come to the point, “How long does poison ivy last?” Well, in majority of the cases rashes and inflammation due to poison ivy lasts anywhere from 1-3 weeks and then they will gradually resolve. It must be mentioned that most of the rashes caused by poison ivy are mild. However, in extreme cases, the poison ivy rash can linger on for even a month or more after exposure and development of symptoms.
Although in most cases, there is no need for immediate medical attention for poison ivy dermatitis and home treatments are good enough such as calamine lotion, cold compresses, or a hydrocortisone cream, in situations where the individual experiences symptoms like eye welling, fever, breathing problems, dysphagia, and rashes that envelop the entire body then prompt medical attention is required so that treatment can be rendered for severe allergic reaction due to Poison Ivy.
