Poison ivy rash is caused by contact with urushiol, the oil in the leaves of the poison ivy plant. Only urushiol can cause a poison ivy rash. The pus that comes out of the blisters does not contain urushiol and does not spread the rash. However, poison ivy rash is possible if you touch plant resin that is still on the person or contaminated clothing.
Consequently, the diagnosis is made by the probable exposure to poison ivy and the appearance of the rash, the symptoms and signs described above. However, if a person comes into contact with the oily chemical on the skin or clothing of an affected patient, then urushiol could be transmitted and a poison ivy rash could develop in a second person. In addition, if the person who has poison ivy touches clothing or other areas of their body that have the irritant on the surface of the skin, they can spread the irritant to other parts of their own body. In addition, if for some reason a person burns poison ivy leaves, the oil can travel through the air and cause a rash in the nasal passages or other respiratory tract.
Poison ivy rash often appears in a straight line because of the way the plant rubs against the skin. Poison ivy rashes may appear to spread if urushiol oil gets trapped under the nails and the itch is scratched. If you scratch a poison ivy rash, bacteria under your nails can cause the skin to become infected. Most people with poison ivy will have the rash, and other symptoms and signs will gradually resolve over a period of about one to three weeks.
In addition to garden tools, your recreational team may find poison ivy and cause a rash. Poison ivy is a vine or shrub that has three shiny leaves and grows in much of the United States and Asia. For these reasons, be sure to clean your skin, clothing, pets, and any outdoor equipment to avoid re-exposure to poison ivy and developing an annoying rash again. In addition, thoroughly washing clothes that may be exposed to the oily chemical is key to preventing the spread of poison ivy.
Dermatologists suggest that the first exposure to poison ivy has an incubation period of about five to 21 days before the rash appears. However, repeated exposure to poison ivy causes the rash to appear more quickly (about 12 to 48 hours). People with poison ivy rash usually don't require medical attention, and symptoms resolve in about one to three weeks. .
