However, poison ivy rash is possible if you touch plant resin that is still on the person or contaminated clothing. This is partly true, partly myth.
Poison ivy rash itself is not contagious, says UAMS Dermatology Clinic. Fluid from blisters from a poison ivy rash won't spread poison ivy either. 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.
Poison ivy rash, which is caused by an allergic reaction to oil on the plant, is not contagious. Even the liquid in poison ivy blisters is not contagious. Only direct contact with the plant's oil, called urushiol, can trigger poison ivy rash. 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.
Just as a person can get poison ivy rash if you touch skin contaminated with urushiol, you can transfer it to other parts of your own body while the oil is still on the skin. 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. Finding poison ivy is easy in the United States, where it grows virtually everywhere except Alaska, Hawaii, and some desert areas of the Southwest. Poison ivy is a vine or shrub that has three shiny leaves and grows in much of the United States and Asia.
Dermatologists suggest that the first exposure to poison ivy has an incubation period of about five to 21 days before the rash appears. 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. Poison ivy rash often appears in a straight line because of the way the plant rubs against the skin. Poison ivy rash isn't fun, but if you're smart about removing urushiol from your body, clothing, and anything else that might be contaminated with it, you can help prevent other people from getting it and prevent you from becoming infected again later on.
In addition, thoroughly washing clothes that may be exposed to the oily chemical is key to preventing the spread of poison ivy. 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. If you scratch a poison ivy rash, bacteria under your nails can cause the skin to become infected. People with poison ivy rash usually don't require medical attention, and symptoms resolve in about one to three weeks.
Poison ivy rashes may appear to spread if urushiol oil gets trapped under the nails and the itch is scratched. That's why it's important to clean all items and pets that come in contact with poison ivy. . .
