Scratching poison ivy blisters will spread the rash.

Avoid excessive scratching of your blisters. Your fingernails may carry bacteria that could cause an infection.
Poison ivy rash is “catching.”
False. The rash is a reaction to urushiol. The rash cannot pass from person to person; only urushiol can be spread by contact.
