Number sign. Not to be confused with the Chinese character äº, the sharp sign (â¯), the viewdata square (â), the numero sign (â), the equal and parallel to symbol (â) or the game Tic-tac-toe's grid. The symbol # is most commonly known as the number sign, hash, or pound sign.
The poison ivy rash is not contagious. When a person touches the poison ivy leaf, a substance on the surface of the leaf (a resin) rubs off. Over the next 48 to 72 hours the skin reacts to the resin by becoming red and developing bumps and blisters at and around the site where the resin was.
I was wondering if poison ivy/oak is contagious. I work at a day care center and my director says if the child brings in the leaf or bark from home then it can be cantagious. A parent says that if the child scratches the infected area, opens up a blister, and then touches another child, it will spread on that child.
