A book with an infectious disease? Someone opened it an it came out, or something like that. [s]

I've never read it before, but I'm pretty sure it has the word "Orange" in it. The cover was quite orange. It was about these kids that went to a library or something and picked a book from the shelf. They then opened it and some old disease came out. Not sure what happened in the end.
