My daughter, we just found out, has fifth disease. She has been incubating it for some time, as she currently is beginning to show signs of the rash. I m sure I ve been exposed to it several years ago, and am confident that I m immune. If I am immune, can I pass it along to a one day old newborn? But if I am not, and I do pass it on to him, is he in greater danger of complications, being so young?
