In reading about thrush, I came across a bit about chicken pox that is interesting. This is from a unit on Candidiasis and Breastfeeding by Amir, Hoover, and Mulford.IT is a xerox copy that I have. "Herpes zoster(shingles) may cause pain in one breast preceded several days by a rash which commonly looks like papules (red bumps), sometimes vesicles(small blisters), and occasionally bullae(large blisters). DIRECT CONTACT MAY CAUSE CHICKEN POX IN THE BREASTFEEDING CHILD. (emphasis mine) Ellen in Pittsburgh Sounds like if a mom has chicken pox her babe could get it from contact with the blisters.
