Shingles is not a contraindication to breastfeeding or using the milk. Like
any herpes lesion (varicella zoster is a herpes virus) you want to minimize
any infant exposure:
cover the lesion and wash your hands. I know of no research that suggests the
virus gets into breastmilk. Shingles is a local reactivation of virus living
in nerve endings, not a systemic illness.
