The potential problem HSV-1 is a virus that usually causes cold sores or fever blisters around the mouth, but can also cause similar blisters anywhere on the body above the waist. HSV-2, also a virus, usually causes genital sores or blisters. In the United States, nearly 80 million people have some form of herpes.

However, your baby could get infected by touching a blister or sore on your breast, mouth, or other area of your body. To avoid spreading the virus, always keep clean clothing between your baby and any affected area of skin. Thoroughly wash your hands after using the toilet or touching a sore, and wash your hands and lay a clean towel or receiving blanket on your lap before holding your baby.
