Susan Grant, a gynecologist in New York, said rupture or mouthflow was a strain of the disease, which meant it was highly contagious and could happen over and over again. They can appear at any time, especially when your body is in stress or undergo hormonal changes that make pregnancy a key time for an outbreak.
You may feel (but do not see it) a mild fever or sore throat on your lips that indicates an outbreak of the disease may occur. But because it's a local infection, so there's nothing to worry about and no way for herpes to pass through the protective bar to your growing baby.
However, if it occurs after giving birth, do not kiss your baby, and do not touch the wound without first washing your hands with soap.
You are most at risk when the egg breaks out or becomes red. You can reduce the incidence of outbreaks with non-prescription painkillers and anti-viral drugs.
