Re Cold sore infection - My grandson was infected by the herpes Simplex Virus (cold sore virus) just after birth and spent his first six months of life in hospital, three of these on life support, and was on the liver transplant list until he was three. Now, aged five, he is having six month checkups, blood tests and endoscopes because his liver, is still scared and he has portal hypertension. Please please tell anyone with a new baby or anyone with a cold sore of the dangers of contact. It is only thanks to staff at the Bridgend Hospital who were vigilant and the care he and the family received at Birmingham Children's Hospital that we have him with us today.
