Jeez is this STILL going on
COLD SORES ARE NOT STIs - the Clue is in the S it stands for SEXUALLLY
some if the ignorance on this thread is seriously disturbing
& is not helping the OP gain a reasoned attitude
Mmmmm - I wonder how the thread might take a turn if it turns out the OP is actually a disgruntled Dad trying to find dirt to throw at his ex ?? - just a thought for those of you with some serious issues around germs
- not that is SHOULD make a difference of course, but I wonder 
slightly off topic, but relevant due to some of the hysterical & inaccurate replies on here
- We live in a world FULL of Viruses & Bacteria, you CANNOT avoid them, even for a new born, & you would be doing your baby no favours if you did, because THAT is how we all gain our immunity
If you think Cold Sores are so scary, look at some of the others - streptococcus for example is on & in EVERYONE of us & everywhere we touch or go - you CANNOT avoid it - & chances are it will not do you any harm, bar maybe a sore throat, its a very harmless bacteria - unless you 1 of a tiny percentage who are unlucky enough for it to become something serious, such as Septiceamia - then if you are lucky after a serious illness & hospitalisation you might eventually recover, but will never be quite the same again - if not you might lose a limb - or DIE!!
So what are you going to do, live your life in a Bubble?? - of course not
