I talk about localized issue because I don't understand why if we had a weak immune system we wouldn't get sick all the time given that if a virus which is present in almost every person, only us are affected. I mean I have the Herpes virus -already took pills Valacyclovir with no effects- but I never have had a really cold sore, so I wonder why an other virus we almost all have just reveals like that, H24 7/7days without remission.
Either it's a very special virus, which I don't think because we come from all over the world, or it's simply a common virus which affected our lips externally when they were frail for whatever reason and actually just persists locally.
