Great link the second one. Really worth reading. It adds support to my knowledge...
My wife keeps telling me that always when I get herpes on my lips or nose, she starts to feel worse (her leg gets weaker, her fingers are more numb...). Or when she meets her mother or anybody with herpes. Either few days before outbreak or the same day. I still cannot 100% believe it. She even doesn't have antibodies to HSV-1/2 in her blood. That's another surprise how come she didn't get it from me yet.
Herpes is not be airborne transmitted. But the viral replication and shedding can occur at any time of the year.
The only explanation I can understand now is that there must be some upper respiratory tract infection (rhinovirus, adenovirus...) that I or other people get, that awakes their herpes outbreak or shedding. From my experience, respiratory infection is like 50% higher chance for an outbreak. All the other known factors (sugar, alcohol, arginine rich foods, stress...) can then only make the outbreak bigger or smaller. The same infection that awakes herpes in me can awake some other herpes in my wife (e.g. EBV, CMV...) or even directly this new one HERV-W retrovirus. It's hard to understand but in any case doing as much as possible to avoid infections is probably the key for us.
