It doesn't matter...: ...how long the virus can survive. In HSV infection present for more than a few months, autoinoculation (self transmission to a new part of the body) almost never occurs, except rarely to an eye. The immune system prevents it. Use common sense hygiene (hand washing, alchohol gel) but no need to be compulsive about it or worry about transmitting oral herpes to, say, the genital area.
