In brief: When active

Most of us harbor herpes virus in our tissues, having been infected years earlier (often asymptomatically).
For a variety of reasons we get intermittent symptomatic eruptions as "cold sores". There is some evidence to suggest, however, that viral shedding may occur without having overt symptoms.
