The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress. They are therefore resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation, and chemical disinfectants.

Cold sores and fever blisters tend to develop when an individual has a cold or fever but can also be triggered by sun exposure, emotional distress, intestinal illness and menstruation. These blisters can recur in the same spot or in different locations with a frequency ranging from weekly to yearly--some people infected with the virus never develop blisters.
