Cold sores are not restricted to these common places, but can also show up on any body part including genitals as well. These “below the belt” blisters are caused by another herpes simplex virus i.e. HSV-2 and mostly occur due to sexual contact.

Anyone who has had a cold sore outbreak will easily recognize a reoccurrence. A recurrence infection is always less severe and short-lasting compared to the primary one.

Around 90% of adults have HSV in their bloodstream, which means they have been infected with this virus some or the other time in their lifetime.
